i have an L shaped room over a garage. The vertical part of the L is about 15 x 20. I have a TV, with VHS, UMD, DVD, Blu-ray, receiver, vinyl, cassette, 8 tracks, etc. playing into a pair or CS G911. This is late 80s, early 90s consumer rack system level stuff. Behind the seating is the horizontal part of the L that is about 10 x 20 with bar, table, bookshelves, etc. Is there an optimal way to orient the speakers? Thanks for any tips.
