Okay, I think I might have done something foolish. After weeks of research and price searching, I settled on the following setup: 2 Polk RTi28 bookshelf speakers for front L/R Polk CS245i as the center channel and 2 Polk R10 bookshelfs as rear L/R and the Pioneer VSX-D811s. Now I already have all the speakers and am now waiting for the receiver to arrive in the mail. So after getting the Polk RTi28 speakers I found out that they are have a nominal impedance of 4 ohms and I also found out that the Pioneer VSX-D811s has a problem with speakers less than 8 ohms. My question is: does anyone have this setup? or will this setup work ok? or am I kind of screwed and going to need a different receiver? and if I need a different receiver, can someone recommend a receiver that has comparable features in the same price range as the VSX-D811s ($300ish) Thanks for any help!
