I've followed this thread with some interest Steve. You might remember that I shared your enthusiasm for Q-Acoustics speakers in earlier threads on AoS . I also had a pair of 2020i and was equally impressed by their performance. I was for a while toying with the idea of moving up to the 3050s, based on your positive experience, but in the end opted for a pair of Quad 22L floor standers instead (mainly because they were going very cheap locally = £200...)
I'm curious about your current set-up. I have a 'room with a bay' very similar to yours and initially had the floor standers in pretty much the same place as where you have yours. However, I suspected that they were not giving their most in that position .. a slight lack of definition overall and wooliness to the bass that I figured was down to deflected waves bouncing around the 'dish' curve of the bay window. I have since moved them to a side wall (see sketch below) and found that this to be a marked improvement - much better definition and more bass punch.
Just wondered if you had experienced anything similar or had tried them in any other part of the room?
