Watch out for the Klipsch KP series too, they were the professional line, but generally referred to as Pro versions of the home ones. 201's were Heresies, 301's were Cornwalls. My 94 ( I'm pretty sure) KP-301's put every other speaker I've ever heard to shame, by a good margin. There is no mistaking the sound. I will never get over how natural horns and guitars sound from these horns, there's something different that it seems (to me) that conventional tweeters can't do, the Klipschs seem to disappear, and all the other ones make themselves known. Sometimes I could care less, like at work, I just want to have good sound, but when I get to sit in the sweet spot, I want my Klipschs. Good buy IMO for $450, and no gas to boot! Enjoy, I hope the cabs turn out nice. Crexrun
