Thunderous bass response! That is what you notice right off with this speaker system. It is a 3 piece (2.1) set utilizing an 8" woofer with a long throw voice-coil and tuned port to further enhance the response. Our new flat panel type satellites with 2.5" super radiators balance the performance for a full audio spectrum response. A built-in 68 watt low distortion amplifier powers these drivers to their optimum range.
