placement
Unlike higher frequency sound, our ears have difficulty locating the source of deep bass sound.
Consequently, you have a fair amount of flexibility in where you place the subwoofer in your listening
room. We recommend placing the subwoofer at the same end of the room as the main speakers. Avoid
placing the subwoofer close to the main listening area or behind it.
The HT-series Subwoofer should be placed so its back is at least three inches away from the wall behind
it and all adjacent furniture a drapery. This is necessary for three reasons. First, it allows the bass sound
coming out of the ports to spread freely into the room. Second, it allows the amplifier to radiate the heat
generated by normal operation. Third, it allows clearance for the cable connected to the subwoofer.
Included with the C-series subwoofers are a set of four spiked feet. Using these spiked feet will stabilize
the subwoofer placement and may tighten up the subwoofer's sound. There are threaded inserts in the
bottom of the cabinet for these spiked feet.
The sound quality of your a/d/s/ subwoofer and how its sound blends with the main speakers is affected
by its location in the room and the settings of the rear panel controls. The bass output level of the
subwoofer is greatly affected by its placement in the room. As a general rule the level will increase as the
subwoofer is moved closer to the boundaries (the walls and corners) of the room. Corner placement will
produce the strongest bass and in some instances the smoothest response. Experiment with a variety of
placements that are practical and domestically acceptable. Try adjusting the settings of the subwoofer
phase and subwoofer volume controls in each room location you try. The goal is a combination of
placement and control settings that produces smooth solid bass that blends seamlessly with the main
speakers.
One trick for achieving the desired bass performance in a given room is to locate the subwoofer at your
normal seating/listening location. Then walk around the room while the system is playing. Look for a spot
in the room that is suitable for the subwoofer and where the bass sounds the best to you. If you then
place the subwoofer at that location, the bass response at your normal seating position will be the same.
Another consideration when selecting a location for the subwoofer is required audio signal and power
wiring connections. Because long cable runs can degrade a sound signal, the subwoofer should not be
too far away from the other components of the system. Plan for routing the connecting cables where they
won't be stepped on or crushed.
The powerful bass sound energy produce by the a/d/s/ subwoofers can cause objects to vibrate or rattle.
Setting a compact disc player on the subwoofer may result in tracking problems or data errors. Purely
electronic equipment, such as amplifiers or receivers are not likely to be affected by the subwoofer. Never
set up a turntable near the subwoofer. This can produce severe acoustic feedback.
