Audison SR 6.600 Class-D 6-Channel Amplifier, 140W x4 + 185W x2 RMS @2Ω

Audison SR 6.600 is a 6-channel full-range D-Class amplifier engineered for modern OEM-integration and sound quality applications. Its compact chassis, high-efficiency topology, and flexible channel configuration make it ideal for 3-way active front stages, front/rear plus subwoofer systems, or DSP-driven multi-channel SQ builds.

Rated at 140W x4 + 185W x2 @ 2Ω, the SR 6.600 offers substantial power in a small footprint, supporting both traditional passive speakers and active system architectures. Low floor noise, clean gain structure, and stable low-impedance behavior allow the SR 6.600 to pair naturally with Prima, Voce, and Thesis-series speakers when used with Audison DSP.
