Speaker Cab Cables - Wire Question

Awesome, thanks for such a quick answer. Much appreciated.

Yeah you want fat enough wire gauge to handle current without losses.

respected cable but if you put it in the walls your probably in violation of electric codes. The Canare 4s10Fand 4s12F are install cables but still need to be in conduit.

Anytime you know some of us are Uhber geeks

This where esoteric cables get tricky I know of way to many build outs where a sales guy has screwed the pooch by looking at his or her commission instead of the clients need ! Of coarse a couple of million in insurance claims and years on the road dealing with a different inspector every day taught me to always dig deep and ask the stupid questions! As a a former sales dude I never wanted to hear I screwed up by costing a client his insurance claim. Hell I made a lot of money because others didn’t dig deep and do their due diligence!

And to think it was only after retirement I started to hang with lawyers.

I've used Romex as speaker cable a few times just because I had some and had some connectors. Worked great despite being a bit unfriendly to moving it around.

A lot of vintage guitar cables were little more than lamp cord quality. Some might say that the loss of the cable had an effect on the sound and might have added to the tone. We (collectively) will do things like add a variac to brown out an amp for tone, why not use some undersized cable?

And yes, before someone says "but it's not rated for my amp's output!", amps rarely reach peak power. They also do so for very short amounts of time. Conductors fail due to heating caused by resistance. You can cause a conductor to fail by sustaining the power at a failure level over time and it build up heat and then eventually overheats, or you can fry it with a sudden surge of energy that overheats it immediately.

Guitar amps simply can't supply enough current to burn cables.

Why does romex need shielding?  You're more likely to pic up noise ingress from 60hz through unshielded cables plugging into your gear, or from adjacent gear, than unshielded cables in the wall.

Yeah, but in most studio builds it always seams like metallic conduit is a victim of running over budget, then the guy at the local music store cuts the cable budget by thinking he can put some generic stage cable in the wall. It should get caught during inspection but of course it’s a build out in somebody’s basement or garage and nobody ever pulled permits. Of course I type this as I look out the window at the KC Sheraton better known has the Hyatt worst unintended US building disaster in history.
