I painted MM-151ST with
FOSTEX FE103-Sol
which I bought two years ago, so I will
send you the photo. |
|
A black
painting was
applied as
the base coat on the surfacer.
And I
overpainted
japan-looking waterborne
urethane paint:
Kamakura-Red
to the image of FE103-Sol.
FE103-Sol
Seen
through a black base
from under brush marks,
the
painted surface looks like
a wood grain.
I feel like
MM-151ST with
FOSTEX FE103-Sol
became the finely
sound
after the painting.
It had a taste both sound
and
appearance that commercial |
MM-151ST with FOSTEX FE103-Sol
|
|
loudspeakers don't
have.
MM-151ST with FOSTEX FE103-Sol is
connected
with a digital amplifier S.M.S.L SA-36A
pro,
and I listen to the network source by
a
single-board computer RASPBERRY PI with a music player
VOLUMIO
every day.
It provides excellent sound in
performance of a cost.
The digital amplifier enhances a
fine refreshing sound of the middle
and the high
frequency ranges, therefore, it has the
maximum
refreshing sound.
So I listen to newly bought
CD by this system first to make sure
the recording
state.
MM-151ST with FE103-Sol also has a natural
refreshing sound
in the low frequency range.
The
voluminousness of low pitch sound is not lacking, but I feel
a lack
in it a little due to the character of the digital
amplifier.
I want to boost the low pitch sound if it has
a tone control because
it plays low pitch sound of good
quality.

I was listening to jazz
and rock by my own back loaded horn
speaker
when I was young, but I listen to classical music
a lot
by foreign loudspeakers with age.
This is
because my opportunities to attend a classical
concert
have increased.
Recently the
digital-remastered old-time jazz and rock records
started
being sold, so I came to listen to old-time records
too.
"I want to listen to the back loaded sound
again"
I placed MM-191T with Audio Nirvana
Classic 8" Cast Frame together
with ANTHONY GALLO
Reference 3.5 and TANNOY Turnberry/SE.
I listen to
old recording sources through TANNOY Turnberry/SE,
and it
plays music which is not obtained by another
loudspeaker.
Turnberry/SE produces deep bass sounds, and
it makes
the whole room like a musical
instrument.
FE83En
9-channel surround system
added with 4-channel of FOSTEX FE83En
to ANTHONY GALLO
5-channel surround system is for AV
and
new recording sources.
My 9-channel surround
system reproduces the sound of a concert hall
with
reality.
It has a subwoofer amplifier, so my 9-channel
surround system
plays a voluminous bass like a super
woofer. |
|
MM-191T with Audio Nirvana Classic
8" Cast Frame
|
|
The scale of MM-191T with Audio
Nirvana Classic 8" Cast Frame is
comparable to TANNOY
Turnberry/SE and 9-channel surround system.
A blast
of this horn can not be listened
unless it is a large
sized back loaded horn system.
I think that the sound
pressure level is more than 95dB.
Jazz piano that is
played by MM-191T with Classic 8" is realistic tone
and a
beautiful.
I had the impression that the performer plays
the guitar, saxophone
and the trumpet under my
eyes.
The electric bass is powerful, and the lowest note
extends well.
I can hear the sound of snare drums and
cymbals clearly, it's exactly
a live
atmosphere.
A high note is noisy when I listen
to rock.
So I turned down the treble and boosted the
bass.
The sound of MM-191T with Classic 8" suddenly
became
extremely powerful sound as a
result.
The texture of a drum is really
amazing!
Audio Nirvana Classic 8" Cast Frame matchs
guitar playing very well,
and its vocal is also
beautiful.
Maybe no one can tell the pressure and the
power of surging sound
from MM-191T with Classic 8" until
hear it.
It would be difficult to get such a loudspeaker
on the market.
The biggest point of Hasehiro back loaded
horn is a bass
tone.
It is not deep bass, it has a good rising
and falling characteristics.
In some cases, bass comes
too strongly out of
back loaded horn speaker
system.
But MM-191T moderates the voluminous, and
extends
the reproducing limit with a good damping
performance.
Audio Nirvana Classic 8" Cast Frame also has
a good rising and
falling
characteristics.
So they match each other very
well.
|
|
Combining amp was tube
integrated
amplifier McIntosh MA2275.
So, the thick middle-low tone
suited
MM-191T.
Now it has switched over
to
separate amplifiers
LUXMAN
C-600f with
M-600A.
As a result, the transparency of
the sound
increased, and it became
a clear sound with good
balance |
| upside |
LUXMAN C-600f |
| downside |
LUXMAN
M-600A |
|
|
over the whole sound
region.
I think that new recording sources match with
LUXMAN C-600f
with M-600A having
both of power and delicacy.
I feel that LUXMAN
C-600f with M-600A outrank McIntosh
MA2275
as the whole.
But I choose McIntosh MA2275 for
hot performance of jazz and
rock.
|
|
|
In passing, I switched to
a
digital amplifier made in China;
S.M.S.L SA-36A
pro.
Because I felt that MM-191T with
Classic 8" is
well suited for
a digital amplifier.
SA-36A pro
on McIntosh MA2275
looks like a toy.
Both price and
weight are almost
only 1/200 compared with MA2275.
"I
thought so." |
| upside |
S.M.S.L SA-36A pro |
| downside |

|
|
MM-191T with Classic 8" played
music by
better-than-expected sound
that has hardened quality
by LUXMAN C-600f with M-600A.
I already knew that
the sound is thinner and the sound field is
narrower
compared to those by C-600f with M-600A.
But the
performance of MM-191T with Classic 8" by SA-36A pro
has
the most speed over the whole sound region
among the 3
amplifiers.
It is a satisfactory megavolume at
around 10:00 of
the volume control knob because
MM-191T with Classic 8"
has a high SPL, but a bit
short of the voluminousness of a bass tone
because
SA-36A pro doesn't have a tone control.
So,
forcefulness is not enough.
But I think it can't be
helped due to a cheap switching power supply.
Perhaps
SA-36A pro will make play the same kind of bass
as
another 2 amps if it is a high-quality power
supply.
Classic
8"
MM-191T with Classic 8" plays a
strong sound, so I can say
the sound is right because a
digital amplifier makes less dense.
I think anyone can
enjoy a wonderful music without waste money
if it is a
combination of Hasehiro back loaded horn
system and
a digital
amplifier.
Beyond that, the person can buy a lot of
favorite CDs, and will also
go to costly concerts by
using the surplus.
I thought that it would be happy
to music lovers.
The defects of MM-191T with
Audio Nirvana Classic 8" Cast Frame is
that it is not
completely suited to the person who pursues healing
to
music, because its sound does not have
softness and a puff feeling.
The high-pitched tone level
is high but not flat, and yet
it does not have
exaggerated feeling.
MM-191T with Classic 8" plays any
instruments by a realistic live tone.
But anyone will
probably feel annoyed with it if does not pay
attention
to the music due to special features of Classic
8".
As tone control, I think that increasing the
weight of MM-191T
is effective.
I think it is better
if lead sands are spread all over
the back of
the horn opening, but I might become unable to
move
MM-191T if so.
Further, I want to increase the
reverberation sound of MM-191T
a little more because I
usually listen to music
having much indirect
sound.
Additionally, the sound of MM-191T may change by
replacing
the side boards and the front baffle
boards
with the resounding boards. And coating
of MM-191T.
Thank you for your wonderful Hasehiro
speakers.

I listen to music without
delay.
I'd been using 20cm bass reflex with a
subwoofer up until now.
But I wanted to be able to hear
back loaded horn sound, and so
I bought SSC coated
MM-181T and FAL C60 N 50neodymium.
Actually I
wanted much larger FAL C90, but it didn't fit my
budget.
C60 N
The
low-pitched sound is on a solid basis,
and that sound is
full of realism.
I feel as if sound images are localized
than before.
I like movie music, and that, perhaps, I
feel my favorite genre is fit
for back loaded
horn system.
I want to compare after changing the
crossover network
and the sound pressure level,
etc.
SSC coated MM-181T with FAL C60 N 50neodymium is
good
if listening to classical music and movie
music.
But I think the smaller MM-T is good if
listening to lively pop music
and in case of current FAL
C60.
Because I think it plays too much low-pitched
sound. |

September 2015 |
MM-151 arrived the other
day.
I assembled it and mounted FOSTEX FE103-Sol (16Ω) on
MM-151
immediately.
Unlike another back loaded horns,
Hasehiro back loaded horn has
something different, and
it's well-made.
It has amazing sound, and its tone
quality is soft.
MM-151 with FOSTEX FE103-Sol (16Ω) is
just like
a small TANNOY Stirling.
I think this MM-151
matches 300B tube power amp. |
|
MM-151 with FOSTEX

There is a knack in playing the
back loaded horn system.
Especially, there is a
difference in the middle-low tone
between transistor amp
and tube amp.
Back loaded horn system matches tube
amp,
it has a very different harmonic overtone.
Among
that, 300B tube is further matched with
the back loaded
horn system between 2A3 and 300B.
MM-151 with FOSTEX
FE103-Sol (16Ω) plays music by a sound equal
to
TANNOY Stirling in spite of just 10cm.
FOSTEX
FE103-Sol (8Ω) is virtually unobtainable now.
So I bought
FE103-Sol (16Ω) under unavoidable circumstances,
but it
seems like it has good chemistry with MM-151.
FE103-Sol
Hasehiro back loaded
enclosures have an
exponential curve,
so they
have very few standing
wave.
As the
result, they have very pure sound.
I have heard the sound
of SWAN designed by Mr.Tetsuo Nagaoka
a long time ago.
But I think
MM-151 with FOSTEX FE103-Sol (16Ω) is better.
I
appreciate your continuous support.

FF105WK
MM-151S with FOSTEX FF105WK was
assembled yesterday,
and it played music.
It had a
good match with MONITOR AUDIO GS10
in spite of a single
10cm full-range drivers.
It was beyond my
imagination.
I want to go out with MM-151S with FOSTEX
FF105WK
for a long time.
I overdid it and
put
Dvořák: Symphony No.9 "FROM THE NEW
WORLD".
MM-151S with FOSTEX FF105WK successfully
completed
the first movement "Adagio", but screamed
in
the last movement "Allegro con fuoco".
I will use it with
care.
I fixed the front baffles with wood
screws.
I
am glad that I could find MM DIY box, and I will
order
the wooden speaker grills later.
Thank you very
much.

I didn't know PARC Audio until

And I mounted PARC Audio
DCU-F131W on upgraded MM-161S
from MM-151S.
The
straightforward low tone spreading downward was
true
to everybody's reputation.
MM-161S with
DCU-F131W played bass drums and base beat
of PLAY BACH by
Jacques Loussier Trio powerfully
with
beautifully.
Furthermore, the high tone jumps up
sharply,
and the attack of a piano is beautiful,
too.
I am happy to be able to listen to particle of
sound
of the string quartet.
I had a blissful time
when I listened to Franz Joseph Haydn.

MM-171T with FOSTEX FF165WK is assembled
at today's evening.
It is very good sound, and I amn't
tired from listening the sound
even in long
listening.
I listened to Charles Camille
Saint-Saëns,
Symphony No.3 "ORGAN" on SACD as
the first music.
Because that is the SACD that lead
me to wanting more bass tone.
I had heard the lowest bass
tone of pipe organ with a clouded sound
up until today,
but MM-171T with FOSTEX FF165WK plays it
with a
solid sound.
And also, it plays individual instruments
loudly and clearly
having a modulation feeling.
I
should be able to enjoy, thank you very
much.

Thank you
for your shipment.
I assembled MM-141S with PeerLess
TG9FD-10-04 immediately,
and I continued to spin music
for half a day.
I was amazed to listen to piano
solo.
It sounds like a live piano performance in front of
me.
This is just 3D sound.
Violoncello is also so
good, I can hear the unimaginable vibrancy
of the
strings.
For the time being I enjoy listening to my CDs
again.
Thank you for the great
encounter.
PS
Recently I'm listening to
music with shifting amps:
tube, transistor and
Chinese-made digital amplifier.
I completely
understand each difference.
I should have bought MM-141S
much earlier.
Although back loaded horn system, it's
small full-range speaker.
I didn't expect much without
hesitation,
but MM-141S with PeerLess TG9FD-10-04
performed
at a level beyond my imagining.
Next time I
want to try a different speaker driver.

― Custom-Ordered
MM-191T ―
Report from
Hasehiro
The order is SSC coated
MM-191T and matte-black
urethane painted assembly.
I
recommended L.Cao FA8 Alnico from his favorite musical
genre,
and he decided in this combination.
I spent
about three months to complete. |
|
urethane painted SSC-MM-191T with L.Cao
FA8 Alnico
|
I started listening to string music
because L.Cao FA8
has alnico magnet.
Then I heard
long-forgotten wonderful tone downright.
It had a
huge similarity
to my favorite nowdefunct great
masterpiece Roiene RA160.
I made and sold double-layered
hybrid back loaded horn enclosures
with Roiene
RA160.
At first, I mounted it on WCW-160 for 16cm drivers, and then,
mounted it
on WCW-200 for 20cm drivers as WCW-2016R.
Everybody
loved the tone of WCW-2016R
and it took constant many
orders.
WCW-2016R created distinctive atmosphere,
especially strings.
Sometimes,
WCW-2016R played violoncello
in a deeply melancholy
tone.
I felt twinges of horror by the tone,
and
fought off a sob.
Sweet high note of top E string
of a violin was
very beautiful, and brought me to
dream world.
WCW-2016R made music light and
dark,
and added depth to performance.
WCW-2016R
arranged music with the spirit.
WCW-2016R was
discontinued unwillingly
despite healthy sales
because Roiene Audio
closed a business without
previous notice.
Since then I met various wonderful
drivers
both foreign and domestic,
but |
WCW-2016R
| haven't met driver very similar to
Roiene RA160's tone.
This MM-191T with L.Cao FA8
Alnico is quite similar to the tone
of that
WCW-2016R.
All in all the strings are
wonderful.
Violoncello is a melancholy soft tone, and
there is intonation
in the
performance.
It creates a distinct
atmosphere.
Vocal is also very wonderful. I guess it's
because it has
a high sensitivity.
I'm tempted by the
words if it's an expressive singer. I guess it's
because
I can hear vowel clearly.
This combination of MM-191T and
L.Cao FA8 Alnico is acclaimed by
Hasehiro listening
room's outspoken regulars, too.

Mr.M, Hiroshima
City
January
2015 |
Nearly 6 months have passed since the
arrival of
urethane painted SSC-MM-191T with L.Cao FA8
Alnico.
I listened to different genres of music in this
aging period;
classic, wind-instrument, jazz, rock, pop,
Japanese traditional,
folk music and the rest.
Just
mention about classic music is symphony, orchestral
works,
chamber music, instrumental, chorus, lyrics and
the rest.
 |
In a word,
This speaker system plays
the
beautiful sound doubly
beautiful,
and it plays other sound
in its own
way.
I'm sure that this speaker system
gives an
answer directly
about good and bad recording
of
the sound source.
I dare say as a general
reminder.
This speaker system playing
strikes a
sympathetic chord
like an instrument
if its
recording is good.
Depending on the sound
source,
this speaker system
playing | has the beauty of a splendid and a sensitive
landscape,
also it provides coquetry like naked
body.
I knew back loaded horn speakers designed by
Mr.Tetsuo
Nagaoka,
but I
listened to sound itself for the first time by this
purchase.
This was a great adventure for me, but
I feel fortunate
that my first listening back loaded
sound is
Hasehiro exponential
curved horn speaker system.
Perhaps I didn't
purchase back loaded horn speakers
if my first listening
back loaded sound is Nagaoka design models.
I have been
audio nut for 25 years, but SSC-MM-191T with FA8
Alnico
brings endless surprises and discoveries.
It
was so good I added the finishing touch on my audio
system
with this speaker system.
It's most thoughtful
of you to accept my selfish.

It was not that easy, but my MM-191T with FOSTEX
FE206En
became the only loudspeakers in the
world.
Additionally I hung 10 Lipton® tea bags
in
the air chamber of MM-191T
as sound absorption
material.
The bass volume increased more than
doing
nothing at all.
Some back loaded horn
owners overlay
black cobbled
stones to
cover the bottom
of the horn opening.
So I
overlaid it to cover the bottom of
the horn opening
for my MM-191T. |

FOSTEX FF225WK arrived, and I

I had
used JBL

date.
FF225WK
Compared to
JBL 4312D, MM-191T with FF225WK is;
1.
It
has a strong vocal.
2.
The middle-low range
was spread.
As a result, I found the sound, which could
not to be heard until now.
3.
Energetic
feeling was obtained on the whole music.
4.
The whole
sounds are getting a good balance.
5.
It
vividly conveys the tone of a musical instrument and so
on.
I might give many improvements.
Such is
Hasehiro back loaded horn
system.
In my
submission...
MM-191T with FOSTEX FF225WK passed JBL
4312D.
MM kit brings the pleasure of making and such
a wonderful sound.
And I get attached to it watching the
MM-191T.
I'm glad that I met Hasehiro Audio
and
finally obtained the back loaded horn speaker I had
wanted
for a long
time.

― Custom
MM-181 with Four Eyes ―
Report from
Hasehiro
I received a unique
custom loudspeaker with the client's idea.
It's
MM-181K carrying 4 drivers.
I have ever produced
custom loudspeaker with 2 drivers
but never produced
it with 4 drivers before.
Calculated
simply, the area of those 4 diaphragms largely similar
to
one 16cm driver, but is there a clear jump in
sound?
MM-181K-mounted drivers are FOSTEX
FE83En (8cm).
FE83En
I wired four
FE83En drivers in parallel after completion
of the enclosure, but it was a hard work
due
to the small baffle aperture.
Strange face
with 4 eyes looks deadpan,
but the sound of the
MM-181K with four FE83En drivers
was
better than expected. |
bonded type painted
MM-181K with 4-FOSTEX FE83En
|
Sound source is diffusely spread
from 4 points,
so it feels like it sounds from a
larger area than one 16cm driver,
and it has
non-irritating mighty sound.
It's certain that this
MM-181K has a much clearer and finer sound,
and
also greater sense of speed than one 16cm driver
by
a difference in moment of inertia.
This advantage is easy to
understand when listening
to a big orchestra.
A wide
full-range driver is unreasonable to play many
instruments
at the same time, it often makes the sounds
into a ball.
But the method of this MM-181K can
completely separate
multiple instruments, and it can play
a symphony with comfort.
Even so, the low tone
fell short of expectations.
I think it will result in a
different outcome from that if these 4 drivers
are
DIY Audio SA/F80AMG instead of FOSTEX
FE83En.
― Comment from The
Client ―
Sure the bass is poor, but
it's hard to imagine that powerless FE83En.
It plays
light and unfaltering sound.
Even when I turned up
the volume, it playd the sound
solidly.

I bought MM-161T
and PARC Audio coaxial DCU-C171PP
that Hasehiro
introduced to me.
That was six months ago, I am very
satisfied.
I need a loud boom of gran casa, so I have
added a super woofer.
DCU-C171PP
coaxial
I
challenged the painting of MM-161T during the consecutive
holidays
because I have been thinking about it since
before.
It is not only the outside but also the inside of
MM-161T
including the air chamber, the throat and the
horn.
I wanted to improve the sound quality of
MM-161T with DCU-C171PP
by hardening the inside.
1.
I broke down into components,
and sanded all boards
with abrasive
paper.
2.
I applied abrasive
grain on
all of the boards, and sanded them
with abrasive
paper.
3.
I applied
oil-based
varnish to
all boards, and sanded them
with abrasive paper.
(repeated 3 times)
I spent 10 days to reassemble
MM-161T with DCU-C171PP.
The side boards having a
wide area became the painting unevenness,
but it is
bathed in an amber light and has turned out well as a
whole.
Due to loose sound, black cobbled
stones
were spread all over
the air chamber and the horn-opening
area.
And I put coconut husk
charcoal
pack as absorption material,
one pack in the horn and two
packs in the air chamber.
Furthermore, I hung 4
Lipton® tea bags in the air chamber.
Painted
MM-161T with DCU-C171PP has come to be able to
play
a forceful low pitch sound from the
beginning of July
after about two
months.
Specifically, strings increased in thickness,
and started playing
in the
hard-core note such as a cello and a
bass.
And the position of a sound image localization
became clear, so I had
come to understand the movement of
each instrument
in an orchestra
perfectly.
I have even listened in
monotonous adagio
of the main constituent of strings, and
I became able to receive
an impression by its deep
tone.
I like a performance by Herbert von
Karajan, and have many his CDs.
His Josef Anton
Bruckner, 9 SYMPHONIES became popular,
but I
could not understand the reason.
I had the impression
that the brass are just noisy,
so I thought of
selling the CD.
However, the painted MM-161T with
DCU-C171PP played the CD
by a pyramid structure
supported by a deep bass, and does not
give me a feeling
of brass noisiness.
Introduction
Symphony
No.5
I was surprised when I listened to the first
pizzicato.
Finale
Symphony No.5
I was
so dumbfounded that strings, brass, continuous blow of
timpani
and a tremendous explosion of the
fugue.
Symphony
No.1
I thought the performance is wonderful,
too.
Strings collided with each other, and sang a
melody with eloquence.
It means that the painted
MM-161T with DCU-C171PP was able to
reproduce
the original music of Herbert
von Karajan
by its expressiveness.
It expressed a
low frequency range sound which could not to be
heard
until now, and the aspect of the music
has
completely changed.
I put down Corian board
under the painted MM-161T because it has excessive part
in high pitch sound of timpani.
Additionally, I put
felting into
the horn-opening area, I will adjust it
without having
adverse effect to a superb low pitch sound.
Effect of
aging and painting appeared after a lapse of six
months,
and it brings endless new discovery.
So, I am
exciting to listen to old CDs anew.
I got to
know Hasehiro horn system in an unexpected way, and
I have been able
to discover the new sounds thanks to Hasehiro.
You
reminded me of the enjoyment of listening the music,
so I
have to be appreciative of Hasehiro.
I am thinking
about upgrading to
MM-181T from the present MM-161T
in the
future.

Hasehiro replied that
the scale of the
sound increases
if you increase the layered boards
when I consulted
my MM-161T upgrade.
Moreover, I told that I like a direct
clear sound. Hasehiro replied,
"It has a rich atmosphere of
hall tone if you upgrade to MM-181T,
so I recommend that
you upgrade to MM-171T."
I bought one set of
MM-T layered boards for 2 channel and
the one pair of
the
SSC coated front
baffle boards in mid-November.
I painted the layered
boards in a same manner and hung
3 Lipton® tea bags in the air
chamber of upgraded MM-171T.
Always I feel nervous with
expectation and anxiety
when play the sounds for the
first time.
I made a comparison between the sound of
upgraded MM-171T and
the afterimage of the sound of the
previous MM-161T.
The sound hasn't reached the previous
grade.
A high band does not spread, and a low band has
excessive part
but it is lacking in depth.
I spread
black cobbled
stones over
the horn opening and inserted
a round
bar having 3cm
diameter as a measure
against excess of low pitch
sound.
Additionally, I put needle
felt for the
control of the low pitch sound.
"A MIDSUMMER NIGHT'S
DREAM"
Felix Mendelssohn
It's a balanced low
pitch sound!, but the left violin is lackluster
quality
even though a cello and a contrabass have a rich
tone.
The tweeter cord was unplugged from DCU-C171PP when
I checked
the air chamber of the left MM-171T.
It was
due to a simple reason. At the same time I confirmed
my
own hearing ability.
It is certain that the sound has an
overlap with my imagined sound.
A stage appears between
both MM-171T speakers.
There are violins on the left,
cellos and contrabasses on the right
and woodwinds in the
centre.
I can realistically feel that horns strongly play
from the left, and
trombones with contrabasses
respond from the right. |

The localization
of musical instruments is more excellent
when I
listen to chamber music.
I was so impressed that I
had goose bumps from a rich sound,
particularly
strings.
I can understand the foundation of orchestral
works well, and make
a new understanding when I listen to
a trombon and a contrabass.
Especially, string
orchestra entertains me with a fascinating tone.
I
introduced back loaded horn speaker for exciting hitting of
gran casa,
but I came to feel very good about a massive
tone of strings.
I am immersed in the pleasure of
listening music.
I pursued my own sound, and spent almost
one year.
Thank
you!

Thank
you.
My special order speakers were to arrive on
Saturday
and I immediately listened to it.
The
high-pitched tone was sweet sound and the low-pitched
tone
was a large sound.
This sound is
exactly what I was hoping for!
At first,
distortion noise could be heard
coming from the
high-pitched tone of SICA 20cm full-range.
But the
high-pitched tone of this PARC Audio woofer DCU-151W
is
distortion-free sweet sound from the
beginning.
DCU-151W
woofer
You
recommended SICA 20cm full-range when I asked you
to make
speakers of muscular bass.
Hence SICA 20cm
full-range is still ahead in dynamism
of the low-pitched
tone.
Midrange, DCU-151W woofer is very pleasing with a
gentle sound
than SICA full-range.
The passage of
the aging will lead to a change in the sound
of MM-161K
with PARC Audio DCU-151W.
The sound is going to be a
desired tone color. |

At the end of last
year,
I loved MM kit at first sight at Hasehiro event in
Ginza
and bought MM-161S.
It's getting warmer, I
painted my MM-161S for two weeks.
I cleared the gap of
the front baffle boards by retightening all bolts
and
primed the bodies by sealer.
After that, I faced the
bodies by water-based clear
lacquer and
black
lacquer.
Immediately I am listening to my favorite
jazz in today.
It's like I'm listening to live music than
ever, but might be
self-satisfying for
me. |
|
I'm really excited with MM kit, and it
made me feel young again.
I'm glad I discovered MM
kit.
I wish you continued success and prosperity for
your own business
more and more.

FE208ES-R
I'm T mounting FOSTEX
FE208ES-R on MM-1101T.
Already 3.5 years pass and it is
nearly done with the aging.
So I report on it.
In the
beginning, low-pitched tone didn't come out from
FE208ES-R,
so high-pitched tone was very noisy.
But
the noisiness is gone and the low-pitched tone came
out
by slow degrees.
Now I think it plays music with
balance.
Believing that alnico magnet plays
an invigorating sound,
so I bought FOSTEX
FE208ES-R.
It took 3.5 years, and it seems that my
desired sound
finally came out.
It is no wonder that
the aging takes many years to complete
because I listened
daily for only about 30 minutes.
Now the sound of my
MM-1101T bears comparison
with my sound criterion STAX
earspeaker.
At this moment I rarely use STAX
earspeaker.
Recently I went to Akihabara to listen to
the sound of B&W speaker
of JPY600,000 after so
long.
B&W is also my favorite tone quality, but
MM-1101T with FE208ES-R
is more than that.
It may be
said that MM-1101T with FE208ES-R is much better
than
B&W because the efficiency is far higher.
Anyhow,
MM-1101T with FE208ES-R plays a refreshing sound,
and has
high resolution.
It sounds like peeling a veil even
previously-heard CDs.
I suppose that the sound
localization and
spread of sound to the space are the
highest level
in full-range single driver
speakers.
But powerless amplifier may not drive FE208ES-R
because
it sounds like a sound ball when I connect
to
another inexpensive amplifier.
The amplifiers
affected by the back electromotive force may not
be
able to drive FE208ES-R because of high
efficiency.
I think maybe tube amp is more suitable for
FE208ES-R
because of low feedback.

Mr.suna-t,

I bought MM-141S
and DIY Audio SA/F80AMG through a dealer
the day before
yesterday.
A speaker driver is mounted to the
outside of a front baffle
in ordinary circumstances, but
I thought
to mount SA/F80AMG to the inside
because the
air chamber of MM-141S has enough space
and I can protect
the diaphragm.
And so I bonded all of the
construction boards of MM-141S
with a diluted bond yesterday.
I was thinking about
reporting the MM-141S with SA/F80AMG of you
after a
long listening time after being completely cured.
Despite
this, I allowed it to play music in a temporarily put
condition
even though the bond is half-dried.
I was
moved by the sound of MM-141S with SA/F80AMG and
I
have written my impressions now. |
|
a
temporarily put condition
MM-141S with DIY
Audio SA/F80AMG
|
|
I was charmed.
Musical
instruments are positioned behind the
MM-141S.
MM-141S with SA/F80AMG has a rich bass
sound,
and plays high pitch sound of strings of baroque
music beautifully.
Also it plays Keith Jarrett's
piano playing containing a glossy feeling.
In
addition, it has a sence of scale I can't believe
it is
only 8cm speaker driver.
I understood that
MM-141S and DIY Audio SA/F80AMG are sold in
sets
by the dealer.
Inside mounting of
speaker driver enhances its safety,
so I want to
recommend it to Hasehiro MM owners.
It can reduce
the volume of the air chamber of MM-141S, and so
it can
put the higher back load. < related owner
voice >
As a result, perhaps I can feel a
rich bass sound
although not a deep bass sound.
I
didn't use the accompanying needle
felting, I
made
absorption materials each having the form of
a
regular quadrangular pyramid about 4c㎥ using kitchen
paper
and
cotton
wool.
I have put 2 quadrangular pyramids
into the air
chamber of MM-141S.
I am hoping that the sound to be
improved by
further advanced bond drying of MM-141S and
aging of SA/F80AMG.
I am very happy about getting a
good buy.
I would like to recommend Hasehiro speakers to
my friends.

― Report from
Hasehiro ―
At the end of last month a visitor
brought me a unique speakers,
but they aren't a
loudspeaker;
rather, they are back loaded
experimental horns.
They are a U-shape back loaded
horns made of MDF
measuring about 1m in
length.
He focused its
attention on an air chamber.
Air chamber with the baffle
can be attached and removed easily.
The experimental horn
is excellent.
He had 3 differently-shaped air
chambers,
but they have the same capacity.
One is a
cubic shape, the second is a funnel shape
and the third
is a pointed hat shape.
I know that the quality of sound
changes with the capacity of
an air chamber from my
experience.
But I could clearly understand that the
sound quality also can change
by its shape and the
position of throat from this experiment. |
experimental
horns
|
The sound of a cubic air chamber
was relaxed, but a little stayed in it.
This muffled sound will disappear by the
insertion of
sound absorbing materials into the air
chambers.
Next is a funnel-shaped air chamber, it send a
sound
into the throat like funnel. The sound was very clear, but it is difficult to
expect bass.
The experimental horns can replace the
air chambers with others
at one-touch operation.
But I
couldn't make a detailed comparison of the three
sounds
because there was only one set of speaker
drivers,
it took too much time to replace the
drivers.
In the background, I liked the sound of a
pointed hat shape
if not want bass. It was
well-balanced sound.
In a sense, a funnel shape and a
pointed hat shape
are reverse back
loaded system.
Combine the concept of normal and
reverse back loaded system:
this is perversive
proposal, but it might be interesting.
Please try to
alter your MM kit if you are
interested.

― Report from
Hasehiro ―
I have been making PMP-151S mounting EMS LB6 for demonstration.
Before
its completion, I could complete
lacquered
MM-151SK with LB6 I had received the order.
Lacquer
finish is characterized by spreading sound gently.
I
chose the paint after hearing the
client's favorite sound quality. |
lacquered MM-151SK
with EMS LB6
|
I temporary mounted EMS LB6
on PMP-151S of cashew paint
and compared both
sounds.
PMP-151S with LB6 played big-boned dynamic sound
with
bright beauty color such as a piano and a
violin.
When switched to lacquered MM-151SK with
LB6,
the sound pressure dropped a little bit and it
lacked in dynamism.
So I was a little short with it,
but it's beginning to understand
what the charm
gradually.
Lacquered MM-151SK with LB6 expands the
acoustic field gently,
and it has a relaxing tone
unobtrusively.
The musics envelop the listeners in a
warm hug.
The client liked the sound by lacquer
finish.
And he says,That's high-class sound!
Sound
quality varies greatly depending on paint.
If you need
about completed Hasehiro back loaded horn speakers,
I
will choose the paint that suit your favorite sound
quality. |
