Eminence Kappa Pro Bass Speaker (800 Watts, 18")

Eminence Kappa Pro Bass Speaker (800 Watts, 18"), 8 Ohms, Side

Great for subwoofers, three-way PA enclosures, or high-power bass guitar amps, the Eminence Kappa Pro 18LF is a low-end monster in a light, aluminum chassis.

Overview

The Eminence Kappa Pro 18LF is the latest addition to the popular Kappa series of drivers that provides tons of low frequency output in a lightweight, durable cast aluminum chassis. Use it as a subwoofer in small to medium sized boxes, a woofer in large three-way PA enclosures, or as a high-power bass guitar woofer. The 1,600 watt program power rating makes it an easy choice for new box designs or as a replacement for many single and double subwoofer cabinets.

Jerry McNutt, Product Design Manager at Eminence, commented "The 1,600 watt program power rating will give you the confidence to crank them up. The Kappa Pro 18LF is well-suited for new projects, and works well as a replacement for many single and double subwoofer cabinets."
