Hi ,

for my outdoor speakers JBL 29A :

http://www.jblproservice.com/pdf/Con...es/C29AV-1.pdf

• High Frequency 2413H,25 mm (1 in.)
CompressionTransducer: Driver, Pure Titanium Diaphragm

The driver is dead - no noise at all ,
As check with Ohm meter - nothing.
I guess need to replace the diaphragm,
JBL does not supply a diaphragm for this driver and i couldn't find good diaphragm - all looks cheap alternative .

Can some1 recommend on good diaphragm?
second Q , in general - is the ferrofluid is recommended for all compression drivers?
Do u think it's necessary ?
