I'm currently thinking about building a modest home theater that will share the space with my living room. Due to aesthetic concerns, I'm leaning towards a plasma screen mounted on the wall flanked by three in-wall speakers (left, right, center) and two in-ceiling surrounds. Likely going to put the rest of the gear on a rack in a closet, so I'll need to do some IR work too. I live in a bungalow that has attic space above and crawlspace below the living room, so I would think the install would be relatively easy. I spoke to a well-known local custom installer and was quoted $170/hr (2 men at $85/hr.) for the labor cost and approximately 2-3 days to do the install. That's around $4K for the install. Does that sound reasonable? Anyone installed their own in-walls and IR stuff and care to share their experience with how easy/hard it is to DIY?
