If more traditional speakers are used, you may want to consider placing them
such that their output is scattered across the rear of the room. (See diagram.)
This placement provides a diffuse soundfield somewhat similar to the dipolar
speakers. Often, the best results will be obtained by placing them relatively high
and slightly behind the listener, cross-firing across the rear wall so as to create a
large number of reflections with relatively little direct sound arriving at the listen-
ing position.
Large rooms (in the 4000-6000 cubic feet range) have so much air to move that
they may benefit from having additional subwoofers for greater bass impact. The
AVP's subwoofer output can easily drive several power amplifiers—simply split its
output with Y-connectors. Alternatively, you can use one of your auxiliary chan-
nels to drive a separate, independently adjustable subwoofer, giving you true "ste-
reo" subwoofers.
Another technique for large rooms involves the construction of risers for the seat-
ing area in a dedicated home theater. Risers tend to enhance the visceral effect of
deep bass by providing a resonant platform for the couches and chairs, thereby
transmitting structural as well as airborne vibrations to the audience. This ap-
proach can be used alone or in conjunction with extra subwoofers. If both tech-
niques are used, consider building one or more subwoofers into the riser, which
both conceals the subwoofer's bulk and maximizes the vibrations being transmit-
ted to the listener's chair. (Action movies will never be the same....)
