my diy cables
« on: 19 Mar 2005, 01:46 am »
just built my first diy cables, breaking them in now. i used the marty dewulf recepie, lowes 6 awg wire, run with the writing in opposite directions and about one twist per foot. covered in techflex with heat shrink locking it down for nice appearance. i used big bananas from vampire wire at the ends. i chose bananas because these cables are very stiff and hard to position. replacing 12 awg magnet wire cables. the total cost between 50 and 60 dollars for the pair. i will review after some break in hours.

very nice! There's nothing like the pride of diy, as long as it sounds good and you remain objective.

I'm not intending to denigrate your efforts but, as a DIY cable guy myself, I'm interested to know why you chose 6awg wire for your speaker cables.  I'm assuming here it is 6awg stranded?

My reading up on cables has led me to believe that "fat" cables produce "fat" bass ... ie. if you want good-but-not-overblown bass then 0.9mm diam is about the max you should go which is 19awg (with 0.7mm diam better - say 21awg) so you would use multiple runs of this thinner wire in parallel to increase the overall guage.

Also, why did you put the writing in opposite directions?  I know wire is directional but, because the music signal is AC, I didn't think the direction of the signal path had to be considered as an "out and back" loop.

Regards,

Andy

i made the cables 6 awg because marty dewulf of bound for sound said these were the best cables he's ever heard bar none for 4 ohm speakers. reversing the wires was at his suggestion also. i suppose it makes the cable less directional but i don't know for sure. as far as a 6 awg cable transmitting a signal less accurately than a thinner cable, i don't know anything definetively about that either. the 6 awg cable has 19 strands of copper per conductor. still breaking in so sound has not been critically evaluated yet. these cables replace 12 awg solid core copper magnet wire. initial impression is that the cables provide increased bass and an increased amount of details. when i listened to vivaldis four seasons some of suumer, fall and winter allowed me to hear individuals on violin as opposed to a chorus of violin. as to whether a bigger or thinner cable introduces more or less coloration or distortion than a source, amplifier, or speaker i don't know for sure either but i am inclined to doubt it. i have a panasonic dvd player, b&k pre pro, sherbourn amp and aerial 10 t speakers. the sound is very good and the cables are being demoed for a marginal improvement.

I've been using the following described wires on the RM40 for several years now. This wire can be purchased at Lowe's or Home depot. It has been talked about before on AC. I have used most of the cables that you mention, and to me none perform as well as these. Of course, this is my own opinion, but for around $50 total you can prove me wrong - Watch directionality, and break them in by running for a week or two, taking them out for a few days, then put them back in. It works.

I hope this comes out right, If everything is blank below this, it didn't.

"The cable I chose and which performs so well comes in a variety of jacket colors - I used red and white. On the outside of the jacket is the following: "E51583 (UL) AWG6 CU TYPE MTW OR THWN-2 OR THHN GASOLINE AND OIL RESISTANT II OR AWM 600 VOLTS VW1". It's a 19 strand cable, with the internal wires having at least two different gauges (maybe more).
"Construction. For each speaker side you'll need two sections of the above cable. I used the red jacketed cable for the positive and the white for the return. With the red (pos), I ran the cable in the direction of the writing on the outside (reads from the amp to the speaker). On the white return (neg), I ran the lettering in the opposite direction (reads from the speaker to the amp). Then I put a very gentle twist on the cables of about 9 twists for the eight foot pair that I built. Repeat for the other speaker. Spades? Because the cable is 6 awg, they are pretty thick. I didn't have spades on hand with eyelets large enough to accommodate the diameter of the cable, so I trimmed it down a bit while spreading the eyelet open a little. When it all came together, I soldered it up and forgot about it. Don't sweat the kind of spades to use - it isn't going to make a huge difference anyway. After all this, you may find out that the cables sound better reversed - no problem, try anything you desire. Break-in takes a while. But, don't get crazy worrying about it. Let everything play out and you'll ultimately be happy. It has been observed that direction of the wire varies depending on location it is purchased - try it both ways just to be sure.
"This is an especially effective solution for systems using high power amplifiers into 4 Ohm loudspeakers. Don't think, however, that this cable will only work with one amp and one speaker - it will work with everything. Try it, the best speaker cables you may ever need may cost you about fifty bucks."
