Magnet Wire Question


I've decided to try some magnet wire as speaker cable. I'd appreciate some help.

Is 18 ga heavy enough for a 10' run?

Do I twist two lengths and use one of the twisted leads for positive and one for negative? Or do I need to keep the legs separated with painters tape or something similar?

Any other info would be appreciated!

Thanks in advance,

Gary

If you're talking about using bare wire and using the painters tape to insulate/separate the negative and the positive runs, I would advise against doing that.
It probably won't behave in as neutral/accurate a manner as a heavier gauge, but you may or may not find the resulting sonics to be to your liking. Some folks even prefer the sonics of 20 to 24 gauge solid core speaker cables, although IMO such gauges are likely to alter the sound considerably when used in conjunction with most speakers, unless their length is very short.

The lower the impedance of your speakers, the greater the departure from neutrality/accuracy is likely to be.

Assuming the wires are insulated, twisting them together, say a few turns per foot, will reduce inductance and thereby minimize any upper treble rolloff that might otherwise occur. The lower the impedance of your speakers is at high frequencies, the more important that will be.

Rax, thanks, they are enamel coated, thankfully. I read about spacing runs in a thread- may have bi wiring based comment.

Al, the speakers are Usher CP6311. (87 sens and a nominal 8 ohm load)

If thicker gauge would be better, I'll buy it. What gauge do you recommend to insure I give the magnet wire a fair shot?

Also, I heard a suggestion to use an electric drill to twist the wires. Is that the best way you know of?

Thanks guys, I appreciate the help. I tried some solid core in a woven jacket and it opened the sound up over the stranded I had in place. Curious what the minimal coated magnet wire will sound like. I tend to prefer lean over thick sound.

Best-
