I'm planning on getting some new speaker's for my HT and using them for main's. I currently have a CS245i center, old S4 bookshelfs for my main, f/x 300i for surrounds, and a PSW250. I plan on replacing my S4's w/ either LSi7's or RTi38's. Which one will more likely match my setup. I know the tweeter is different on the newer LSi's, but those LSi's just look soo damn sexy! Eventually, I will upgrade to 7.1, probably using my old S4's for rear surrounds. Any suggestions out there? Thanks.
