Celestion TF0818 8" Professional Speaker 150W
The versatile and efficient Celestion TF0818 8" driver offers excellent performance when used in bass and dedicated midrange applications. Its 1.75" copper voice coil is set onto a polyimide former, which assures good long term resistance to the detrimental effects of extreme high temperatures. A double half-roll cone surround, combined with an optimized Kevlar-loaded paper cone, ensure the speaker's frequency response is smooth and extended. The large 31 oz. ceramic ferrite magnet provides plenty of motor strength.
