The SD and 4D series are full-range, multi-purpose amplifiers designed for dynamic and clean audio reproduction. A sophisticated circuit design combined with top quality materials have resulted in refined audio quality and superb transient response, backed by rugged reliability.
High power subwoofers are highly demanding on amplifiers.
The Stonewater B series of amplifiers have been specially optimized for high power bass applications.
The B series feature high power density that allow for the deepest of bass notes to be reproduced with maximum fidelity. Heavy duty supply sections ensure that the amplifier is able to deliver high power levels for extended periods and not run out of breath. To add additional stability, each channel has its own independent and dedicated power supply.
