"The Cleanest Loudest Bass. The EP600 plays louder than a live performance at Carnegie Hall - an amazing 122 dB! Don't worry about distortion - the Intelligent DSP won't allow it. Instead, it tightly controls the signals to the 600-watt power amplifier and massive 12-inch aluminum driver and its dual 3-inch voice coil to provide you with peak performance, never going over the edge into distortion. Crank it up - XLF makes the EP600 unbreakable! "
