I don't remember the exact size of the room but I'll have it measured soon. I do know that distance from the far right brick wall (one with the fireplace) to the stairway up to the loft is 15 feet. The cielings are very high (obviously) but I don't have even an estimate on that.
Hard to tell from those images but that fireplace is dead centered on that wall. putting the tv either left or right of it would pretty much make it very ackward to watch from any position I suspect.
I have a pair of oldTechnics SBT200 tower speakers, a 5 set of Energy Micro RC satellite speakers (woman wouldnt let me buy anything that wasn't "cute". she demanded bose...ug... and i compromised with those) and a subwoofer that isnt worth much of anything (looking to replace).
My receiver is an Onkyo 616 receiver a samsung bd-d5700 blu-ray player and i have a verizon fios HD box.
I was thinking that since the cieling is very high that I would take a pair of the energy speakers and put them in the "front high" location with the Technics as the normal front but I have doubts on that working well due to voice matching. I used to just have those tower speakers in a different room on the B channel, just for music.
