quick question. im wondering what the best way to loop excess speaker wire from teh reciever tot he speakers is. On one side of the bedroom my 12 guage wire was a length of 35' in order to loop it all the way around along the baseboard. the problem is the rear on the other side is very close to the amp, like 5 or 6 feet away =P so i have about 30 feet of excess cable to loop up. I remember reading that just doing it in a circle and using a zip tie can cause interference in the cable, is that true? if so whats the best method for me to coil this up? right now i just did the zip tie thing so its a flat loop

go past the speaker and return back or cut the excess - hope you didn't buy monster or some other over priced cables.

Cut the extra wire. There's no reason to have 30' of extra wire.

 

[RoboRay]

Yes, cut off the excess wire.


If you're worried about keeping your speaker wires the same length to prevent the audio from getting out of sync between speakers, your distance difference would have to be around 10,000 miles to result in a noticeable delay.

really? i had been told you want to keep them the same length. no i got it from monoprice. Hmm well its already hooked up i just got a big spool in the middle


how bad is just coiling it and tying it up will that lower the sound quality, or possibly cause humming (i dont hear any humming)

Keeping them the same length accomplishes nothing. Current travels through copper wire at a substantial fraction of the speed of light. So unless you are dealing with things that have to be timed to the nano-second, it isn't going to make a difference. If you are, I hope you aren't building a particle accelerator, otherwise the men in black will have to come after you.


Having an extra 30" doesn't really hurt anything either, but it does very slightly increase the resistance and capacitance of the wire. So while you can leave it there and not have it hurt anything, it is considered undesirable.

its actually more like an extra 20 feet or so =P What exactly is looping the wire suposed to do? i heard stuff running parallel can cause interference int he line or something but i dont think i notice any noise. does it degrade the sound quality? right now i just looped it around and tied it with a twist tie so its flat

I have never seen anything that would indicate cable length matters. I think people worry too much about such unimportant matters.


As for interference, I only worry if I get audible hum somewhere.

I meant feet.


An antenna is basically a length of conductor. So a long run of a conductive cable is essentially an antenna. Twisting wires around each other is a method of helping to cancel out this (it's what your typical ethernet cable uses), but I'm not sure exactly what coiling it is supposed to do.


You aren't going to notice noise from this in any case unless you are exceptionally close to a powerful transmitter, or have some sort of a flaw in your setup/system that makes it sensitive to such things.


The high end in audio in large measure seems to revolve around creating imaginary or at worst theoretical problems that can then be "solved" by some piece of hogwash. Most of what you've been told previously seems to fall into that category.

No.

Twisted wires don't cancel out anything.

The conductors in a balanced (differential) interconnect, such as a balanced audio cable, DVI/HDMI, or ethernet, are twisted together to ensure that noise is induced equally into both conductors, so that the differential receiver can cancel out this common mode noise.

Does it make a difference if you use two different brands of speaker wire as long as they are the same gauge? I have some left over from another room and I wanted to add another speaker (6.1 to 7.1) and I wasn't sure if this would make a difference or not.

I know it's not that simple, I just didn't think he needed an explanation of the standard.

No it doesn't.

what does he think though?
