running wire in walls/floor

Any good custom installer can do this for you. Ask some good shops in your new town (or better yet a friend in the new town) who they'd recommend. You should expect someone to come out and look at the house and give you a professional quality estimate on the work prior to beginning. Make sure you address how the wires will be terminated, if at all, and make sure the installer understands what you want. Don't pick the low bidder, pick the best bidder. Good luck.

Make sure they are licensed (if they have to be in your location, some areas low voltage installers don't need licenses like electricians), bonded, and insured.

I always wondered why when constructing a house or a sound room ABS piping can't be run in walls or between floor joists as a conduit for speaker cable, that way if you do think that speaker cables improve music reproduction and that upgrades can be had to make a difference you could simply tie the end of the new one to whatever was passed through and snake the new stuff in there. Am also wondering if the ABS would not add an extra level of insulation or at least RFI isolation to the cable. Just a thought.

I love your idea , Pbb

ABS can work. also, there is a flexible conduit that is a blue/green color that is often added to new construction and add-ons. this way someone can pull whatever he wants as times change. someday we will be pulling fibre optics for phone service through our houses.

Jdodmead, there are plendy of decent installers who can do what you want. Check out custom telephone/cable T.V. installers in your area.

We are currectly remodeling a house, and I have done what Pbb mentioned. My first thought was to use PVC pipe, but my electrician informed me of a product mfg'd by Carlon - it's a blue flexible corrugated plastic pipe in sizes from 1/2" up to 1 1/4 inch. Locally they call it "Smurf" because of it's color. Lowe's sells it in 10 ft. joints, or you can buy off the spool at your local Electrical supply house. The family room is new construction, so it was relatively easy to install by running under the floor in the crawl space. I had 3 runs for the rear spkrs and sub. The ends terminate at the opening of a "frame", which is plastic and provides a border for the drywall to be cut around. They use these now for running phone and multimedia wiring. I intend to cover the frames with switch plates, which will provide the opening for the cable to pass through. Makes for a very neat installation. Existing construction may pose a few more problems - you will have to have access from either a crawl, basement or attic, and if you're dealing w/ exterior walls, the insulation may make it difficult to feed in the tubing. Would make a good weekend project for the DIY'er, or check with your electrician.
