Magnet wire?
Holy Cow!
I have recently completed and measured the performance of a very nice piece of speaker wire.
This is more what you might call an anti-wire so to speak.
That is I only built for two reasons.
Number one is all the nonsense that constantly comes up regarding speaker wires often being very expensive, poor performing or ackward/unweildly and sometimes you even find a combination of very expensive, poor performing and ackward/unweildly.
The second reason is that Parts Express introduced a new Pro speaker wire intended for multi-amp setups which I could see had the potential to be an awesome single channel speaker wire.
Speaker wires like this...
http://www.partsexpress.com/pe/pshowdetl.cfm?&Partnumber=100-020Have exellent performance and aesthetics and are the best deal to be had.
Often boutique and DIY offerings cannot achieve this level of performance.
If you were serious about building a better speaker wire (that is one that actually has lower resistance and inductance) You could build this....
You start with this wire from Parts Express which is quite reasonable (for what it is) at $2.25/ft.
http://www.partsexpress.com/pe/showdetl.cfm?Partnumber=100-491Now separate the conductors four to + and four to - (red, yellow, brown and gray to + and blue, green, black and white to -) and strip the ends.
Twist all the strands from all four conductors tightly into one great big perfectly round twisted, stranded conductor (for both + and -).
Then heat the ends and feed solder from every direction until all strands are permeated and solder is wicked clear up under the insulation.
Cut the excess length from the end giving a nice flat end and use a file to file the solder away until you have big copper posts and polish with 400/600 grit sandpaper.
Speaker wire pants are not available (as far as I know, I tried the largest from P.E.) large enough for this wire so I formed the ends into a fork shape and dipped them five times in 'Rubberize It' tool handle dip.
What you have when you are done is a 7awg equivilant speaker wire with lower inductance than you would get from 7awg due to having four separate runs of wire.
The aesthetics are nice, everything is contained in one round black jacket and it is very flexible and limp (will lay flat after it has been coiled).
In the practicality department it is designed for pro use and again it costs only $2.25/ft which is awesome for such an extreme level of performance.
I connected it to my measurement rig with the amplifier end shorted to measure the total impedance it adds to the output impedance of your amplifier including the impedance of the connections at the ends.
I measured the loop impedance and exported it from LMS into LEAP and modeled an inductor/resistor combination that resembled the my measurement as close as possible.
The results are 13.5mohm and .55uh for an 11' piece (about one fifth what you would expect from 14awg zipcord).
Note the scale is milliohms and not ohms as shown on the chart.
