Proficient’s IWS10 In-Wall Subwoofer is designed to maximize the
listening experience in a home theater or distributed audio system.
Reading this manual will help you understand the importance of
placement and crossover calibration, that the optimal balance of
volume, frequency response and dispersion can be achieved.
Placing the IWS10 within 3 feet of a corner in the room will result
in increased bass output at frequencies that may be desirable
for home theater use. Placement beyond that point will result in
smoother, more even bass performance, which is more suitable
for music. Ultimately, the best placement of the IWS10 subwoofer
is one that allows it to produce a neutral, uncolored sound.
The IWS10 is conservatively rated at 250 watts of power handling,
the frequency response 36Hz to 150Hz. (A 250-watt amplifier with
installer-adjustable crossover is coming from Proficient; dealers
will receive product information as it’s made available.)
It’s important that a quality amplifier-crossover combination be
used for precise detail and a smooth transition from the low fre-
quencies of the other speakers down into the sub-bass range. As
a Proficient installer, you’ll be able to preset the crossover for just
the right pass point.
When connecting the IWS10 to the LFE or subwoofer out of an
A/V receiver, follow the receiver manufacturer’s instructions for
crossover adjustment. The size of the woofers in the system’s front
left and right speakers will dictate the choice of the best cross-
over point in the receiver. The larger the woofers, the lower the
adjustment. When making the adjustment, it’s best to listen either
to music you’re familiar with or the test tones from the receiver.
However, in some receivers the selection of certain surround
modes automatically switches the crossover to a default point.
