    lol I was thinking the same thing. I don't even want to know how much his cabling cost and the funny/sad part is you can get vastly superior cables for less $$$.

  2. Not 13.1 but 5.1 by Zacha · · Score: 5, Informative

    I don't think the 13.1 in this story is 13.1. I think it reflects the theatres' 13.1 speaker implementation of 5.1 channel sound.

    SPEAKERS:
    3 across the front
    4 down each side
    2 at the back

    CHANNELS:
    #s 1-5 played back over speakers like this:

    ...1...2...3...
    4.............5
    4.............5
    4.............5
    4.............5
    ....4.....5....

    The only difference between PVC and plenum-rated cable is with regard to electrical/fire code compliance. Use whatever is cheapest and meets code. The advantage of plenum-rated cable when making runs through vent ducts is when your house catches fire, the burning cable jacket won't flood your house with toxic fumes by way of your HVAC system.
