I finally got it all hooked up and have had some time to mess around with a few configurations. My current setup is as follows:
Fxi5, CSi5, RTi12 (top) powered by onkyo 901
RTi12 (bottom) powered by behringer ep2500
I have the reciever taking the signal via 6 analog rca inputs from a b-enspirer sound card in my computer. The reason behind this is the spdif interfaces on the onkyo only support 96/24, while the sound card is capable of outputting 192/24 down the analog (I realize there are few sources that are encoded at such a rate, but I like big numbers). I tried it both ways and the analog sounds better than the digital. Also my reciever has an odd ticking-static-beep noise when it is decoding a dts/dd signal.
After a few "crank it up real loud" sessions, I finally settled in on a decent movie... War of the Worlds. Morgan Freeman's intro dialog was RAZOR sharp. I was almost certain he was hiding under my table. Once he started talking I stopped tweaking the volume and just sat there. It was set at ~-4dB on my reciever. The volume level seemed to be normal, even at such a high setting. After about 12 minutes into the movie I rediscovered the concept of dynamic range. The RTi12s created an extremely visceral and amazingly accurate representation of the lightning. The growth of power between the first and last lightning bolt was astonishing. It was almost as if my house was being assaulted by the storm.
So at this point I was thinking "wow that was totally worth the investment." I didnt realize there was more to be had... The scene where they get in the van and start driving off came up and completely demolished my highest expectations. When the tripod started to blow away the bridge, my brain was saying "please turn it down", but I just couldnt move. For the next minute I couldnt move. I just looked around wondering if I had heard everything correctly. I played it again to make sure, and there it was, exactly as I thought I heard it.
I fear im probably going to start rambling incoherently, so I will stop here. Needless to say, if you can afford these speakers, a decent amp, and enjoy movies, there is NO excuse for not buying them. Also to anyone who says they arent "good for music", please tell me what kind of music you are listening to, because the Eagles HFO Dts was amazing. :D
BTW, I plan on constructing a sonotube-based subwoofer in the near future to round out the experience. Anyone who has any thoughts about these projects, please feel free to contact me with suggestions.
