Our take on the Polk Audio 12-Inch Powered Subwoofer
The Polk Audio 12-Inch Powered Subwoofer is a ported home-theater sub built around a 12-inch long-throw driver and a Class D amplifier. It is aimed at movie and music listeners who want real low-end weight without a big floorstanding speaker. Against smaller 8- and 10-inch subs it moves more air and digs deeper, but it is a large box and a single sub can sound uneven in big rooms. Owners generally rate it as solid value for a first serious subwoofer.
- 12-inch driver gives more output and depth than 8- or 10-inch subs
- Ported cabinet tuned for movie soundtracks
- Class D amp keeps it reasonably efficient
- Line-level and speaker-level inputs for flexible hookup
- Common choice for a first dedicated subwoofer

Questions and answers
- Is a 12-inch subwoofer too much for a small room?
- It can overwhelm a small room if the level is set high. Careful placement and a lower gain setting usually tame it.
- Does it work with a stereo receiver?
- Yes, it offers speaker-level inputs for receivers without a subwoofer output. A line-level sub out is the simpler hookup when available.
- Should I buy one or two?
- Two subs even out bass across a room, but one is a reasonable start. Add a second later if you hear uneven bass.
- Where should I place it?
- A corner boosts output but can add boom. Try a few spots along the front wall and pick the one with the smoothest bass.
- Is it good for music as well as movies?
- It handles music well for its class, though it leans toward movie impact. Music-focused buyers may prefer a sealed sub.
