I have the Denon 3805 with Polk RTI 12's and RTI 6's in the rear. I think I could have done better for the money than the 12's. The 6's though, are excellent rear channel speakers if you have stands...if not, get the 8's as they will cost the same as buying the 6's and stands. I tried the 8's, 10's and 12's all in my house at one time. The 10's were my least favorite. There seemed to be a hole in the middle of the soundstage. The 8's with a sub aren't much worse than the 12's, but the 12's were still better. $800 better I don't know. I would get the LSi 15's if I had a chance to do it all over again. Don't let people tell you Polk is crap. This site doesn't speak of them because they don't get kickbacks and Polks are sold in big box stores so people assume they are crap. Polks were known as some of the best not long ago before they went mass market and now high end stores won't sell them because they can not compete. The day I saw Polks categorized with Bose on a review here was the day i learned to read all reviews subjectively. Bose is shiite. Polks are not.
All you have to do is look at the fact speakers like Axiom are constantly reviewed and pushed through advertising on this site, and there is NEVER mention of Polks. Polk RTI 12's are better than any Axiom product. Hands down. Axiom pays the bills here, and companies like RFH...their banners are everywhere on this site because, they pay the bills. Sorry Clint but it's the truth. and I am not looking to tick anyone, especially Clint off as I LOVE this site.
Any ways...
I never tried it, but if I were you, i would try the RTI8's all around with a good sub...that would be killer for DVD audio or 5 channel stereo.
