Hi All,
Here's one of my DIY effort at speaker cable. This is 3 meter cable as this enough for me ! Pics of the measurement taken from Phone cam Please bear it ( hadn't bought the digicam then)
The Cable is based on the twisted pair design but after lot trial and error and after lot testing with various pattern of braiding this is one which gave me the best result !
The main problem with the twisted pair cable's are the Figure of eight problem ( I think you already know this),so tried hard to avoid this by using 3 pairs of wires.
I have used 6 16 gauge pure Copper with Silver coating each capable of handling 6-8 amps of current, So the total of 36-48 Amps of current Each Cable is capable off !
Another main problem of DIY cable is the inductance and capacitance, if both are not kept at bay ! well expect some fireworks baby ! So I've managed to keep both under control..As least the Values as much better the result !
The Value's are as follows :
1) Inductance for 3 meter is 0.011 Mh
2) Capacitance for the 3 meter 10.30 Mfd
Consider this and also compare this with commercially available one's
Just to give a few examples, Kimber 4 TC is 44 pF/ft, 8 TC is 100 pF/ft, Cardas Quadlink 5C is 23 pF/ft and the Goertz starts at 500 pF/ ft and goes up from there !!
As with Inductance they are almost similar in range of .345uh /ft to .715uh/ft ( small change here and there from brand to brand)
So I think you get the idea ! any doubts or questions, you know the drill !
I've attached the pics ! so Enjoy my friends !
Regards.
