If you come up through OKC anytime soon then you can have a listen to mine. I've heard the Infinity Primus 363's, Klipsch RF-62/82, Polk RTi bookshelves and a few other speakers here and there....these are definitely a crazy buy for their price. I felt the Klipsch was okay, but had a recessed midrange and the top end was too much. The Primus was decent, especially for it's sale price at Fry's. Not a bad speaker, but could come off a little hot in the upper midrange/lower treble too me. The RTi I heard was just way too forward for my liking. This particular audition was in a store though, so I can't put much into judging that.
I was VERY leery about ordering the EMP stuff as something that looks that nice, with that many drivers can't sound that great (...axiom's large center and m80 complaints come to mind), but I was blown away at their imaging and depth. Cast baskets, etc etc are great to have, but not a requirement to get great sound. I've wondered if they're able to sell them this cheap since TO ME, it looks like they're using the same cabinet as the RBH towers. I'm sure the RBH towers get more beefed up in the end and I'm positive the front baffles are different as EMP has told me, but the dimensions and everything else are the exact same. The top end needs a slight bump on the tweeter, but if you use any EQ it'll fix that. Nothing jumps out at you as they're a very neutral speaker. I'll second that they disappear in my room, even sitting 3-4 feet from the sweet spot. I can sit in front of the FL speaker and it's still glue'd to the middle (running phantom center at the moment until TV goes on the wall). You'll definitely want a sub, but most speakers under...well...a good chunk of money will need something to carry the weight of the lower end.
Oh, the 1713 should be plenty for ya. I'm driving mine with the 1712 & my room is 22'x20'-ish (w/ 11-12' ceilings)...very open too. It has more than enough to get insanely loud. The dynamics of the e55's are mind blowing. I can't hear them break up until I'm reaching near reference levels on the AVR, but that was a one time test & it was very slight breakup. Anything that loud is just too loud for long lol
