Understanding Subwoofers

Before we get into finding a location for the SUB-1500 and making any connections, we want to be sure we explain some fundamental principles about subwoofer performance. Simply hooking up a subwoofer to an audio system like a loudspeaker can significantly compromise the performance of the subwoofer, and at times even make the system sound worse. Below are some important guidelines regarding subwoofer installations that can help you get a better sound in less time.

Room Acoustics

The low frequency response and efficiency of a subwoofer are heavily influenced by the acoustics of the playback environment. More specifically, the response is influenced by the room's dimensional ratios, types of construction and location of the subwoofer within that environment. You can significantly improve the subwoofers in-room response and efficiency by experimenting with various room placements until you find an optimum location.

General acoustical guidelines to be kept in mind:

•Every acoustic space is unique and experimentation is an important key in finding the best possible location in your particular environment.

•A subwoofer becomes more acoustically efficient (has greater output) as you move it closer to a room surface (e.g. wall or floor).

•A subwoofer will give maximum output and maximum acoustic excitement when it is located in a corner.

•Under certain acoustic conditions, corner locations are optimum; in others, they can excite multiple "room modes", producing "muddy" or "boomy" sound.

Localization

A subwoofer generates tremendous energy, so it may vibrate objects close to it. If you hear buzzing or vibrating objects, make sure to try to dampen those objects. Rattling, buzzing and other sympathetic resonance can make a subwoofer's performance localized. This localization of sound usually prevents a full-toned, full-spectrum sound, and therefore should be avoided. Many times localization can be heard through surface vibration, but using a sine wave generator is probably the most accurate method.
