can the 2450SL diaphragm be put into the 41 driver without modification?
I believe there was a post last year about this, and while the diaphragm can be fit into the 41 driver, it must be shimmed to have the voice coil properly situated in the magnetic gap.
I would be interested in trying this, but it isnt plug an play, it requires a scope and a skilled person to do it. I could learn myself how to, and theres a possibility of doing exactly this when and if aluminum really is no longer available!
