18" Cast Frame Driver, 8 Ohm, 1250 Watt

Eminence's Kilomax Pro-18A 18" speaker is 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. 7-year manufacturer's warranty!
