D-SONIC Custom Audio has designed and manufactured premium Class D power amplifiers since 2006 from our facility in the United States. Our M4 Series represents two decades of refinement in high-efficiency, audiophile-grade amplification, delivering reference-quality sound in compact, lightweight chassis designs that run cool and occupy minimal rack space.
The M4 Series spans four product families: stereo amplifiers from 400W to 3000W per channel for two-channel music systems, mono block amplifiers for dedicated subwoofer and channel duty, multichannel amplifiers ranging from 3 to 11 channels for home theater and distributed audio, and custom hi-power builds for extreme power requirements. Every amplifier uses military and medical grade wiring and connectors, ensuring decades of reliable service in demanding installations.
D-SONIC amplifiers are built for discerning audiophiles, home theater enthusiasts, and professional custom integrators who demand reference-level sound quality without the bulk, heat, and energy consumption of traditional Class A/B designs. Our Class D topology delivers power efficiently, producing minimal heat and occupying a fraction of the rack space of equivalent Class A/B amplifiers while maintaining full-bandwidth, low-distortion performance.
Each amplifier is hand-built and individually tested, with custom channel and power configurations available on request. We offer a 30-day in-home trial and a comprehensive warranty, reflecting our confidence in the M4 Series. Optional rack shelves and rack wings allow seamless integration into any standard equipment rack.
Whether you are upgrading a two-channel music system, building an immersive home theater, or powering a commercial installation, D-SONIC M4 Series amplifiers provide the power, clarity, and reliability that define premium audio reproduction.
