    Earthquake Sound Corporation, is proud to introduce a whole new breed of home audio power amplifiers.

    Companies claim that they have room correction built into their amplifiers, which in fact is only level adjustment by volume. Earthquake Sound's XJ line of amplifiers deliver the tools you need to correctly adjust a room to precision audiophile status.
    Most amplifiers use a simple equalization method that does not correct a rooms "phase" related problems. Earthquake's new XJ amps have true room correction that take into consideration: time/reflection and refraction. These new state of the art amplifiers first fix arrival time then equalization. While others try to equalize rooms by adjusting the volume/ can they call that room correction? The new 99% efficient XJ earthquake amplifiers address the actual phase correction problem along with the room EQ.
