The Rythmik Audio FV15HP subwoofer sports a 15" high excursion servo controlled driver mounted in a large vented box with a powerful 600 watt (continuous output) rated amplifier. Powerful, rich, deep and solid with true 20Hz extension is how I would describe the bass output of this sub. Rythmik Audio has a very talented engineering staff that produced a truly great high caliber subwoofer product at a very affordable asking price. I would recommend a pair of these subs for any upscale home theater environment where seat to seat bass consistency and ultimate output are paramount concerns. It's loud, clean, and fast... and for most - that's going to make this an extremely hard sub to beat.
