How close are you sitting to the 3.7s?
Just my opinion, but using a front row center seat as a reference is faulty. It's as if you're trying to bring the audiophile experience to the concert hall. Sit further back, even if only a few rows, and get better enveloped in the blend of direct and hall sound.
Unless you can optimize, or at least get real close, you would be better off with two separate systems in different rooms. In a normal sized room with any pretense of domesticity it will be hard to properly place two different sets of speakers. You could always move the speakers in and out of their optimal spots, but I think you'll get tired of that routine fairly quick.
