solid vs stranded wire, get in here smart guys

[STEvil]

Voice coils are made of solid wire, only way to crack it is if its lose and able to move or you're running enough power and a certain frequency to make the wire physically vibrate.

I think it comes down to your connection. Either you do it tight enough to "crimp" the stranded wire into a cold-weld, or you dont and you lose efficiency.

Stranded wires are not immune to breaking from vibrations or whatever else may cause them to do so, they break inside the jacket too and cause breaks in the current path, after all they are just a bunch of small solid conductors wrapped together.

At our frequency and wire lengths I wouldn't even worry about skin effect.

Sure, you can use solid wire for speaker connections.

Robola46 did in his build.

Buss bars are solid and look how often they are used, regardless if its mainly for DC. There are still buss bars used for connection coils together and whatnot.

Solid copper wire is just difficult to route, bend and terminate.

Plus if bent repeatedly in the same place, it will weaken and break.

It will conduct better but I doubt it will be worth the hassle.
