Featuring a 4” voice coil, an 18” Celestion® cast frame woofer produces thunderous low end with defined articulation. A convection cooled, 1000W Class-G amplifier, features a stereo crossover with high pass outputs, clipping protection, thermal limiting, and an integrated BBE® Sonic Maximizer. Connect any full range cabinet to the balanced High-Pass outputs and process your entire system through the BBE˚. Add any ACTPRO-12, ACTPRO-12M, or ACTPRO-15 atop using the 1.5” diameter pole mounting cup and optional 22” mounting pole. Accented in a durable, black HiFiDeco painted finish, the 3/4” birch plywood construction produces tight low end. Detachable 3” casters are included for easy load-ins.

PETP-Film diaphragm compression driver

• Sophisticated computer modeling was used to optimize the magnetic and acoustic design of.
these ferrite magnet compression drivers to achieve outstanding performance and reliability.
• A matched wave front phase corrector produces a perfectly coherent sound wave at the horn throat, for a detailed and dynamic mid and high frequency performance.
• The polyamide-insulated, copper-clad aluminum voice coil is edge-wound on a glass fiber former resulting in lower distortion and superior power to weight ratio.
• A one-piece, PETP film diaphragm and surround optimizes energy transfer for greater efficiency.
• The unique patented clamping system contributes directly to low distortion performance while improving the lower mid-band response.
