Hello Tom.
Yes it´s the VC wire that gets hot. The nearby magnet front and rear plate receive some of the radiated heat from the VC and help in shunting heat away from the VC. It seems reasonable since manufacturers have already designed air cooling as the main method to help cool the VC wire to go further and reduce the temp of the surrounding air. The greater temp difference between the VC wire and air should help and make up for the insulating nature of air. As you know the main failure mechanism of drivers especially in PA work is overheating of the VC wire. This also limits actual performance! In efficient horn designs this is less because of the greater electric to acoustic conversion. Nevertheless it also means that increasing the heat tolerance of drivers results in much greater benefit as my example pointed out.
My respects for your designs and mission statement!
