Subwoofer Reviews

Test Bench
Peak Output Measurements Peak output was measured using a UMIK-2 along with REW. Amp volume was turned to max and all measurements were taken with the UMIK-2 facing down 90 degrees at exactly 1 foot from the center of the woofer placed in the middle of my room to minimize the room effect on the measurements.

The volume level from my pre/pro was increased in 10 dB increments until distortion occurred while playing a 10-300 Hz sine wave. From there, the volume was dropped in 1 dB increments until distortion was no longer present.

You can see the output rolloff begins just above 30 Hz.
