My parents are looking to upgrade their Klipsch RP3 Towers to something better. I've looked at brand name speakers around the $500 range and haven't found much that may be considerably better than the RP3's and worth the upgrade. Maybe a pair of the Polk Lsi7 or the bookshelf rockets The reasons for upgrading are that the Klipsch's lack openess in the high end part. When playing the Eagle's Hell Freezes Over or some Eric Clapton, the instruments aren't so clear and enjoyable. However the vocals were good and strong but a little raspy. (Klipsch fans don't hate me). Here's their setup http://www.pbase.com/image/14648858 http://www.pbase.com/image/14648853 I let them hear my NEAR 10m II bookshelves which have great balance, imaging, and terrific highs, but just little laid back in the vocal range. They loved the clarity but said it lacked a bit more punch in the vocals. So I need to know which kits have great mids and highs for a 15x15 room and possibly 20x20. I also need a kit that doesn't have too much placement issues because how the setup looks now will remain. I'm willing to look at Towers (my parents preference) as well as bookshelves. The low end will be taken care by the SVS. This is for music and HT 50/50. Most importantly the budget is $500 assembled (unfinished is fine as I can do that). I'd like to get a matching center down the road for around $200. So budget is about $700. I've heard lots of great things about the Av-1+...any others? Also I hope that the kits you guys recommend offer free (or at a low charge) x-over assembly...the cabinets...I think I can have someone make a pair of mdf mtm's for around $130.
