Klipsch would be an obvious choice if not for the horn.
I'm a Klipschaholic so my opinion is biased -- but I think you could do a lot worse than Klipsch for a rock-friendly setup. I find that McIntosh and Marantz both have a very warm sound which helps cut the horn brightness. My main system is a pair of Klipsch Forte Is with Crites crossovers and titanium tweeter and midrange diaphragms powered by a McIntosh MA6200 and I find it most satisfactory for my musical tastes: I was also quite impressed with a Marantz 2220 I keep around as a spare. (I should also note that my tastes in rock are more 70s Prog and blues rock -- think King Crimson and Robin Trower -- than arena rock and *ugh* hair metal).
My Forte Is (which were cosmetically battered but sonically fine when I purchased them) cost $300 and I spent another $500 in updates. A new set of Forte IIIs, which have just been released, will set you back $3600-4400 depending on the finish. You might also be interested in the Forte's big brother, the Chorus: they typically go for $950-1250 on the market. I've seen used Cornwalls going for $850+ ($4400/pr new) and LaScalas anywhere from $1k up ($8k a pair new). And if you have the corners and the room for two refrigerator-sized speakers, used Klipschorns can be had for anywhere from $1500 to $5500 a pair -- a new set will run you $11k or so.
