Eminence Kilomax Pro-18A

The Eminence Kilomax Pro-18A is an 18-inch speaker designed to provide excellent performance in professional audio subwoofer and woofer applications in larger vented or sealed enclosures.

The Kilomax Pro-18A’s unique axially-located heat sink removes excessive thermal buildup from the critical voice coil area, which contributes to the driver’s 1,250 watts RMS power handling capacity. Not recommended for horn loading or scoops. Made in the USA.

Designed for high power applications in main PA systems and sub-woofers, there is nothing that shakes the house like a KILOMAX. A massive 109 oz. cast frame magnet structure, double spider suspension, and integrated front loaded heat sink all combine to pound out whatever you pound in.

For esoteric high power bass applications.
