FOSTEX F200A WCW-F200A
 

One month have already passed since came my home.
During this period, I have heard the sound day after day.
At first, for aging and then for check the sound.
Just blissful moment for me.
At the beginning, the low tone is inefficient sound
but as the aging continue, it has improved by degrees.

WCW is a lot of advantages, sound freshness, resolution performance
and so on but most of all, expressiveness of depth feel to backward
and forward in addition to soundscape to right and left.
Even 2ch stereo is high realistic sensation in the center of a hall.
Thank you for Hasehiro Audio.

FOSTEX F200A WCW-F200A

Three weeks have passed since came my home.
I tuned many variations on my own way.
During this period, I could feel really good quality of WCW
in any condition.
WCW has a great vibrancy-adjusted power of concrete.
In particular, I'm so moved by solo that I'm lost for words!

Arthur Rubinstein Chopin "THE NOCTURNES"
I melted my body and soul by the treatment of each note.

Now is a genuine-oriented era.
To your continued success.

FOSTEX F200A WCW-F200A

One week have passed since came my home.
I am enjoying the sound every day after work.

I simply can't believe it.
That's graceful and beautiful sound.
Each instruments sing without altering the tone color.
This looks a matter of course but the fact that it is a difficult matter.
Not only beauty the tone color of instruments but also waft a feeling of the air in a concert hall or jazz club.
I tried various audio until now but I have never been
in this realm before.
WCW sound: That makes someone happiness.

Finally, I say in conclusion "WCW is real one."
WCW is master's work with combined technology of audio nuts.
I must thank you for Hasehiro Audio.

 Mr.Y, Shibuya-ku, Tokyo 
 
September 2006
FOSTEX F200A WCW-F200A

I think this is a great loudspeaker.
I thought I will report the impression after attended more to musics.
But I immediately report the impression because I like that very much.

I've been looking for more wide range of
full-range speaker.
I was interested in WCW, too, b
ut WCW-200A
carried ALTEC 2way speaker 409-8E
so I've been obsessing for so long.
Under these circumstances, I knew the release
of a new WCW model; WCW-F200A.
So I placed order for WCW-F200A soon.

Concrete horn is my icon, and I wanted to use
alnico driver.
So I've been looking forward to
WCW-F200A coming.
I have arranged CAYIN KT88 push-pull amplifier.
WCW-200A
WCW-200A
I use SUNVALLEY tube D/A converter
through BEHRINGER digital parametric equalizer.
First time, I felt the high-tone range...?
The peak value of the speaker driver FOSTEX F200A is about 6dB
at around 4kHz.
So I adjusted the equalization of BW1/2 octave to -6dB.
As a result, it brought a good balance.
I thought that the low-tone range is enough because of
20cm full-range speaker but the high-tone range lacks something.
So I arranged the equalizer, but it stretchs ahead sufficiently.

Mainly, I listen to female vocal musics.
WCW's female vocal is fantastic, especially the expression of
the climax doesn't have my main system, WCW-F200A is the greatest.
The risetime of low-tone range is quick sufficiently,
and WCW has the merit of particularly full-range speaker
such as sound localization, etc.
Thus, I always turn up the volume more and more.
But I don't feel a loud sound even such a megavolume.
Because it is low distortion, I think.

It has only begun.
WCW-F200A may takes over the main position on my system.
Thanks for the best full-range speaker.

 Mr.K, Nerima-ku, Tokyo 
 
August 2006

Today, I received RR-10LC12S.
The beautiful speakers appeared in front of me when I opened the box.
The beauty of the color and the figure produce a sense of expectancy
to the sound.
At first it was broken sound but it was changing to the original sound.

Audiotic comment to the speaker is emptiness.
I can't describe RR-10LC12S in better terms than beautiful sound.
RR-10LC12S brings a level of excitement that I have never
experienced before.

RR-10LC12S is a terrific loudspeaker!
Please keep making RR-10LC12S in the future.

March 2006

I received RR-10LC12S.
RR-10LC12S was individual sound surpassing.
The high-tone range of over 600Hz have been cut
like through minus 12dB low-pass filter in obvious, but it consists
as music, it's amazing!

My body melt quickly when I put on the residual echoey recording without using a microphone at great hall.
The sound especially mainly low tone and midrange instruments
such as viola, cello and oboe.

Please listen to "Andras Schiff - Davidsbündlertänze"
when you have a chance.
Great!!
Please keep making individual speakers in the future.
Thank you very much!

October 2004

RR-10LC12S makes the most of what it had
at my listening room.

Now I use 4 different types of speakers such as
Zingali 95-206II Control Monitor (Italy), Infinity Kappa 9 (USA),
Technics SB-M1000 (Japan) and Hasehiro RR-10LC12S.

I mostly drive RR-10LC12S by
6F6 pentode parallel push-pull Olson type amplifier.
According to the circumstances, I drive it by LUXMAN pure class A or
Accuphase E-407, too.

The good thing about RR-10LC12S is a good sense of speed
and response.
So, I play it when I listen to piano music.
It has a narrow range, but I am unbothered by it when I listen to
piano works by Bach, Haydn and Mozart.

It may be no exaggeration to say that RR-10LC12S is for
Mozart's piano works.
Now RR-10LC12S is essential for me.

Baby Urbanized Horn Speakers  

 Mr.Arai, Saga Pref. 
 
May 2008
(the speaker drivers are custom-ordered
Vifa 10BGS 119/8)

Now, more than one month later,
UMU-131SS still has surprised me every day.

I know "live sound" since my college days
because of I was a member of a jazz band.
I had given up playing for "live sound"
Vifa 10BGS 119/8
10BGS 119/8
with aerial vibration of low-pitched tone of bass guitar
and bass drum until now.
In spite of that, UMU-131SS sends it without much resistance
and any stress from only 10cm drivers.
It was a big impact shock! There's no other word for it.

Nothing will change if I turn up the volume.
It has more energy but I don't feel a distortion.
UMU-131SS is good S/N ratio. No change the amplifier...
UMU-131SS doesn't play unneeded sound.
Conventional speakers make a loud noise when I turn up the volume,
but UMU-131SS is not.

Is the sound by infinite baffle?

I never say "UMU-131SS is perfect", but I can forget
about audio and enjoy music from now.
Finally, I got away from stress which lasted for about 35 years.
Thank you!

December 2007

UMU-131SS arrived at home.
Soon, I set up it on my desk.
My desk is good size for UMU-131SS, and I am very pleased
as a decoration.
I have heard the sound of PC and CD by digital amplifier.
I am surprised to filled pervasive realistic sensation from my desk
to my room, the resonant sound and low-pitched tone.

It has only been a few days since I started sounding UMU-131SS.
But it has improved the continuity of the sound between
low-pitched tone and mid-high-tone range.
And the sound came out to the fore much more.

UMU-131SS is really excellent product.
Please keep making UMU-131SS in the future.
Best wishes in your future business endeavors.

 Mr.Kumagai, Hyogo Pref. 
 
February 2007

I lived in an apartment when I married.
I couldn't bring in my big speakers in an apartment.
So I've used small speakers of my wife's all-in-one mini stereo.
The small speakers died by aged deterioration.
So I bought TIMEDOMAIN mini, and have enjoyed.

One day, I was browsing the magazine article about UMU-131SS.
One is the directional loudspeaker in contrast to TIMEDOMAIN mini.
Next, I had been interested in backloaded horn speaker from before.
Furthermore, UMU-131SS is only A4 size.
I bought UMU-131SS.

I put on a CD.
At first, the sound was imbalance between mid-high-tone range
and low-tone range.
Brushed away that as time passes.
I could understand high resolution performance
to mid and high-tone range soon.
Low-tone range is also high resolution performance as time passes.
It has only been 2 weeks since it came at my room.
I began to understand the high performance.

UMU-131SS has intrinsic value, and I am having a great time now.
Thank you for providing UMU-131SS.

 Mr.H, Nara City 
 
January 2007

After 3 months, I simply report. I bought UMU-131SS and
ONKYO BR-NX8 for HDD recording the baroque music
from FM station every morning.

I'm happy with UMU-131SS.
I could get stable low tone and amazing sound localization
from the beginning.
In addition, the low tone is rich and a sense of reassurance.
I think it's effect of the urethane coating.
Maybe the sound would be better if I choose SSC coating.
But that's enough to me.

Their combined cost is only about 100,000 yen.
They have reached high level in spite of the compact size.
So I have urged them to acquaintances.
I publicly proclaim that economic audio is intellectual challenge.
In the future also, please develop amazing products.
 

 
 Mr.U, Niigata City 
 
December 2006

Last month,
I bought UMU-131SS and tube amp for my subsystem.

The speaker is rather good sound.
Actually, I listened to the sound at Vacuum Tube Audio Fair.
The undertone gushes out stronger than main DIATONE DS-A7,
furthermore, the sound localization is wonderful.

I found out hidden sounds by UMU-131SS.
UMU-131SS stays in my main system, now.

 Mr.Takahashi, Taito-ku, Tokyo  
 
October 2006

I purchased SSC coated UMU-131SS in May.
I put UMU-131SS on my desk of the office and I heard jazz, rock
and Japanese popular music.

I was using AM-5‡V (BOSE) in my office until that time.
The sound of BOSE is artificial sound I think.
That is good to hear as BGM and the latest rock music
and popular hit songs but I did not like to hear the old jazz music
due to artificially-made sound.

In the daytime, I am using AM-5‡V for play music as BGM.
But I switched to UMU-131SS after staff leave office
and I hear jazz music.
UMU-131SS is unclouded sound in spite of compact body
and sings bass by high sound pressure.

 Mr.Arai, Shinjuku-ku, Tokyo
 
September 2006
"Please install A4 size paper in horn aperture into the horn opening.
That alone makes the undertone has changed a whole lot.
Once, I thought of making like the parts."


I made the extension horn for UMU-131SS based on your above advice.
UMU-131SS is the beauty of undersize.
So inevitably, it may be the only solution that I extend it forward.

The undertone became deeper and well-balanced sound
even lower the volume.
At first, I felt like horn flavor.
Consequently, I added the dark area of the picture.
It eliminated the flavor.
I measured the frequency characteristic,
the low-tone range surely increased, but the mid-high-tone range
was unstable condition.
Probably 
the standing wave in the extension horn had an influence
on the characteristic.
So I put
felt pad, as you will see in the photo.
It eliminated, too.

Despite that, the extension horn looks grotesque.
I can easily gather from look and feel that you didn't place it
on the market, but the extension horn is just attached by
double-stick tape to UMU-131SS, so I can detach it shortly.
Fortunately, I was really interesting and enjoyable.

Thank you very much.
The much-awaited UMU-131SSK arrived on Saturday.
As it turns out I took off my hat to UMU-131SSK!

Now, I am right in the middle of study for a promotional exam.
But I mounted Tang Band W3-583SA on UMU-131SSK impatiently.
I listened to it on my own bass reflex till now,
and was satisfied in its way.

But is it now?
The music level played by UMU-131SSK with Tang Band W3-583SA
is completely different!
First "The sound is beautiful" as the cliche goes such as female vocal,
strings, winds, and drums.
And best of all, it played good-quality double bass having presence,
it was my long inquiring theme.
Moreover, the individual sounds have power with depth,
so I can feel high realistic sensation.
And it is comfortable sound not causing fatigue.
A noteworthy fact is that I could find a new part not listened by
my own bass reflex with Tang Band W3-583SA.

I have experienced a lot of loudspeakers such as JBL 38cm woofer
and own 20cm backloaded horn speaker in my audio life.
And I made a modest payment for an amplifier and a player.
I wonder what they are all about.
I have a bit of culture shock!
Large speakers have a definite advantage,
but this small and little speaker played such a wonderful music.
UMU-131SSK with Tang Band W3-583SA took over the main speaker
replaced own 20cm backloaded horn speaker.
UMU-131SSK is formidable!
That sound is good! That looks good! The size is good!;
UMU-131SSK has three elements.
My wife also praised UMU-131SSK.

custom-ordered AMA-131SS
 

\ Report from Hasehiro \

The special acrylic see-through horn speakers requested by Mr.K.
Standardized AMA-131SS has DIY Audio SA/F80AMG or
Tang Band W3-1231SH drivers, but the custom-ordered AMA-131SS
has Vifa TG9FD drivers.
Furthermore, standardized AMA-131SS have clear acrylic side boards,
but the custom-ordered AMA-131SS have glass-colored
acrylic side boards.
I recommended Vifa TG9FD drivers, but glass-colored acrylic boards
were Mr.K's pressing request to us.

I previewed Avril Lavigne's CD before shipping.
I thought,
"Why didin't I listen to the sound of AMA-131SS with Vifa TG9FD...?!"
The special AMA-131SS suited Avril Lavigne's song or
"electrophonic modern music" perfectly.
 Clear-cut brilliant dried sound quality, it allowed English lyrics
to be heard more clearly.

I could hear tired CD like a new CD.
Pianoblack PMP-131SS has also Vifa TG9FD drivers.
But the sound quality is diametrically opposed to PMP-131SS.
That's brightly refreshing sound quality and boyish dried voice.
Sound character changes by the material and paint of enclosures.
Even so, Vifa TG9FD is Euro-tone even acrylic see-through horn (AMA)
and even pianoblack mirrored horn (PMP).
I recommend Vifa drivers, its reproduced music has a subtle charm.

About 2 years ago,
the young serviceman for our accounting software
bought AMA-131SSK (DIY kit).
He had absolutely no interest in audio, but he bought that in favor
with its beauty.

At first, he mounted FOSTEX FE-83E in AMA-131SSK,
but he changed to Tang Band W3-593SG soon.
A while later he changed again to Tang Band W3-583SA.
Then he changed to AUDAX HP080G0 once again.
That is a chapter of only several months.
At this time, he became an appreciative fine audio nut, but he still
couldn't completely satisfy with the sound.
Next he changed to the Vifa TG9FD.
He knocked 4 holes by a chisel because the original size of holes is
different in case of Vifa TG9FD.
In the end, he really likes that, so he still remains Vifa TG9FD
as AMA-131SS's drivers.

At that time, he came all the way to my company to report.
"It
became a fantastic sound when I changed to Vifa."
I replied
"That's the good news."
But I couldn't make the prototype through my default.
I wasted to his kind report.
I now realized I
rediscovered the fascination of Vifa TG9FD
for Mr.K's request.

Silver colored AMA-131SS arrived. (DIY Audio model)
I immediately heard the sound, and I felt hardish sound
for the first hour.
But it became a well-balanced sound soon, and they are best looking.
On this day, I spent listening to musics with initial aging
from the evening to midnight after a long absence.

After that, I am enjoying listening to musics with
switch the speaker back and forth between AMA-131SS
and my favorite own 80L bass reflex of DIATONE P610A (2 paralleling)
with Technics horn tweeter EAS-5HH17G for about 30 years.
Own bass reflex captured the title about mid-high note
because the aging was finished previously.
But AMA-131SS won the title about the dynamism of undertone
by all odds.
I look forward to the sound after completing the aging.

This time, I bought AMA-131SS because I wanted to know
about Hasehiro backloaded horn speaker and
for a brand-new high-vision TV.
Actually, I am considering to buy new main speaker to replace
the own 80L bass reflex.
My favorite musical genre is classical music, so I already decided
ELCY Electric LC-12S as the next drivers.
Please propose the most suitable Hasehiro backloaded horn boxes
for LC-12S.

That's my first impression of AMA-131SS, Thank you.

(He bought AMA-131SSK)

I soft-soldered Monster Cables directly to speaker drivers.
And I drive it by ONKYO sound board SE-90PCI
with marantz power amplifier SM6100SA.

I played Apple Lossless file on an iTunes.
"What...!?"
The low tone was a muffled sound, the vocal kept to oneself
and the high tone was gasping for breath.
"I really blew it..."

But that sound has drastically changed as the aging progresses.
"Great!" "Is this a PC sound?"
Unimaginable sound field from its size appeared.
The low tone became a sharp and a powerful sound
a little bit too much.
The vocal became a nice sound,
and the high tone became the sound moving across a space.

It is a lot of fun to feel the change of sound.
It has only begun.
By the way, I played compressed classical music by AAC 128kHz
but I just didn't think it's compressed sound.

I became a fan of Hasehiro, Thank you very much.

April 2008

It has been 3 months since PMP-131SS came to my house
in mid-December, 2007.

I feel simply pleasant speaker.
PMP-131SS is tight sound and it brings out the essence of the music.
Especially piano, guitar and vocal have a special feel.
I am using LUX38FD, that's good enough
from eight to nine of the tone knob.
I enjoy jazz, rock and J-pop.

No speaker until now, such a wonderful speaker PMP-131SS.
I started CRYSLER's small speaker.
Then, I changed JBL 4311BWX and used CELESTION SL6 together.
Next, I enjoyed the single cone of Ballad Ba404.
And now I reached Hasehiro PMP-131SS.

I wonder how long it has been since one has known Hasehiro Audio
in the information magazine
Tokusengai.
I would like to look at improve the sound quality for the future.
Thank you for your continued support.

 Mr.T, Hyogo Pref. 
 
March 2008

Some comments of owners and the stated features held
a strong fascination to me.
Especially in the article, everyone in town walks around fell
into the error of thinking that it's real violin.
I thought this is much-touted article because of
just 8cm full-range speaker.

I started thinking maybe...?
by a miracle...?

PMP-131SS concept is completely different
from conventional speakers.
PMP-131SS is like a time machine or Doraemon's "Wherever Door".

It's true that even good small speakers put on a performance
the realistic acoustic field to the listening room.
But it is just sound from the speakers.

However, PMP-131SS is completely different from that.
I am whisked to any concert hall or jazz club by space warp
in a moment when I put on CD.
I got a chill by "Hasehiro Pianoblack" over and over again.
I had my first taste of that through years of my audio life,
furthermore, at lower volume.

I just can't believe that.
I believe to the result of your excellent designing.
I got a fresh reminder of barriers such as network, deep woofer
and different texture tweeters to the real musical expression.

On violin solo, I believed it was impossible to a reproduction
by CD source.
And I think the right listening way puts full makeup on the violin solo
such as British speakers.
That ultimate is only "TANNOY ‡VLZ"
But PMP-131SS has completely and easily changed my sense.
I could realize the opening episode.

That's not loudspeakers.
That's magical black boxes, only tens of thousands of yen?

P.S.
I want to listen to the sound of PMP-131SS to musicians
and music lovers, not only audio nuts.
But maybe musicians and music lovers don't visit your website.

Thank you for your attention to my special order speakers.
The color tone of aramid fiber diaphragm stands out
against the pianoblack.

into high relief with a clear in silence.
I was drawn into the sound because they themselves sing it
wonderful and fascinating.

I had the following impressions when I listened to the sound of
PMP-141S with Tang Band W3-583SA.
"It has a shiny tone, especially as it left,
the sound left the sighful afterglow and died away.
Maybe the enclosures were still singing after that.
It is an embodiment of an instrument."

That PMP-141S is a crying speaker
with
a relaxing aroma
from harmonic
overtone, whereas
this PMP-151S plays
the sound with the original tone and
it sinks into the psyche of my mind
deeply.
This PMP-151S is a warm hi-fi speaker
with a superb audio performance.

I was under the impression that
the
sound of that PMP-141S is
the
pianoblack sound
until arrival of this
PMP-151S.
But I changed the recognition.

Listening impression by renting service
(renting service: in Japan only)


What a small speakers! They're really small.
I don't believe... They were playing music with energy
at that Hasehiro event...?
Usually, it seems larger when I bring it in my room when compared
with I saw it in a store.
But as for UMU-131XS, it's the opposite.
I think it's probably true to say that UMU-131XS is really small.

Well, I have the impression that the sound balance seems decidedly
high note-sided just slightly.
However, the undertone of UMU-131XS has a spark of greatness, sweeping away lack of bass expansiveness.

At any rate, the sound comes lightly and naturally!
UMU-131XS doesn't have a feeling of congestion of another speakers
of the same size.
Undertone like closed-box speakers doesn't come out
from UMU-131XS, it is soft sound like electrostatic speakers.
My sound image of UMU-131XS was active dry sound
when I listened to the sound.
Matter of compatibility with the amplifier? (my amp is ONKYO A-927)
It is a pleasant feeling to the sound image
in disregard of the existence of my room wall and UMU-131XS.

Of particular note is that it's great to listened to music
for more than 8 hours but not get tired!
UMU-131XS is delightful loudspeaker. Thank you very much!

Thank you for your hospitality the other day.
I like small things.
So I gave up the smallness and the chic-sedate-looking.
Unclouded pure sound like spring water pervades pleasantly.
The materialistic attitude is very strong after so long.

I took a photo UMU-131XS with my favorite WCW-2016R
mounted with Roiene RA160.
That sounds just like parent and child, doesn't it?
Sound inflection, emotion, atmosphere and expressiveness...
WCW-2016R is great, too. Thank you very much!

First, I was surprised the smallness
when I opened the shipping box.
Naturally, I knew the size but real UMU-131XS was smaller
than foreseen.
That's well-built speakers and very attractive
in solid black appearance.

I played the sound by my main audio system.
The CD player is Ah! NT4000 SuperbFV
and the amplifier is Ah! (PrimaLuna) Prologue One.

I made the assumption that the sound of backloaded horn is biased toward low tone.
But rather, the sound is fully provided for midrange.
Is backloaded horn contributing to ease the speaker driver?

The high-tone range has a little degree of surface roughness.
But it is no mean feat for the size of the speaker drivers.
Furthermore, my main audio system has a habit of
resolution emphasis.

The low-tone range is yielding disposition.
The midrange has a lot of dash, so I could listen comfortably
to vocal music.

Next, I played the sound by PC.
The PC is home-built AT compatible with M-Audio AudioPhile192 and
the amplifier is nonbrand-name small power amplifier (3W+3W).
I listend it up close.
So the sound had a tremendous impact.
I could listen enchantedly to pops and jazz vocals.

I want to have a chance that listen to
the sound of other Hasehiro backloaded horn speakers.
Very best wishes for continued success.

UMU-131XS
G750 JA0506 UMU-131XS
  

excerpt from his web page
http://homepage2.nifty.com/fukui81/album/Htmls_backload/UMU-131XS(1).html

I purchased UMU-131XS.
I wanted that when I listened to the sound
at previous Hasehiro event.

The left is famous FOSTEX G750
and the middle is YAMAHA tweeter JA0506.
UMU-131XS is just a little bit bigger than G750 about the height
and the depth.
UMU-131XS is really small backloaded horn speaker.

I match-up previewed G750 and UMU-131XS.
This is personal views.

FOSTEX G750:
I like this speaker from the very start.
That's brightly beat and the sound pressure level is a little bit higher
than UMU-131XS, I think.
That's 2 way but the undertone is a fool because of the small body.

Hasehiro Audio UMU-131XS:
The gamut is almost the same as G750, I think.
But that's much smooth
the undertone to the high-pitched tone
as may be expected of single driver.
And the sound has Hasehiro backloaded blood.
UMU-131XS isn't the speaker to hear sound, it's the speaker
to hear music.
The air of the horn opening begin to dance.

The sound of G750 plays from line connecting points of both speakers but UMU-131XS has rows of musical instruments
with an appearance of depth into
backspace line connecting points of both speakers.

March 2008

I received UMU-131XS.
I was very surprised to see the size of the package.
I immediately opened the package and I felt that UMU-131XS is
well-produced although small in stature.
Last night, I couldn't listen to the sound because of late-night return.

I'm listening to the sound since this morning.
I'm feeling the dynamism from the small speakers,
that no one can hardly ever believe.
It's rather nice to vocal atmosphere.
I'm looking forward to seeing the aging effect.
I will set up it in good condition, and I wanted to inform you of this
as soon as possible.

\ later report \

I can't listen to the sound on weekdays because of late-night return.
But I listen to the sound since morning on holidays.

UMU-131XS is at own best by gradation.
At first, it was hardish sound.
Now, it getting better to the whole connection and delicious sound.
I have great admiration for unbelievable formation of bass and
extent of the acoustic field from the size of UMU-131XS.
Mostly I'm listening to jazz, pop, classic, Tsugaru-shamisen, etc.
It's rather nice to the presence of female vocal.

UMU-131XS has enough realistic expressiveness.
Visual descriptions, large plectrum handling of Tsugaru-shamisen
and the fingering of a pianist.
However, UMU-131XS plays me with a refreshed feeling.
That's most impressive indeed!

I'm 50 now.
30-something years have gone by since I became interested in audio.
I had been eyeing Hasehiro backloaded horn speakers from before.
I was looking for small speaker to my room.

"This is it!"
I found UMU-131XS on the website and ordered.
UMU-131XS was excellent as I had expected.
Now, UMU-131XS sits on TV cabinet.
UMU-131XS properly responded to insulator and cable.
So probably it getting more better depends on the setting.

The atmosphere changed when I drove by tube amp.
I have been thoroughly enjoying the time.

 UMU-131XS
 

I was looking for PC speaker.
I was thinking about purchasing of BOSE CompanionR2 ‡U.

But one time, once I saw UMU-131XS, I thought that's the best size.
But how about the sound? \ What is this sound!
I fell head over heels, the size, the price, the shape and the sound.
I know I listened to mechanical sound until now.

The other day, suddenly my son said it is a beautiful sound.
I was surprised, my son still is 4 years old.
I enjoyed the occasion thoroughly with my son.
