Box-Design Amp Box S2

The Amp Box S2 is designed to deliver room-filling sound to almost any loudspeaker.

Despite its small dimensions, the Amp Box S2 delivers sound characteristics similar to that of a tube amplifier, with a rich musical performance and a touch of analogue warmth. The advanced amplifier modules used are highly efficient, easily driving almost any loudspeaker with almost no energy wastage.

The small size makes Amp Box S2 easy to place in any living space. Partner with a Box Design S2 (or any other) pre-amplifier by the RCA inputs and build a compact hi-fi system that delivers a premium sound. The 12V trigger input allows the amplifier turn on in tandem with the Pre Box S2 Analogue, while the Trigger Output allows for bi- or even tri-amplification systems. The isolated speaker terminals provide a solid and reliable connection to your loudspeakers.

Housed within the improved S2 chassis, the Amp Box S2 is a premium device that belies the price.
