okay need some expert views here. I am lucky to have a large basement (den for those USA friends). I have a few options but none seem ideal. Picture 1. Current set up (ignore little speakers these are going to be KEF Q150’s. I have potential TV reflection and an open space on the right . Cannot move TV without major rewiring. Picture 2. Narrow end of rectangular room. Concerned about blocking from large chimney. Is this likely to be a problem ? Better enclosed space for sure. Option 3, move large sideboard and have speakers again on short rectangle space? Thoughts?
