JL Audio HD class

Our flagship amplifiers feature Single-Cycle Control switching technology and R.I.P.S. power supplies to deliver top-flight audio performance. “Small” is not the only story here. Making a small amplifier is great, of course... but not if power and sound quality are sacrificed. This is why our engineering team focused on achieving world-class fidelity first, and then on making our HD amplifiers amazingly powerful, efficient and small.
