FWIW, GPA is considered to produce the nicer of the diaphragms for altec drivers, as they have the tooling....
and they will install and remag Alnico magnets for 'free' when you buy the
diaphragms if you mail them in for service...
also good to note that GPA seems somewhat notorious for not really being
the best at answering their emails... phone calls seem to do much better
at their shop from my understanding....
