Yes it will, and it seems to me that might be a good idea. The trick would be to make it in such a way that it can conduct heat away without fusing. Might also be good to use materials and fabrication techniques that promote heat transfer from the coil to the former to the cone and spider. Possibly these can be made to function as heat radiators. The proposed solution is attractive because it is easy to implement on existing speakers, and measurements show that it works very well at removing heat from the motor.

I just received the drivers.

Their's this nice well-built grill over the vent. I cant see going at a nice expensive with a pick to pry it off.

Nothing to it. They all have that mesh, but it's just pressed in. It is very easy to pop out.

It all sounded good until I got the speaker here...


I'm having second thoughts now, the value of the speakers is far to high for me (even taking the sandpaper to it...)


But I do have a peice of alumn. (enough to make 3ish) I'll do a bit of work on the horns (I still dont know the clearence) and then make up my mind. My boss brought up a good point, if you need a few made just send me some prints I'm real handy on the lathe (until you get your cnc setup) - Just a thought.

Maybe you would feel better buying a pair of inexpensive drivers to try it out on. Of course, the lower power models won't get as hot, but it will at least allow you to get the feel for what's required.

As I said in my last post, the mesh is only press fit in the vent. There isn't even a groove that they fit in, so the only thing that holds them is friction. I've had them come out all by themselves after a few years.
