Description
HD-Series Monoblock Class-D Wide-Range Amplifier, 750-Watts x 1ch @ 1.5-4-Ohms
This ultra-compact monoblock amplifier employs JL's Single-Cycle Control switching design and R.I.P.S. technology to deliver 750W of clean power into any impedance between 1.5 and 4Ω, 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, JL invites 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.
