Building my first and hopefully last new house, I will be placing TV/Surround setup in the living room. Room has vaulted ceiling in a 25 x 16 open plan combo DR - kitchen - LR. A 5' high wall divides what I see being the back or seating 1/2 of the two areas. Photo is from smaller house - ignore dimensions shown - FP is the same layout. I plan on placing TV-stereo on MB wall, side surrounds by front door and end of divider wall, rear surrounds opposite of TV. General layout. Speakers - Green Tv - Blue Stereo - Yellow Furniture - Red Possible conduit - Orange Concrete slab foundation - With cathedral ceiling. Should I have pvc or "conduit" placed in the slab to accommodate wiring under the "slab" floor starting behind stereo in the wall at a double gang box, going to these locations so I can pull speaker wire continuing up in the walls to single gang receptacles at these locations as required ? Surround by front door can be run in wall. A straight run under the floor would be a lot shorter than going up and over and then down from a cathedral ceiling though! Never been through construction and I'm not at all familiar with slab foundation construction I know once it's in it's going to be hard - eh ? impossible to change it ! Almost forgot ! Recommendations for in wall speaker wire - I've been checking httP://WWW.AudioAdvisor.Com and possibly http://www.CobaltCable.com In-wall wire. Sounds a bit pricey for me - but it's a long term investment. IMHO Cobalt makes good - reasonably priced - well built IC's and speaker cables, I like mine.
