How can I configure two subs for my room? I didn't see another sub output on my Yamaha RX V2600. But maybe I'm missing it?
NGL,
The RC-70s are great. First, I'm not a speaker expert or audiophile so you'll have to take anything I say below in that light. (Obviously, I listened to these in 2 channel mode on Yamaha's Pure Direct) Second, I refused to buy anything for my theater that I didn't see/hear perform prior to purchase.
I auditioned Polk, Klipsh, PSB, & Infinity. I also listened to some Triad speakers but they were never really in the running because they were out of my price range.
The RC-70s have surprising range. In particular, I was surprised at how well it delivered low end bass. This was a huge short coming of the Infinity speakers. I'm not a fan of Klipsh's "bright speaker" technology and I'm confident that I'd have a pretty big headache after listening to these for 1.5 hours (sorry, klipsh fans).
I've never liked Polk speakers. I'm sure they make a great speaker but to me they sound muddy and unclear. This held true to form and the Polk's just didn't have the clearity and imaging you'd expect from a speaker priced at $900 each, IMO. (again, sorry Polk fans)
This left Energy and PSB. This was a really close call. The PSB's at nearly the same price level only had 2 drivers vs. the RC-70s w/3 drivers.
I find the Energys have great imaging, EXCELLENT clearity, and a broad soundfield. You can distinctly tell each instument apart. If great reprodution of sound & music is important to you, then I think you'll enjoy the RC-70s. You can probably get a speaker that delivers a little better in mid-range but I think you'd probably give up something on the low-end. I spent $750 (they were priced at $1000 each) for each RC-70 and would definitely do it again; if you get them cheaper, I think it's a no-brainer.
About movies:
When I watch movies, I can almost never tell that the sound is coming from 2feet below (or to the side). In fact the sound and imaging is so good, it is truely intuitive and you get completed wrapped up in the movie.
Hope this helps!
