Overview

Celestion FTR08-2011D 8" 200 Watt Professional Woofer 8 Ohm

The versatile Celestion FTR08-2011D 8" woofer offers excellent performance when used in bass and dedicated midrange applications. Its 2" copper voice coil is set onto a polyimide former, which assures good long-term resistance to the detrimental effects of extreme high temperatures.

An M-roll cone surround, for controlled excursion, is combined with an optimized Kevlar-loaded paper cone. This ensures the speaker's frequency response is smooth and extended. The octagonal frame allows for closer woofer-to-woofer spacing, reducing comb-filtering effects in the mid to high frequency response.
