Pro-X Technology

L-RAE Motor Cooling Geometry

Pro-X features the L-RAE (Large Radial Air Emitter) cooling scheme, and is the first Earthquake product to do so. We had intended to use our patented TCT (Turbine Cooled Technology); however, TCT was developed for heavy, long stroke woofers and was not ideal for the quick, taunt and agile characteristics of the Pro-X woofer.

L-RAE is comprised of large unrestricted passages offering zero resistance to the moving air. A large drilled out pole piece with above spider side venting channels is combined with oversized radial cooling passages, matching the diameter of the voice coil.

This efficiently transports air around the voice coil and reduces the air resistance on the moving voice coil itself. The result is a remarkably capable cooling system that compared to a traditional pole venting scheme, reduces temperatures by 40 percent. All without adding acoustic artifacts or cost to the equation.
