Overview
The Klipsch R-12SW is a 400 watt powered subwoofer with a 12 inch driver, built as a floor standing wired unit finished in brushed black vinyl.
A 12 inch driver at 400 watts in a cabinet sized 21.5 x 21.5 x 18 inches is built to move real air across a living room, not to disappear under a desk. Wired means it needs a cable run back to a receiver rather than a wireless link.
- 12 inch driver
- 400 watt power rating
- Floor standing wired design
- Brushed black vinyl finish
Who it's for
Suited to a home theater or stereo setup that wants a dedicated floor standing bass unit. Not a fit for anyone needing a compact sub for a tight space.
Strengths and trade-offs
Drawn from this product's published specifications.

Performance notes
The combination of a 12 inch driver and 400 watts of power in a cabinet this size is aimed at filling a room-sized space with low end, not at sitting quietly in a small corner. The wired connection means planning a cable run to the receiver.
