    In my new theater room I am building I am ending up with some long speaker cable runs for my fronts and passive subs.(Unavoidable in my room)

    I am afraid this might end up giving me problems. My acutal run is 60 feet. Is there anything I could do to avoid a problem or do you guys think 60 feet should be ok?

    Just use an appropriately sized ga. of wire, and you should be fine. With what speakers? You will be drawing a lot of current with dual passive subs (explain why that is unavoidable? your HT site is closed...) In which case you will probably need to go 10ga or better.

    John thanks for the quick reply;

    I am using XLO/VDO ER-11(12ga for LCR) and ER-12(9ga for 2 passive Subs). B&W speakers Bryston amps.

    My room is very long, and the only good spot for my equipment was in the back of the room. The shortest way of routing my cables makes them about 60 feet long. I am getting mixed answers if it will be a problem or not. I am still a few weeks away before I will actually be able to test it, but I was just trying to see if anyone here had an answer to if its going to be a problem or not.

    I'd say you want to try to increase the size of the wire to the mains, though you may not really hear a significant difference. Does it sound good now?

    This should more or less answer things in terms of length:
