My DIY Speaker Cable !

Hi All,

Been in this forum from ages but never actively participated for various reasons !! but now finally thought to give it a try (participating actively)

So here's one of my DIY effort,a 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)capacitance =0.013nf ( or 13pf for 3 meter) or 1.3pf /ft
2)Inductance =0.02mh for 3 meter or .002mh /ft

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 !

Another thing,This project was also posted in a Canadian forum where the Admin was Gracious enough to showcase this project in his Gallery with some Spice simulations and stuff !! so here's the link for those who are interested in this project !!
