Heat problems!?

Dave's always been a hard man to move.

Has any one thought about the Volt Driver where the frame is on the outside of the cab and not enclosed as other drivers are? Though that does depend on how much air travels over the frame to allow it to cool.

JUst a thought!!!!

You want it when?

But you have to remember that for the heat to get into the magnet assembly first and hence to any connected structure it has to pass over a tiny but very important Air Gap.

Regardless of how many claims are made for advanced cooling of voice coils etc this fundamental weakness in the thermal flow cannot be overcome, at least with traditional methods.

Physically cooling the air in the cabinet to sub zero temperatures would probably make some difference but even then less than you would think.

What probably causes most of the early onset of thermal damage in the Punisher is simply that the movement of the cone is much smaller than normal due to the increased cone loading so that for example cone movement is probably 1/4 (Guess) what it would be in a reflex box.

The fact that it is also working in a tiny chamber acerbates the problem so that the poor air ventilation becomes extremely poor ventilation so the driver fails with seemingly less power than in a traditional box.
That said it is only probably 10-15% difference in the two scenarios.

Answer, simplzz, use two Punishers and only stick 500w up their arse's because you ain't gonna cure it with bits of "tin" no matter how clever you are.

Water pathways through a cast aluminium frame would make sense... if necessary

many water cooled Lazers were used and it wasn't unusual to find bucket loads of water back stage, so sooner or later connectors give trouble

Neutrik to release a line of hydraulic fittings?

NOW IV NEVER HAD A DRIVER GET HOT ENUFF TO KNOW.... DOES THE WHOLE DRIVER GET HOT? EVEN THE FRAME?

If it sounds like a gorilla is trying to escape, turn it down.

wat about a heat exchanger?

...i mean putting a "large" radiator inside the chamber with heat pipe running out side to another radiator with a 140-200mm fan.

a similar effect to how computer heatsinks work but on a larger scale. it could work quite nicely but would need some extensive testing.

im talking about cooling the air inside the chamber not the magnet. i.e lowering the ambient temp inside the chamber by a few degrees....... and the few degrees can be the diff. between a cooked coil and a hot coil.
