I agree the room layout is not ideal for music listening, but I'll give a dissenting opinion in that UK_UV needs to run to a 5.1 setup rather than a 2.1 system. The center channel and the surround speakers widen the sweet spot to all the seating positions in the room, not just that one seat. I don't bother tweaking for imaging or spatial placement, it's a recording artifact you don't even experience in a live performance.

I would have no problem recommending the VP180OW or VP160mini OW paired with M2OW or M3OW, I'm one of the vocal minority who believes the center channel is more important than the left or right front channels. M5HPOW if you want to make sure it pumps enough SPL.
