Product Details
Peerless GBS-250F38CP01-04 10″ Paper Cone Woofer 4 Ohm

The Peerless GBS-250F38CP01-04 10″ 4 ohm subwoofer provides a very slim profile that is capable of large excursion. A unique treater paper dome helps to provide room to move the motor assembly and spider further forward without sacrificing excursion or efficiency, which is an issue with many low profile driver designs. A highly optimized ferrite motor and unique suspension layout combine to give a cost effective solution in a previously unavailable package.
