Earthquake Sound XJ-600R amplifier

Earthquake Sound’s XJ line of amplifiers delivers the tools you need correctly adjust a room to precision audiophile status.

Companies claim that they have room correction built into their amplifiers, which in fact is only level adjustment by volume. Other companies 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.

The XJ line consists of two high performance power amplifiers: XJ-300R: 300 Watts and XJ-600R: 600 Watts.
