    i have right now 12ga speaker wire running to my mains and center. in a few weeks i will be setting up my front projection in my living room. The problem is i will have my mains & center sitting next to the wall. and that s all. i'm trying to hide the speaker wire.. i'm trying to eliminate the big cable. i was wondering if anybody knew of any smaller gage speaker wire that can carry signal like 12 ga wire? Or should i stuff the wire in the running boards on the bottom of the wall. all ideas would help.Thx

    Nope. Smaller wire will indeed carry the signal, but there will be greater resistance. With some speakers, this will make an audible difference.

    This is (not just) my opinion - you should never need wire larger than 14 gauge. Such wire is already an overkill in 99.99% of typical applications.

    It depends on the length of the run and the ohm load.

    Mike_S -

    I'm sorry for being the village idiot, but I got a little confoozed from one spot on that chart. It looks like the sweet spot from a simplistic wiring sense is to go with 5' runs of 16AWG into 8 ohms. No other distance, and not 14AWG, not 12AWG, and certainly not bare coat hangers bent to shape.

    Is it possible that one entry is a typo or is there something magical about that combination. And if so (as in, it is magical), then do you know why?

    Again - sorry for being the designated VI, but that one data point seems so magical that I'd be thinking of rearranging (and probably being divorced... ;-0 ) if it were true. Yeah, yeah - I'm know I'm pickin' nits, but every once in a while something like that is really real and makes me go hmmmmm.

    Typo... Sorry [​IMG] I will have to fix that.

    Edit: I fixed the chart. [​IMG]

    i bought some monster wire from BB, and installed it... then found out that it was only 16G. There are 3 runs that are 25 feet long (rear surrounds and rear center). Am I going to hear a sound difference (loss) if I don't change it to a heavier gauge wire?

    on a similar note, is it ok to double up on the wire (use 2 16G wire for EACH speaker terminal)?

    Absolutely it is ok to do that.

    Thanks for the chart edit, Dr. Spike!

    I was kind of guessing that (.50) might be the correct value but I sure didn't want to assume...

    Way, way back when I'd gotten a couple of 50' runs of what turned out to be fat MonsterStuff. No, I didn't go to buy that Stuff but the guy at the place I'd dealt w/ forever threw it in w/ a deal. I distinctly remember him saying I really just wouldn't need it unless I was going to have really long wiring runs. I always liked him 'cause he seemed so no-BS for hi-fi sales, and it turns out that he really was just that good. Now I'm using that pair as the run to my rear spkrs and using every foot of it without any really obvious or even measurable loss (and because I couldn't find coat hangers that long ;-).

    No problem.

    Yeah for the most part it wont make a difference and you would not need it.

    I got a great deal on 8 gauge. So that is what I use all the way around. More wire than I would ever need. [​IMG]

    Nice chart Mike that is where biwireing helps out on but thats a another thread.

    Mike.

    Here's a sort-of related question. I bought some 14 gauge and strung it up in the soon-to-be home theatre. I just recently got around to stripping the ends off one and noticed that the individual copper strands are much thicker than the strands in other wiring I've seen, or even the 24 gauge the system came with. Does the thickness of the copper strands have any effect on sound quality?

    Thanks.
    Paul.

    hey mike let me ask you something. let say i was going to build my house, and i wanted to pre wire my house for ht.
    would solid core wire work since it would be in the wall and is not going to be moved? i have heard it would carry a signal better. i just heard of people asking about prewiring their house but no one has ever asked about what kind of wire should be used. solid or stranded

    Paul, you will not likely hear any audible difference with different stand counts. Short answer, nope. [​IMG]

    Sheldon, both will carry the signal just fine. Whether or not there would be a difference to the sound, I would doubt it. I would say you would be fine either way you go. I am sure people will disagree as the cable thing is a big debate. [​IMG]

    Thanks Mike.

    Hmmm..I guess I could have saved a few bucks and used up the rest of that 14 gauge electrical wire I have left. Oh well...I'm sure I'll find some other use for it.
