Polk PSWI8M (Black)
8" 70W wireless powered subwoofer
When you add a subwoofer to your home theater system, you're not just adding deep, sound-defining bass. You're also adding long wires. Unless it's the Polk PSWi8M subwoofer. This 8" 70W powered subwoofer features a 2.4GHz wireless transmitter with Polk's Digital Logic, so that it not only eliminates long cable runs, but also optimizes your bass signal for movies and music as it sends it.
