My understanding of the Uni-Q driver is that they do not want to be aimed at you. They have a pretty good wider dispersion pattern as I understand it. Generally, ear height is best, but this isn't a critical listening setup, I'm guessing. For a bedroom setup, I'd still try to get some balance between the two speakers... depending on your room, dunno how difficult that will be.
I asked about the BMRs because I know those have some unique characteristics: you want the Tweeters at ear height. Dennis also designs his speakers to not be toed in, though I have done so with good success... but this depends on your distance from them. He has suggested being 15º off access IIRC, with no toe-in. This creates a pretty long isosceles triangle though. Regardless, for these, ear height is a must, and absolutely level between L/R.
