■If you like listening to music in surround modes (which emulate concert hall acoustics), consider using more than two surround loudspeakers to provide an extraordinary effect. With StageFront loudspeakers, it is easy to add another pair without affecting the decor of the room.

If the StageFront FX loudspeaker is being installed in existing construction, please use the included cardboard template to mark your installation location. Check for proper clearance within studs or any other obstructions before cutting the speaker opening. If you are unsure of the correct installation techniques, please consult your authorized Niles Audio dealer.

THE BOUNDARY EFFECT

Placing a loudspeaker in a corner can powerfully affect the way a listener perceives bass response. Known as the boundary effect, placing loudspeakers close to

a wall/ceiling boundary or near a corner-wall boundary will emphasize certain bass frequencies, while canceling others. This effect can make the loudspeaker sound excessively boomy and inaccurate to some listeners, while to others it just seems like more bass sound. As a good rule-of-thumb, if you like listening to your current pair of loudspeakers with the bass turned up, you’ll enjoy corner placement. However, if you listen with the tone controls at neutral, try keeping the loudspeakers at least 2 or 3 feet from the boundaries of the room.
