Story |
Hasehiro listening room's
regulars had asked Hasehiro for 2.5
years, "Hasehiro Audio has a variety of different UMU/MM
back
loaded horns for 5cm to 20cm, but the horn for
20cm is only
MM-191T. MM-T types are too heavy and too big, so I want you
to
design and make a middle class horn with a height of
about
600mm."
Hasehiro gave a favorable
reply to them, "Sure, I'll
design the
middle class horn at odd
times."
But Hasehiro was disinclined to it
because Hasehiro Audio had
focused on compact
horn speakers and there is no place to put
the
half-finished parts in a warehouse though medium
size.
So Hasehiro replied, "when
spring arrives..., after summer
passes..., once the new
year comes..."
One day, one of the regulars
got impatient and brought Hasehiro
a pair of Audio
Nirvana, "I entrust you with the
Audio Nirvanas,
so please make the backloaded horn
enclosures in a hurry.
Other two regulars will purchase the
same enclosures
surely." |

Home of JAZZ |
Hasehiro thought
that I have to make
the backloaded horn
enclosure
because everybody is really
enthusiastic about
the middle class
backloaded horn
loudspeaker.
In the spring of
2014, Hasehiro
restarted the design for
the
suspended horn, and completed it
in one
sitting.
Understandably, it is
newly-designed
exponential curved horn by
an elaborate
calculation.
Forthwith Hasehiro made the
back |
 |
loaded horn enclosures based on the design by way of trial, and
temporary
mounted Audio Nirvana Super 8" Cast Frame
received
from the
regular. Now, what sound is coming?
Thick sound got out from
the newly-designed exponential curved
back
loaded horn.
A bass tone of double bass
resonated to my bowels despite
temporary mounting, and
also, it played a roaring bass tone of
saxophone with
very heavy sound.
The newly-designed exponential
curved horn is shorter than the
horn length
of MM-T types,
so Hasehiro used to worry about its
bass tone, but it
exerted the desired performance.
Hasehiro narrowed its air
chamber compared with MM-T types, so
the brassy treble such
as hi-hat is just like live sound and texture of
the
metal itself. It is pleasing to the ear.
Hasehiro had
conviction that jazz listeners love the playing of
the
newly-designed exponential curved horn with Audio
Nirvana Super
8" Cast Frame from the home of
jazz.
Hasehiro rounded the corners of the middle class back
loaded horn
enclosures in design, and named it
UMU-191M. |

Unexpected Order from A
Celebrated JAZZ Critic |
At the end of 2014,
Hasehiro Audio had trial listening event at Jazz
cafe bar
MEG in Tokyo.
Hasehiro prepared UMU-131XS, MM-141S and the middle class back
loaded horn
UMU-191M with Audio Nirvana Super 8" Cast Frame for
the
event.
A celebrated jazz critic and the owner of
MEG, Mr.Yasukuni
Terashima came into MEG when playing jazz
after setting.
Mr.Terashima loved the playing of UMU-191M
soon after listening.
Mr.Terashima said, "This is very exciting sound! I
will get this!"
Hasehiro took it as a joke, but
Mr.Terashima said,
"There are
ever so many loudspeakers of good and beautiful
sound,
so they play bland sound to me, but this middle
class back loaded
horn plays sound I didn't know. That's
very fun sound! It shows me
sliding sound of snare drum by
wire-brush, and is worth buying with
just that.
But please paint
it Lamborghini yellow because I don't like
this color,
and I dislike the vertical lines,
too."
Hasehiro really got the
order from Mr.Yasukuni Terashima.
Hasehiro was quiet
confident that Mr.Terashima loves the playing of
the
UMU-191M with Audio Nirvana Super 8" Cast Frame, but he
had
no idea that Mr.Terashima purchase
it.
The UMU-191M was recognized and assessed as a
loudspeaker of
playing jazz by a celebrated jazz
critic.
Hasehiro kicked off the trial listening event with
a sense of
exhilaration at the capacity cafe
bar. |

of his speaker from

The Name is For Jazz
Audio Fans Only |
The first part of
the trial listening event is the UMU-191M.
Hasehiro
put on jazz CDs brought in by visitors one after the
other.
"Great!
midrange and treble jump out!"
"The quality of tenor saxophone played by
Sonny Rollins
is
great!"
| The facilitator chose a visitor
and sought the opinions, "I thought
that the
middle class backloaded horn speaker is no good
when
listened to the first music. But it is playing the
excellent jazz from
the second music. I think this speaker
allows the recorded
condition to be heard clearly.",
the visitor said. |
|
 |
The facilitator said, "Everyone is
really charged
up today.
Is there anyone who can speak
evil of the
speaker?"
A celebrated jazz critic,
Mr.Yasukuni
Terashima said,
"Please don't say the bass, or the
treble
about this.
The speaker is of much
value just
hear the sound of snare
drum!
Surely, the middle class back |
loaded horn speaker plays sound I didn't
know. I met exciting
loudspeaker for the first time in many
years."
|
|
Hasehiro requested the
nicknaming of the
UMU-191M to
Mr.Terashima, but refused once.
Visitors
said, "I think that it is
Terassie." "How about
Jazzload?"
Probably, Mr.Terashima
was
inspired by them, and said, "How about For Jazz
Audio Fans Only?"
The nickname was
decided.
UMU-191M with Audio Nirvana |

Super 8" Cast Frame will be called Hasehiro
