Product Details

5-1/4" Woofer Blue Surround Shielded 12 Ohm

This 11 ohm, 5-1/4" shielded woofer with blue surround was designed for use in home theater speakers, and is great for use in sealed, compact enclosures as bookshelf, center channel, and satellite speakers. The shielded motor also makes this woofer a great candidate for computer speakers that are placed closely to sensitive electronics. The unique 11 ohm impedance allows you to wire a pair in parallel for MTM use with a safe 5.5 ohm load.

Alternatively, you can repurpose this woofer as a midrange/midbass speaker in larger 3-way cabinets. Save over 60% off the original retail price through this Parts Express exclusive buyout. Quantities are extremely limited, act fast!
