There's been some excellent advice already in this thread. I'd particularly highlight the contributions by JbsJbsl and Bob Bundus. I'd add/stress/reiterate the following:
The Khorns will go low only when properly placed in two adjacent corners as they were designed. Either that, or you must build false corners on them (not pretty IMO). Even then they're only going to give you an honest 40hz and there are plenty of speakers that will do better on their own in terms of bass. None of them will likely sound like a Khorn, as has been pointed out. Their sound is unique, and more often results in a love-em' or hate-em' response. As Bob points out they are extremely revealing of everything upstream and they'll take no prisinors there. A LaScala or Belle will have a similar character to them, but will not require the corners, but in turn will not go quite as low. If you are a bass-hound and want something that hits you in the chest, I would include a subwoofer in my budget for any one of these considerations. Matching the best upstream components is absolutely critical with these speakers and can make or break your investment. Also, none of the larger Klipsch Heritage line conform to your size requirements that you listed. In comparison they are quite large, the Khorns being the largest of the bunch and a formidable speaker indeed.
Two speakers I've heard in the past that do what it seems like you are asking, while both remaining relatively reasonable in price, are NHT 3.3's and the more current Gallo Reference 3's. Both require significant current to do their thing though.
Per the suggestions above, if you're stuck on Klipsch for some reason, go out and try to listen to a few set up well. Bring your own music to listen to.
Good luck!
