6. Placement inside a cabinet or cavity: Since your AGA subwoofer utilizes our patented S2 bass loading
technology and is composed of an ultra-rigid cylindrical enclosure, you can place it inside of a cabinet or
cavity and still achieve outstanding performance without the “muddy” or “boomy” bass that plague
many subwoofers when located this way. Be sure to allow for ventilation, as the subwoofer amplifier
does generate some heat. Also be sure that the shelves and doors of the cabinet are solidly installed to
minimize rattles. Finally, there must be an opening from the cabinet to the room for the bass pressure
waves to exit the cabinet.
The Advantage of Using Multiple Subwoofers
All Anthony Gallo Acoustics subwoofers were designed to be used singly or in multiples. With a single
subwoofer, both left and right signals are combined (either at the subwoofer input or at the
receiver/processor output). With stereo subwoofers, the left and right low-frequency signals can be
reproduced by their own individual subwoofers. Stepping up from a single subwoofer to a pair offers a
much higher level of performance and provides up to four times the output level, for both movies and
music. Note: If your primary focus is listening to music, then a stereo subwoofer configuration can be
truly outstanding!
In addition to the above-mentioned setup for front-located subwoofers, some advanced home-theater
installations have begun to use one subwoofer in the front and one in the rear or along the side walls
of the room as described above. Locating the subwoofers precisely (the woofer cone should effectively
“split” the center line or quarter line of the room) at the center of the front and back or side walls
results in more accurate bass performance, enhanced sonic integration, and several good bass seats. If
wall center placement is not possible, locating the subs 1/4 of the way out from the corner along the
front and rear or side walls in lieu of 1/2 of the way also results in more consistent bass throughout the
room.
If All Else Fails, Try This…
1. Temporarily turn off all speakers (either by turning off the amplifier or disconnecting them).
2. Connect and place one subwoofer by moving your primary listening chair aside and placing the
subwoofer exactly where you normally sit. (Follow directions for connection, as outlined above.)
