This thread just popped up in Trending.... I hadn't seen it before. Well, I know which way I'd head, if I got permission of course! A garage gives just enough room to squeeze two rows in, and fit an AT screen too! (One of the best things you can do for a dedicated room IMO). My own room is 5.5m long, albeit a little wider than a single garage, at 4.4m. I've lost about 30cm in each direction due to my false walls hiding the speakers and acoustic treatments, but you don't have to do this if you keep your speakers visible on-wall, and acoustic treatments can be a handful of insulation filled frames mounted strategically around the room. I see the entrance door would be midway, or nearer the front, which means you might even be able to squeeze a 3 seater couch along the back wall, with a two seater up front. I would advise against recliners in the rear row though, they take up a lot of room, and are very rarely reclined, as your eye to screen angles are more comfortable sitting upright when you're elevated on a riser. (I know I have recliners, as I wanted that uniform 'cinema' look, but I may actually get rid of them in the future for a fixed sofa - but having spent so much on them am loath to do so right now)! If you were to go for your plan two posts above this one, I'd forgo the rear surround speakers, and just aim for 5.1.4 - the rear speakers would be too easily localised by people sitting on the couch, and would pull you out of the movie, rather than contributing to it. IMO. Not so important with a two row setup, when I'd go for the full monty, as the MLP would be on the front row, and the rear seats would naturally be the compromised ones, sound-wise (but most guests wouldn't really notice). Again, IMO. The other thing I'd look at, if going for the 'living room' setup, would be an Epson ultra-short throw projector, the LS100 - it's only 1080p, but will give a mahoosive image, even with the limited space available. You could either hide in-walls behind a very thin AT screen, or project straight onto the wall, with speakers arranged a la TV setup. Best of luck! And don't forget, we here at AVF, are always happy to spend other peoples money!
