The Kappa Pro 18LF 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.
Ideal upgrade for Mackie SRM1801 and the Harbinger HX118S. Direct replacement for B-52 18-180L.
Works well in vented and horn-loaded boxes.
