RealSink™ technology logo.


Vertical, cast alloy fins dissipates heat effectively, without resorting to noisy fan-cooling.

Detailed Information

Many audio amplifiers rely on big lumps of metal that do a good job of storing heat, but not such a great job of getting rid of it. RealSink™-equipped JL Audio amplifiers feature real cast-alloy heat sinks with vertically-oriented fins. This design is far more effective than the lump-of-metal approach, utilizing the physics of convection and radiation to more effectively exchange heat with the surrounding air. This heat sink design was refined through extensive finite-element analysis, resulting in amplifiers that keep their cool under the most demanding conditions.
