Bought this from a reliable seller in 2005. It's missing the power plug. I never used it. Has been sitting in a box ever since. It had a sticker on the front. I cleaned off the sticky residue with Goof Off. That's why there's a dark smudge on the top of the unit.

The PSC-221 has been designed to accomplish two basic objectives:
1) Make the subwoofer sound like it’s in the front of the car (even when the subwoofer is in the back of the car).
2) Raise the perceived soundstage to ear level and solidify the center image (even when your front speakers are closer to your feet). Both objectives are accomplished by shifting the signal phase, primarily in the lower midrange frequencies, resulting in arrival time corrections to the sound from your front speakers. In a typical autosound system, the signal path is divided into different frequency ranges (subwoofer, midrange, etc.) as well as locations (front and rear). For best results, localizing your subwoofer to the front, you will need an active crossover sending only subwoofer frequencies to the amplifier running your subwoofers.
Specifications:
signal to noise ratio - >102dB
total harmonic distortion (1KHz) - .002% (this is unheard of with components currently on the market)
input impedance - 10k Ohms
input/output gain - unity
maximum input voltage - 8VRMS (very rare spec again)
maximum output (10K load) - 8VRMS
supply voltage - 11-15 VDC
Dimensions - 6.01" L x 5.125" W x 1.75" H
