8 QSC, LLC / AcousticPerformance™ Series Loudspeaker Application Guide
Rectangular rooms
If you need to cover a rectangular room evenly with four (or multiples of four) identical
subwoofers, consider placing them at the middle of each wall. Studies by Drs. Floyd
Toole and Sean Olive have demonstrated that this approach yields the most uniform
sound coverage and best mitigation of standing waves.
Application examples
Bar with dance floor
This first example is a bar with a dance floor. Obviously, they need a high-impact audio system to deliver music for the dancing
patrons. Four yoke-mounted AP-4122m loudspeakers and a pair of AP-212sw subs fit the bill. They’re all driven by a single
QSC CXD4.5 amplifier, using preset F13 and loudspeaker profiles selected to exactly match the choice of loudspeakers and
subs.
