Description:
The idea behind the new B23 speaker line was
to
build
a
truly
high
performance
loudspeaker that could be retrofit in a wall.
The B23 not only has a stunning look, but
also has stellar performance.
In order to produce a Tru high fidelity full
range speaker, a three way design was
selected. A three way design allows the use
of the proper size component for each band of
frequencies for playback.
At the high end of the frequency spectrum, a
Titanium diaphragm tweeter was selected for
a Tru-to-life dispersion pattern that most
closely resembles the way natural sound
moves. This tweeter material allows the
tweeters to be played at the proper level,
without
the
listener
experiencing
ear
fatigue. This is especially important for
the high volumes at which home theater
playback often occurs. Also, the tweeter's
neodymium motor was selected because it
allows the tweeter to be compact enough to be
in a swivel mount. This allows the installer
to place the speaker where it would go in a
real world application, but also aim the
tweeters so that the listener experiences
them on axis where their response is best.
A 6.5" carbon fiber midrange was selected
because of its balance of the many factors
that must be considered when choosing a
midrange driver. This single piece cone has
good dispersion in the usable band. Also,
the cone size was important in considering
cone breakup, which is a form of distortion
that occurs at lower frequencies in larger
cones. The woven carbon fiber cone material
was chosen because it is very stiff, limiting
cone breakup in the usable band. It is also
very light, which helps reduce the weight of
the moving assembly. By balancing these
qualities, a midrange speaker was produced
with good dispersion in the usable band with
very little breakup, and is sensitive enough
to
have
incredible
dynamic
range
and
accuracy.
Because this is a three-way in-wall speaker,
the limited depth would not allow the use of
a conventional woofer driver. The solution
was to use three 6.5” woofers instead of a
single 10" woofer. This would give the
necessary output to balance with the rest of
the system, while playing low enough to be
truly full range, all while maintaining a
depth that still fits in a standard 2 x 4
wall.
This high performance full-range loudspeaker
needs the retrofit able back box in order to
control the amount of air the speaker
operates in, sold with the speaker. The
midrange speaker has its own enclosure
integrated with in the speaker to optimize
its performance and control its resonance.
The B23 cabinet is designed to allow the
woofers the exact amount of air space they
need to balance their output perfectly.
It is very difficult to get true full-range,
high quality sound out of a speaker that fits
in a standard wall. This is a problem the
industry has been struggling with for years.
The B23 series has accomplished this: Tru
high fidelity in the wall.
