Product Details

7-1/2" Paper Cone Woofer 8 Ohm

This 7" paper woofer with foam surround was designed for use in home theater speakers, and is great for use in small sealed enclosures as bookshelf, center channel, and satellite speakers. An oversized, 7-1/2" trim ring allows this woofer to be used in cabinets with a larger than normal cutout. A three-layer 1" voice coil on an aluminum former increases power handling to a respectable 50 watts RMS.

Alternatively, you can repurpose this woofer as a midrange/midbass speaker in larger 3-way cabinets or even as a car audio speaker. Save over 40% off the original retail price through this Parts Express exclusive buyout. Quantities are extremely limited, act fast!
