It is the Polk Audio - 10" 200W Powered Subwoofer - Black.
I did check and this sub-woofer is supposed too have it's own amp. Actually I think it is 100w continuous and 200w Peak.
I will say that obviously it is Polk Audios lower end subwoofer. I was a dissapointed because the 3 speaker large Polk center channel speaker I bought is great. The center Polk speaker was fairly expensive, and the 4 Bose speakers are not bad. They are the large lower end 115w Bose bookshelf speakers that I wall mounted. For only $130 each Bose speaker they all sound pretty good.
Perhaps I need to add a seperate equalizer to the receiver. Then again it may be a sub-woofer problem, because lets face it... This subwoofer being new almost seemed to low cost to even be true.
I did see a nice Yamaha powered sub with the same specs, but it cost double what this Polk sub cost new. Perhaps that higher cost Yamaha sub will match better with my receiver.
Who knows, perhaps I will just return this Polk sub and not even bother with a sub for now. I'm getting good mids and highs with a little bass right now. I listen to classic rock so I suppose I don't need a seperate subwoofer. Not to mention I am peaking out fine now on all the 5 current speakers, which is already WAY overkill given I live in apartment. 2 neighbors have already reported me for the noise level and that's not even half way turned up.
I figure I'm cool with their big dogs barking all the time, so I would get a nice Sub and ignore their complaints.
