I make all of my own cables.  I use 12/4 or 12/8 SOOW. It is a hassle to use the SO instead of SJ, but I like the heavier sheath. 

I don't like rolling up all that extra rubber, the weight, the extra size. I work alone and less rubber on my cables means less work. SJ has the same copper as SO and weighs about 20% less.

I have made all my own for the past 5 years or so. 
SJ 12/4 or 10/4 as short as possible for FOH.
SO 12/4 for monitors because it seems that no matter how well I hide monitor cabling, some wandering minstrel with oversized shoes seems to be able to pull them out and step on them.

When you make your own, you know that they are wired correctly and you have the resources to repair them as necessary.

When using stranded wire, the more strands = the better!
Better for flexibility, but less durable where it's going to be run over by stuff (dollies, carts, people, vehicles). Also, more strands tends to equate to higher price.

Well I guess from what a lot of you are saying, I should just buy some cable from my local supplier, get some ends, and make them myself.  I'm fine with that.  Thanks for the input guys!

I'm looking at going 4-conductor speakon connectors with all my speaker wire from my amps, to my cabs.  My question is this.  Is it truly "better" to go with pre-fab speaker cables and connectors, or just to go to your hardware store or electrical supply company and get 4 conductor 12 gauge wire, and some speakon ends, and put things together yourself?
Just thought it might be worth pointing out that nothing said seems to identify whether this a portable or installed and temporary versus permanent application, which could be a factor.  Just be aware that everyone seems to be assuming a portable, temporary application.

Transmission quality of a speaker cable is irrelevant at audio frequencies. Don't believe the hype.
If you are referencing factors such as skin effect I agree, but issues such as line losses and high frequency roll-off do seem to be 'transmission quality' related and can be relevant.

Agreed.  I think that a large number on this board automatically assume portable situations when a question is asked.

However- if you look at the real numbers (at least from the loudspeaker manufacturers I have talked to) a large majority (typically 60-75%) of their sales are for the install market.  The "glory" comes from the tour side of things-but the bread and butter comes from the install market.

So it is important to clarify what the particular usage is.  For example- I would not suggest any type of rubber jacketed cable for an install in which the wire has to go through conduit.  Throw a couple of bends in there and you are in for a rough day.

And of course the length of the run and the impedance of the load can greatly affect the capacitance and size of cable required.  Installs can easily be several hundred feet in length, where the type of wire does start to make a difference.

As Brad was eluding to-I don't remember anything stating the length or impedance of the load in the OP's particular issue.

Just another example of why  details are needed.

Don't skimp on connectors!  It's great to find bargains, but it's not a bargain if the connector fails. don't be fooled by Chinese knock-offs of Neutrik connectors.

We make all our cables including XLR's

With making your own cables you can also put a label covered by clear heat shrink on them

Company, length and wire gauge are what we go for. Colour coding for length makes life easier in quick setups as well

You may not know who Nelson Pass is but he is the real deal in
design.   Here is a good informative article in PDF form on speaker cables.

This is a poor example of how anyone should conduct tests. The first problem I noticed right away was the "impedance test." This is not how you do this. All he has done is measure the ability of the test instrument to drive this very low complex impedance. You must buffer the test generator from the load.

There are no calculations to show whether or not he is getting the expected results. Why? All the electrical characteristics of each cable are known. It is a critical step that was left out. Deliberate?

There is no list of test equipment used, so recreating this test, done properly or not, is impossible.

There are many more problems with this paper, but I am not going to waste my time with it.
