I am looking for the correct procedure to align the hi frequency cone in a JBL hi frequency driver. If anyone has done one, please post! Thanks!

Fred: no alignment. It must fit as made. The pins are quite tight making any adjustments impossible.

You could use a small amplifier and generate a tone sweep on the bench to assure yourself that there are no buzzed and rattles. 500 Hz and up at low level should be OK. Louis
