10″ subwoofer with patented filter circuit and excursion limiter.

The SW4 delivers the same great sound you’ve come to expect from the SW series, but it takes up less than a cubic foot. Don’t let it’s small size fool you, though – it extends flat to 25hz. the SW3’s ideal for hi-fi bass in family rooms, bedrooms, offices, or as a supplement to a micro home theater system. Its small size also makes it easy to run multiples around the room for improved bass distribution.
