At the risk of getting a good forum kicking, is there anything wrong with simply using more cabs?

Surface area is your friend here, forget using 15mm plate (from memory the punisher is a 15mm cab) the cost will cause heart-ache, 6mm would be fine, you can cut that with a jigsaw, or a router if you so carefully, personally I would get it laser/water axed and have all the holes done too so they just need countersinking!
 
Once I took delivery of the plates I would bolt as many of these kinda things all over the inside as I could fit :-
 
 
Quite obviously get shut of the fan/clip/cable, use a bit of common sense so the don't foul the driver!
 
Drill and tap the base of each one and use at least 2 thread-locked (loktite 648, don't play about) M4 stainless counter sunk screws to hold each one, use heatsink gundge on the contact area and spray the inside matt black!!!
 
Hit up a local computer repairer for a load of heatsinks, they get binned all the time...
 
Ideally you want to do similar to the outside of the plate, but that would be silly!!!

I've often wondered whether the plates in the Pun make any real difference, do they? I've seen commercial closed designs with a proper heat sink - surely this would be better.

... really large jerry clip and some heat pipes?

the plate and magnet would have to physically touch for it to be effetive...

There's nothing complicated involved, just fabricate some plates and drill them as required. Put some gasket tape on to form an airtight seal and bolt 'em on. Might as well make thickness as the cabs.

Now if you want to get serious a way to thermally connect the plates to the driver magnet rear would be interesting. Else you are relying on the thermal conductivity of air, maybe that isn't such a big deal though.

Hi all,

Our last ciare drivers have over heated, I want to put aluminium plates in the next build to attract the heat away from the driver magnet or speaker compartment. 

How do you create a D.I.Y aluminium plate. Does the plate need rivets, If so what for?

Any info would be a big help as I want to run our drivers at 1000w for a long duration of time for festivals and outdoor events. 

Thanks
