Overview
This Polk Audio subwoofer pairs a 12-inch woofer with a 300-watt power rating in a floor-standing black cabinet. It connects via RCA, the standard subwoofer-output hookup on most AV receivers.
At 19 x 14.3 x 19 inches and 51 lb, it's built as a floor-standing unit rather than a compact under-desk sub, so it needs dedicated floor space. The 12-inch driver and 300-watt rating point to a unit meant for filling a living room or home theater with low end rather than a small apartment setup.
- 12-inch long-throw woofer
- 300-watt power rating
- RCA line-level input
- Floor-standing black cabinet
Who it's for
Home theater and dedicated listening room owners who want a floor-standing sub with real driver size and power behind it. Not for anyone tight on floor space or wanting a wireless connection, since it's RCA-wired only.
Pros and cons
- 300-watt power rating
- 12-inch driver for low-frequency output
- Simple RCA hookup to most AV receivers
- 51 lb, not easy to reposition
- RCA-only, no wireless connectivity listed
Performance notes
The 12-inch driver and 300-watt power rating are the two figures that drive low-frequency output and headroom here. RCA is a wired, line-level connection, so it depends on a receiver or preamp with a dedicated subwoofer output. At 51 lb in a floor-standing cabinet, it's meant to be placed once rather than moved often.
