Two speakers and two subs are really the right way to do it, and I have no doubt that your two RCFs sound excellent. I almost bought the RCF Evox myself, but I just don't like to carry and set up two systems. The most that I am willing to do is a 2.1 system like the Nano 608i, dB tech ES 503, or Yorkville exm 400. The Nano 608i is a much improvement over the Nano 300. It sounds big and warm. I am hoping for RCF to release a 2.1 stereo system. If I were to carry two speakers, I'd be really interested in the RCF TT08a. RCF just released its second version. An 8 inch powered speaker. It will be over $2,000 for each speaker.
