whenever I see a speaker wire thread I run away fast... but just this one more question. I'm using 12 awg wire running about 6 feet to the FL C FR, and about 20+ to the rears, does this matter? Should all of the runs be identical length?

It doesn't matter. The signal travels through the wire so fast that any difference in length is completely negligible.

Different lengths is generally fine. I would avoid severely different lengths for the left and right speakers in any position -- for example 20' LF and 4' RF would be less than ideal. But different lengths for the surrounds versus the fronts is no problem. The most noticeable difference from a long run is that the channel might play softer. But you will adjust that out when you set the channel trims anyway (play test tones, use SPL meter and adjust all the trims so the speakers all play at the same volume level), so it is not a problem.

Yeah, don't worry about the differing lengths. The only reason I try to keep the lengths the same is because I don't want to cut them up in case I need them later for something else (I'm always moving and trying speakers in differing locatuions)

same here.


I have a different q regarding this stuff. My surround speakers have a detectable "hissssss" during HT enjoyment, and I have ameliorated this by angling them away from the listening position. It's not too bad, but I could notice it sometimes easily. Would improving upon my 16 gauge wire for about 30-40 ft runs make any difference for this. Or is this due to other things, such as quality of source, metal tweeter, etc?

The signal traveling via the speaker wire is at the "speed of light" or 186,000 miles per second. In other words, you have no worries and it is fine to have different lengths, even if your mains are at 4ft versus 20ft as Max stated.

it will probably be a low signal to noise in the amp or level is very high.

a lot of speaker mfg. will recomend 12 for runs of 30 and over.

Thanks for the reply oztech.


Any experience with a NAD T973?

Can you better explain why? Can different gauge wire compensate for longer run between L and R ch?

While plenty fast, it is not the speed of light.

Which depends on the medium it's in, right?
