I have an Energy e:XL-S8 subwoofer 4 months old in perfect condition that I want to sell. The only reason I'm selling is I'm replacing it with an S8.2 because its on a shared wall in my apartment and I'm hoping going to a front ported enclosure will help with not annoying the neighbors as much. I'm Located in the Seattle/Tacoma Area in Washington. I'm asking $150 plus shipping or if local I can meet or drop off. This sub is a very good performer, rated at 100watts rms and 400 watts peak. Frequency response of 29-100hz, with a variable low pass filter at 50-100 hz.
