I'm getting a signal on it, but it is far from the performance I'd expect from it. I've double checked all my wiring, and it looks fine. The Polk PSW450 at half-gain sitting in my room plays substantially louder than the SVS maxed. Here's the setup: Onkyo TX-DS494 to RCA cable running from sub pre-out to RCA/.25" mono converter to Channel 1 on Samson S700 (stereo mode) to ~ 10 ft. 16 gauge Home Depot speaker wire to 20-39CS (sitting in a corner) The room is 12'x14'. TIA for any help/suggestions!
