Sharper Image SA251 Passive Subwoofer

The Sharper Image SA251 is a compact, wired passive (and sometimes labeled active/powered depending on the listing) subwoofer that delivers 20W of RMS power and 40W of peak power.

Featuring a 5.25-inch woofer, its down-firing bass reflex design is ideal for augmenting small home theater setups.
