of-phase with the direct sound. This can weaken or even cancel the sound. Keeping the distance between the subwoofer driver and any adjacent walls no longer than 1/8 of a wavelength (20 in or 51 cm at 80 Hz) can minimize interference.

Room resonance is caused by the reinforcement of certain frequencies between 20 Hz and 200 Hz, which creates “standing waves” or room modes. These resonant frequencies are determined by the dimensions of the room. The bass response is sharply boosted for a narrow band

near resonance, and then appears to be attenuated between resonances.

Corner or Center Placement

Placing the subwoofer in a corner (corner loading) excites the most room modes in the room, which tends to smooth the individual peaks and dips caused by each standing wave. Moving the subwoofer outward from the corner along the wall results in fewer standing waves, but may result in noticeable peaks at certain frequencies.

Some people prefer to place the subwoofer between the left and right main speakers, so that all the sound is coming from the same plane. Some prefer to use two subwoofers and place one with the left speaker and the other with the right speaker.

Another benefit of corner placement is increased efficiency and lower distortion. The energy that is reflected off the walls
