Overview
The JBL JBLS660PDKWSAM is a powered subwoofer with a 12 inch driver rated at 500 watts, connecting via RCA. Finished in dark wood for tabletop placement, it measures 16.53 x 16.53 x 16.53 in and weighs 25 lb.
A subwoofer handles the low frequencies that satellite or tower speakers in a surround system generally can't reproduce on their own, so this is a companion piece rather than a standalone speaker. The cube-shaped, 16.53 inch cabinet is sized to sit under or beside furniture, and the dark wood finish is meant to blend into a room rather than stand out.

Who it's for
Suited to home theater builders who need dedicated bass to pair with existing satellite or tower speakers. Not a fit for anyone looking for a full-range standalone speaker.
