Monoblock Class D Wide-Range Amplifier, 750 W x 1 @ 1.5-4 ohms
This ultra-compact monoblock amplifier employs our Single-Cycle Control switching design and R.I.P.S. technology to deliver 750 W of clean power into any impedance between 1.5 and 4 ohms, giving you the highest degree of flexibility in designing your subwoofer system. Tight power supply regulation keeps distortion down and maximizes your bass quality. From a pure sound quality perspective, we invite you to compare the real-world, in-car performance of this amplifier to any other amplifier on the market, of any type, at any price.
While targeted primarily to subwoofer applications, the HD750/1 is a wide-range amplifier and can also be used to drive high-performance mid-range speaker systems.
This amplifier features a brushed aluminum finish with black powder-coated cast alloy heat sinks and bottom panel. A black powder-coated, gasketed cover is also provided to protect the controls.
