CONGRATULATIONS! Thank you for choosing your new Niles StageFront Home Theater Solutions™ Pro15SW 15-inch High-Power Home Theater Powered Subwoofer. With proper installation and operation, you should enjoy years of trouble-free use. Niles manufactures the industry’s most complete line of custom installation components and accessories for audio/video systems.

MUSIC SENSE AND 12 VOLT TRIGGER CIRCUITRY FOR AUTOMATIC POWER ON/OFF When enabled, the Pro15SW will turn on when an audio signal is present and remains on any of the audio inputs. The 12-volt System trigger input functions in the same fashion. Power will turn off when no signal is present after a delay of approximately 15 minutes for Music Sense or for the 12-volt trigger.
THE BOUNDARY EFFECT Placing a Pro15SW in a corner can powerfully affect the way a listener perceives bass response. Known as the boundary effect, a placement close to a corner-wall boundary will emphasize certain bass frequencies, while canceling others. This effect can make the Pro15SW sound excessively boomy and inaccurate to some listeners, while to others it just seems like more bass sound.
