    1. I would not recommend running the speaker wire with the electrical wire - if possible, have the speaker wire cross the electrical wire at a 90° angle.
    2. I've used Carol Speaker Wire - 12gauge in-wall rated from Parts-express.com You can get 100ft for $40.
    3. Tough placement for your surrounds...have you considered using in-ceiling speakers for the 2 surrounds?
    5. Not sure how much light is in the room...but if you can control it I'd recommend a projector. You can get an entry level 720p for about $600 and entry level 1080's for around $1100. Add a screen for a few hundred & you're on your way.
    6. It's very difficult to sound proof a room...you certainly want some sound treatment. The best tip I received for my basement was to install exterior/insulated doors for all inside doors. The exterior doors do a great job of preventing sound from leaving the room. You'll still "feel" the bass throughout the house.

    Good luck!

    5 feet of distance between speaker and electical wires is more than enough.

    I've used in-ceiling for my old house as well as a family member's house. Both had very difficult spots for normal rear speakers. After calibration both systems sounded very good.

    Crutchfield is nice for research but there are numerous projector sites that will sell for less. I'm partial to Panasonic. My older AE-900U still gives me an amazing picture. I had an acquaintance stop by yesterday for a demo. His TV room has a 50" plasma. He was very surprised at the quality of my projector on a DIY 103" screen. Even more when I told him the cost of the screen was only $75.

    I'll second the soundproofing comment. I did a little during construction of my house but I would have had to invest 10's of thousands to contain my bass. My dual 15's will excite the entire foundation of my house when I really crank it. It's a good thing it's just me and the wife and we watch movies together.

    Here's a good place to start: http://www.projectorcentral.com/home.cfm


    Buy the projector 1st...then buy a screen to match the projector.


    Also, ideally your front and center speakers will be placed at ear level. Your surrounds are good at 6' high.

    My Panny is a 3 panel LED. I watch HD movies, sports and TV series via DirecTV and OTA.

    I picked the Panasonic because of the adjustability of the lens. That feature allowed a wide range of flexibility in choosing where I install the projector.

    Follow Gary's link to Projector Central and view the current Panasonic model. I think it is the 3000x or something. Mine is almost 4 years old now.

    Are you asking about construction methods? I've seen everything from a regular platform built with the same techniques as you would a floor to cinder blocks holding up the couch. Pick the method that fits your room. I haven't built my platform yet but I'm going with floor joists 16" on center with plywood covering the top. Then I need to get carpet to match the existing carpet. I'll probably build it in the garage and roll it in on furniture dollies.

    My 2 cents worth on your questions... No. Keep the speaker wires and electric wires apart from each other. All wires (speaker, coax, electric, telephone, light control, so on) should either run parallel (with sufficient distance apart) or at a 90 degree angle to each other. Also, it is advisable to put all of your theater equipment on the same phase. The easiest way to do this is set aside one circuit to run all equipment and nothing else. I have a single 20amp circuit that runs my home theater and whole house audio. Your speaker wire should be UL rated for in-wall installation. Local building codes may dictate the specific rating required in your area, look for a rating of CL2 (typical home use) or CL3 (typical commercial use). I have Sheer Wire Oxygen-Free 14AWG speaker cable (part number 142OFC105) for all theater speakers except the subwoofer. I have quad-insulated RG6 coax cable for the amplified subwoofer. The coax cable is finished with a standard “F” connection then has an F-to-RCA converter on each end. In-ceiling speakers placed behind the last couch should work well. Surround sounds are meant to be less directional, meaning the listener should not be able to determine the exact location of the sound. I suggest building your raised platform from 2x10’s with 3/4” plywood on top. Glue and screw everything to minimize noise. Make sure the back of the platform has a raised edge or somehow prevents the couch from falling off. Add a pathway light on the step. Carpet/finish the platform to match the rest of the room. I created a calculator that can be used to determine the THX and SMPTE suggested screen size. It’s just an estimate, so don’t get hung up on the precision of seating placement. A few inches closer or further away will not matter. IMO, a front projector has the highest wow factor and makes your theater a little more future proof. To sound proof my theater, I used a sound insulation (similar to regular insulation, but with higher sound absorption factor) between the joists and studs. On the ceiling I added a layer of sound board and then a layer of 5/8" type X drywall. On the walls I put two layers of 5/8" type X drywall on both sides. I used sound insulated doors to the room and to the basement area (where the theater is located). My soundproofing focus was keeping outside sounds from entering the theater, and was less concerned about containing sound in the theater.

    Why the bannana plugs? Unless you are going repeatedly connect and disconnect your wires, you don't need them. Have you checked Monoprice for your HDMI cable and wall connectors? I like PE for speaker parts but you can find other accessories cheaper from other sites.

    If the suround speakers are ceiling mounted, I suggest just using a plastic telephone wall plate and just running the wire out to the speaker. This type of plate is available at most hardware stores for a buck or two.

    Take a look at www.bluejeanscable.com for the HDMI cable.

    Two wires close together will interact with each other. That's just high school science. Keeping your speaker wires bundled together for the sake of easy installation is more worth the time savings than the miniscule chance of interference. If you look behind my equipment rack, I have all kinds of wires laying on top of each other without any issues at all.

    Robert is right, Insulated speaker wire shouldn't give you any trouble if run in bundles. But you don't want to run it parallel to power cable. At most you want any cable that's carry a signal (data or sound) to cross a power cord at a 90 degree angle. Keeping them completely apart is even better. But running them next to one another is just asking for trouble. The voltage carried by power cable creates a much more powerful electromagnetic field and it will interfere with your signal cable, by induction most likely. (Stay away from light fixtures for the same reason.) Ask anyone who does network cabling for a living, they'll tell you.

    Regards,

    Joe.
