A high current 200 watt (430 watts peak) amplifier is combined with a 12" long-throw driver containing a long-life butyl surround. Venturi vented to eliminate port noise often heard while listening to demanding videos. Unsurpassed performance at its price. The V1220 also features adjustable crossovers, automatic signal sensing, high level inputs as well as both Dolby Pro Logic & Dolby Digital/ DTS inputs.
