I have this idea about driver design. It might not be a completely new idea, but I think it has some kind of potential.
I always wondered why not reduce non-linear distortion and cone flex and increase power handling by making the voice coil the same diameter as the diaphragm. Move the magnet to the inside of the vented pole piece, where an aluminum heatsink could benefit from the air that moves in and out as the diaphragm moves.
I think this is easy for a small midrange and midbass driver, but get above an 8" and sure, its not so easy, but still could probably be done. Personally, I like 8"s. I'm also a fan of a lower Fs and long excursion, even though the trend is to go with a really stiff suspension to handle the high power, which is counter productive, because now you need to use all that power to get some low end because the suspension is so darn tight.
Anyway, just throwing that idea out there to see if anyone can run with it or suggest how it might not work.
