My condo layout is funny because there is a 2-foot wide post smack in the middle of the living room (there is a pipe that runs through the building in it). To make use of it, I decided to wall mount a 65" TV onto the post (center of TV 43" above the floor, roughly eye level for a short guy like me sitting on the couch) and build a low (50 cm) console around the post.
I can put the center speaker (a) on the post above the TV or (b) below the TV, to one side of the post (with the subwoofer on the other side).
If I choose (b), the speaker will be one foot off center and just about 10cm from the floor.
Is this a good idea?
If I choose (a), the speaker may have to be a bit higher up (not directly above the TV) and I'd have to try to angle it downwards when it is mounted. I am planning to have five B&W 685s around the TV, so mounting the center 685 means having to build a metal bracket to hold it and bolt that onto the post (or the ceiling).
