Usher 8945A 7" Carbon Fiber/Paper Woofer
The 8945A woofer is one of Usher's most popular drivers, featuring their low distortion motor system and a carbon fiber/paper blend cone. High excursion capabilities combined with the rigid yet well-damped cone provide powerful bass without a harsh midrange. This is one of the best all-around woofers for traditional 2-way bookshelf and compact floor-standing systems.
