in-wall subwoofers are suitable for use in a wide variety of listening
environments. Note however, that room construction, dimensions and furnishings all
play a part in the quality of sound you ultimately achieve. Try to follow these guidelines:
a) Strong, rigid walls are preferred for best bass balance. For even better results we
recommend adding additional bracing and acoustic damping material to the cavity
prior to installation. See section on ”Subwoofer Installation” later in this manual for
more details.
b) It is important to note that just as the amount of soft furnishings has a decided impact
on mid and high frequencies, those frequencies below 150 Hz are dramatically
affected by the room itself—its size, shape, as well as the physical boundaries of
the room.
THE LISTENING ROOM
When considering subwoofer placement directly into a wall, keep the following in mind:
• DO NOT install subwoofers in a ceiling.
• DO NOT install subwoofers into lath or plaster—over time, the bass vibrations will
cause material to crack.
• DO NOT install subwoofers into cavities that contain ductwork.
• DO NOT locate subwoofers close to wall mounted fixtures that may vibrate (remem-
ber to check the other side of the wall too!).
• If installing in a wall with metal studs, make sure studs are securely fastened so that
they do not vibrate or rattle.
• Some acoustic bleed-through into the adjacent room is unavoidable. See section
on “In-Wall Cavity Preparation” for suggestions to reduce bleed-through.

in-wall subwoofers are designed to be used in pairs. Using a pair of
subwoofers will allow you to randomize the standing waves within your listening room
so that bass is distributed in a more uniform manner. Two subwoofers also ensures
even lower distortion, especially at high output levels.
Bass is less and less directional as it goes down in frequency. For best sonic
integration, placing one subwoofer in the wall at the front of the room and the other in
the wall or at the rear usually provides the best performance and sonic integration. If
this location is not possible, keeping in mind the guidelines provided earlier, you may
place your subwoofers anywhere in the wall without affecting the stereo image of your
front speakers or the soundstage of your multichannel speaker system.
