HD750/1

Monoblock Class D Wide-Range Amplifier, 750 W x 1 @ 1.5-4 Ω


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 Ω, 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.

    Posted by David on 26th Jul 2020

    I upgraded to this HD from the JL Audio XD mono block and I’m extremely satisfied This HD amp powers a 10” W6 woofer and the sound that comes out of that woofer is very precise , clear and powerful. It is truly and upgrade to go from a XD to HD amp. 5 stars
