POWERED SUBWOOFER All M&K powered subwoofers have exceptionally sharp (36 dB/octave) low-pass filters to remove the midbass and midrange frequencies unwanted in a subwoofer. This makes your M&K subwoofer truly non-directional. No matter where you put the subwoofer, you must allow room for ventilation of its heatsink and backplate. The subwoofer's power amplifier is mounted on the backplate, and it generates heat. 1. Leave clearance around the subwoofer's heatsink. Do not cover it with drapes. 2.

POWERED SUBWOOFER The best way to set the level of the subwoofer is to do it by ear, listening over several hours or days to familiar recordings. Make adjustments to the level in small increments, depending on whether the bass level sounds too high or too low. Of course, you can always deliberately set the level higher or lower than flat if you need a higher bass level (especially for cinema or television sources) or if you don't want to disturb your neighbors. 5.

POWERED SUBWOOFER If multiple subwoofers are used, try to place them in the same location. Stacking is best, but you can also put them side by side. Alternately, you can put multiple subwoofers in different locations, at adjacent corners. This is appropriate when you have limited choices in locating the subwoofer and none of the available locations work well. Try to place multiple subwoofers at equal distances from the listening position to avoid phase cancellation. Wiring with two subwoofers is

Hum can also be caused by AC ground loops.
