The new & improved Symphony amplifiers are packed with even more power density than the highly renowned originals!

Introducing the version 2, bass-only optimized model of the S1, dubbed the S1v2.
The S1v2 does even more power than the S1, in a slightly larger frame. It is designed to be an absolute top choice for a subwoofer monoblock amp at this power level. Where as the S1 is a full range model, suitable for subwoofer duty or midrange/midbass, the S1v2 is designed and developed to be as efficient and stable as possible for subwoofer-only duty.

The S1v2 is rated for 1650w @ 1ohm
