How to select a good Speaker Cable


Speaker cables do have a significant role in how our system sounds. Different cables sound different. 

So which one is the right one for you?

The Speaker Cable is an extension of the Amp. and not an addition to the speaker's load. It shall have a certain resistance (low) not to spoil the Amp's DF figure. As so, it can be calculated and there is a formula to do it.

The higher the Amp's DF, the lower the Speaker Cable's resistance shall be. As today SS power Amp's get DFs of 400 and above (Digital Amps go by thousands) the cable of 10 ft (3m) long, gets as thick as 0 AWG.

I can see your eyebrows elevates, when that thick cable is to be deal with. Most Speaker Cable makers skip it because of that. So most cables on the market (regardless of the look or price) are of 14-12 AWG. Way less that supposed to be.

Worst! no Speaker Cable maker, dealer or seller knows the answer, of what is the correct cable for your system. 

So most of us ended up, with a cables too thin for the task.

A conducted test, on this site, about a year ago as well as with some closer friends, shows a significant improvement with a calculated size cable over their previous cable. The results were all positive and preferred the calculated cable.

So, instead of asking: which of two brands, or two prices or two colors of Speaker Cable do I need, you should ask how thick of a Speaker Cable do I need.

I'll be happy to provide you the calculation, for who request it. All you need to provide is:

1). Length (Ft. or meter)

2). The Amp's DF figure.

Thanks

a gauge LESS THAN means the wire is THİCKER.   The LOWER the gauge THE THICKER the wire

that is why in my flowchart  i said LESS than 10 gauge meaning the wire is THİCKER.

Sorry sir. A DF of 20 is so low that for 2m, you may use any ordinary cable (#14-#12 awg).
Mr. stevea11757

Thanks.
The best to make your 0/1 awg cable is to use a short but thinner cable on the ends. I used #8 awg. For the length, 10cn (4'') is good.
In person, I prefer banana plugs over spades. I used the Nakamichi type from eBay:

Connecting the short #8 awg to the Nakamichi banana plugs:
used soldering.
Connecting the  short #8 awg to the  0/1 awg cable: 
I use an industrial type of spade. I purchased a crimping tool for that size! and the spade is cramped over the  0/1 awg cable.
The connection between the short cable and this large spade can be done also by soldering (before crimping). You ,at yose alo a different methode:
Dril a short jile, for the  #8 awg cable to enter, about 2 cm deep.
Insert the  #8 awg cable into that hole.
Use a small hose band to tight it up - and you are done.
An isolating sleeve (shrinking) would be nice on top of that.

Please be kind to update me on progress, as well to share your impression from your new sound. Thanks.

For symmetry, try to keep both cables for same length,
even if one is a bit longer than required.
Speaker's data is not required.
They are not a part of this "Speaker Cable" calculation.

For a DF of 150 and 6’ it should be a #6 awg cable.
