The Amp Box RS Mono is Project's high-end Box Design amplifier model. This highly impressive mono block amplifier provides impeccable sound staging, complete with pin-point accuracy of even the most subtle dynamics. An astonishing resolution is achieved, with the mono block's high-power output and 2 ohm capability, an ideal solution for bi or tri amping applications. 

The Amp Box RS Mono is an ideal companion for the company's Pre Box RS, and when combined with this component will offer a pure sound experience, that will live up to and even exceed the high standards of even the most demanding of audiophiles at this exceptional price point. Due to it's heat emission, the luxury casing of the Amp Box RS Mono should not be combined with Box Design Acryl
