5.2 now, 7.2 later
So, I have a new HT in progress of being built. I had pretty much decided placement, but as I was working on getting all the wiring in, I began to have serious reservations about side speaker placement, and thought I would reach out to the folks here that are much smarter than I.
Initially, this is a 5.2 setup as marked out largely in red X's in the attached diagram. That wiring is mostly in at this point. It has the down side of the rears not really being behind as such - they will be hung a bit high, but will be essentially overhead of the rear row of seats (2 rows total in a 4 front, 5 back configuration). The fronts are floor speakers. The two subs will be front left and rear right (essentially just to the right of the last row).
Initally, I was planning on putting the prewire for the sides into the front of the rear riser - just behind the ears of the front row, and a bit further and in front of the back row. I am now, however, thinking that's too close to the rears, and am looking for some input. The configuration looks like the attached file. I was initially going to place at the spot marked in blue as "A" (even with the rear of the first riser, and front edge of the 2nd and rear riser), but am now thinking that moving further away from the rears to B or even C makes more sense, and I'd like input from the much better educated crew here.
The green X's are fronts, center and rears. The red X's are subs. The room is roughly 15'x19', with the risers being 6' deep each.
Thoughts on where the side pre-wire should go? It will likely be 6 months to a year before I actually add sides, but want to make the right prewire now before the finish work is done in the room.
