Inside cab wire gauge?

#3
16 would be good choice but Id go with 12 or 14 if I had it available. 18 is too thin imo. Doubling up 16 gauge would give you equivalent of 13 gauge btw. A lot of higher price speaker cable does that, combines wires of chosen size to create a higher gauge composite. The reason I suggest thicker is due to it being bass signals. Btw I use 12 gauge speaker cable for home stereo. Diff performs better then any 16 or thinner gauge Ive tried.

Use this to determine the gauge necessary:

Even with 50 feet of cable you cannot hear the difference between 12 and 16 gauge. That difference would be no more than 0.5dB, which is not audible. With shorter lengths there would be even less differential.

And its the easiest to hear and least expensive way to improve a systems sound bass wise, useing heavy gauge cable.

Sorry, but that's simply not true.

I geauss you never learned the truth about bass signals taking more watts and current. All treble based music uses very few watts compared to bass music. And its the easiest to hear and least expensive way to improve a systems sound bass wise, useing heavy gauge cable.

The first truth you cite is certainly true most of the time. It's undoubtedly true that a low frequency tone requires a greater amplitude to be perceived at the same volume as a higher frequency tone. Once you start applying this to the realm of "music" as some kind of abstract generalisation, however, there are far too many caveats that need to be applied to make it a useful statement. And the the last "truth" is just false.

Hey all, I'm going to be getting in and slapping a couple Eminence Legend CB158's into my 215 cab. What gauge wire would be best? 16? I'm replacing the speakers, the wire, and the 1/4" female socket.

And have you done the science to ensure that the CB158s will actually work well in your cabinet???? Read the FAQs atop page one for more information. Not doing so will just end in a crapshoot.

Use the largest and best cable that is practical and affordable for you and with high-quality connections. It really does matter because large current and voltage swings are required for bass speaker damping. Damping is how the amp controls any potential over-travel of the driver. Pro and higher-quality amps will often list an additional parameter: damping factor, this is a measure of the amp's ability to control the driver, higher is better. If you use small and/or low-quality cable you reduce the damping factor of the amp-speaker system, and they are a system and must work well together. This is one of the advantages of powered-speakers, they can be designed and implemented as a system when done well.

Myth, explained here:

Worst case, using 100 foot cables and tube power amps, the effects of damping might be barely audible. With the cables used with electric bass cabs it's a total non-issue.

The wires are short and need to be flexible for assembly and disassembly. Therefore, 16 or 18 AWG is fine. They certainly don't have to be the "largest and best cable," or 12 or 14 gauge. Larger wire could actually be detrimental in this application if its stiffness puts too much stress on the connections.

IMO, you should use the thickest mains cable you could get your hands on. I dont think interference gets into cabs, and at large wattages, it probably wouldnt make a difference when it did get in there.

That may not be fact, but it seems correct to my knowledge

Using anything of a heavier gauge than that required for the current load over the distance involved is wasted copper and cash.

A meter of cable can probably sort 3 cabs. Its only pennies difference :D

I got 2 meters of massive gauge cable for £1.50 at my local DIY shop.

Im sure ~20p difference per meter shouldnt matter too much.

I suppose it depends how many cabs you are making. :smug:
