Random Idea: I see a few manufacturers over the years have offered aluminum speaker enclosures, for example GK (for bass) and Bogner (for guitar). I wonder if anyone has experimented with making a cabinet with an finned aluminum baffle board for heat dissipation purposes, similar to some automotive differential covers for oil cooling? Perhaps even going to the next step and putting heatsink compound in lieu of a traditional speaker gasket and then mounting it with T-nuts for a solid mechanical bond. My presumption is it’s not economically feasible or capable of efficiently dissipating heat as much as a heatsink directly on the driver’s magnet structure surrounding the coil. Either that or perhaps it wouldn’t make any difference for applications outside of super high powered subwoofers. What triggered this idea was a recent loud gig where I noticed my sealed Ampeg 4x10 at the end of the night was actually warm to the touch near the top of the grille from heat radiating off of the drivers. Being sealed, it doesn’t have ports to allow convection cooling, so the heatsink idea popped into my head. Maybe they just needed to turn up the air conditioning in the room. I’m just thinking out loud here. Thoughts?
