Outstanding in-floor sub
Crutchfield Customer Review (What's this?)
I'm a big Polk fan. In fact most of my upcoming house build will feature Polk products (in-wall, in-ceiling speakers, and in-floor and in-wall subs). I am installing 4 for these in-floor subs in my great room powered by 2 Polk SWA500's (designed to match up w/these subs). While I haven't installed these subs yet (house is still under construction), I have listened to them simply outside of the shipping box and they perform great (in my current home). I have demoed them on both music and movies and there output is very nice. Stats say they play down to around 30hz and to my untrained ear that seems accurate. If you need an in-wall or in-floor sub that plays lower I would suggest looking at other alternatives. Most movies and music will sound great on them though. I have another manufacturer that I will be using for my dedicated home theater room (6 15's!!!). The fact that you can hide the sub under the flooring and all you see is a small grille, these subs are hard to beat.
Pros: performance, out of sight sub
Cons: under 30 hz material, pricey when you consider the cost of the sub and amp compared to a "normal" sub, but then again it would take up floor space.
