Product Details

Celestion 18" Cast Frame Professional Woofer 8 Ohm

This cast aluminum frame 18" OEM bass driver from Celestion was designed in Great Britain for use in high-end bass speakers. The motor features extensive ventilation, a bumped backplate for reduced voice coil "bottoming out" conditions, and a vented pole piece for minimum power compression. A non-pressed, Kevlar-loaded paper cone is mated to a treated cloth accordion surround for increased sensitivity without sacrificing durability. Nickel-plated, spring-loaded terminals provide a quick, sure connection.

A relatively flat frequency response up to 3,000 Hz makes this driver well suited for use as a woofer in high output three-way HiFi home audio systems, and easy to cross over to a midrange. Additionally, the 97 dB sensitivity of this driver allows it to be used for professional audio, live sound three-way speakers; great for DJs too! 5.5 mm of Xmax are on tap to make this driver a great subwoofer! Factory buyout, limited quantities! Compares to speakers at twice the price!

Note: For best bass response, install this 18" woofer into a 10.5 cubic foot cabinet tuned to 38 Hz with two 6" diameter ports that are 4.25" long. Alternatively, you can also use a smaller 7.5 cubic foot cabinet tuned to 45 Hz with two 6" diameter ports that are 4.5" long.
