Celestion 15" Professional Woofer 8 Ohm
This 15" OEM bass driver from Celestion was designed in Great Britain for use in compact, high-end bass speakers. The vented ferrite motor features a bumped backplate for reduced voice coil "bottoming out" conditions, while a Kevlar-loaded paper cone is mated to a treated cloth accordion surround for increased sensitivity without sacrificing durability.
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 98 dB sensitivity of this driver allows it to be used for professional audio, live sound two-way and three-way speakers; great for DJs too! Factory buyout, limited quantities! Compares to speakers at twice the price!
Note: For best bass response, install this 15" woofer into a 6.25 cubic foot cabinet tuned to 46 Hz with two 4" diameter ports that are 1" long.
