Hi, I'm currently in the process of building my new home, and while it has a dedicated HT, I'd also like to take advantage of DVD-A and DTS Audio on my living room. I'll soon post pictures of my living room. It's trapezoidal in shape, with one of the walls made of stone and the rest of them made of bricks, with vaulted ceilings decorated with oven-heated bricks (the closest style I could say it is, is modern-mexican). Anyway, I was thinking about installing my MartinLogan system there, too, so I am currently thinking about hiding my 6.1 system either on the corners of the roof, or built into the walls. The speakers I'll use are Definitive Technology ProMonitor 80's all around. The subs will be a pair of Definitive Technology ProSub100's. I have a couple of questions, though... + Mexican construction techniques are very different to US' ones. So myy house has concrete pillars, brick walls all around and stone (earthquake proof, I hope). Any changes I make to the walls have to be made now in order to run the cables through conducts throughout the walls. + So I am wondering, if I wall-mount my DefTechs (using the included baffle, of course) will I hurt their sound quality much? I know there's a tonal change from mounting them flush with the walls, but I don't know exactly how much would it be. + Would I be better off by installing them in the corners of my roof and aiming them at the seating area? They wouldn't look that integrated, but if I can get away with some extra fidelity, I'm all for it. TIA Javier.
