Default Speaker wire

Some go to great expense on speaker cable but the wire in the speaker box is just some skinny thing what is good wire inside our speaker cabinets?

The wire in the coil is often even skinnier

Speaker wire
Most of the time it looks generic unbranded but it would be OFC and of good quality. If it is not made for audio, it will usually cost several times cheaper and might have better performance than msot audio cables. Military grade ones come to mind. Besides, as noted above, using 3m of $$$/m cable will eventually get you to the crossover where a 0.6mm coil made of solid core wire with length of 15-20m will be present, on most of the cheaper loudspeakers (that if you`re lucky for it to be an aircore).

The length of 'skinny' connecting wire inside a speaker cabinet is so short that it introduces an insignificant amount of resistance to the flow of current.

It is in the longer run between the amplifier and the speaker where the benefits of using a thicker wire to reduce resistance are obtained.

Using too thick a wire internally can cause problems in crimping or soldering the thick wire to the driver terminals as well as putting undue stress on the terminals due to the weight of the cable.

The only thing that truly matters is the end-to-end resistance of the wire. Short thin wires are the same as long thick wires.
The cable should be a closely spaced twisted pair or quad.

Cut up a loudspeaker and unwind the voice coil. That wire is long and SKINNY!!

You do need "better" wire TO the speaker so that the voice coil gets most of the power. But 15 feet of lampcord, or 2 feet of hookup wire, is not a big deal compared to the speaker guts.

Speaker wire
I use solid core 24g from the amp to the speaker (and inside the speaker). Thick is not necessarily a good thing. Amps. speaker and what connects them has to be considered as a system.

DC Cable Sizing Tool - Ensure You Use The Correct Sized Cables - Free Calculator
calculate dc cable thickness for length. not sure if its the right calculator for speakers.... but you can get an idea. see for ya self. why very short thin cable is ok inside speaker but depending on ohms of speaker and length, you need may need thick cable to connect speaker to amp.

For speaker cables thick is about the only good thing. However, beyond a certain point you enter diminishing returns so too thick has no real electrical advantage and may have mechanical disadvantages.

The system consists of essentially a simple circuit loop. You want to minimise the resistance by using thick enough conductors, and minimise the inductance by keeping the out and return conductors near each other.

There are difficult bits in audio. Speaker wire is not one of them.
