Originally purchased in May of 2013 directly from Rythmik, this sub has been flawless in my system. I have since upgraded to a DIY 2-sub set up, so this guy needs a new home. Gloss black finish (excellent condition - it has been inside a cabinet for most of it's life) with black aluminum driver. Amazing sounding bass - clear, tight, and deep. Check out Rythmik's website for specs. Retails at $1448. Asking $900. Would prefer local pick up (willing to drive a bit to meet up). Located in central VA. Pictures available upon request.
