Celestion FTR08 2011D 8 Inch 200 Watt Professional Woofer Driver 8 Ohm
Celestion FTR08-2011D 8" 200 Watt Professional Woofer Driver 8 Ohm
The versatile Celestion FTR08-2011D 8" driver 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 driver-to-driver spacing, reducing comb-filtering effects in the mid to high frequency range.
