I picked up a pair of JBL LE111H drivers who where supposedly restored by a pro.
The spider and surround are replaced with new parts from MWA. cone and coil are oem.

The problem are that these do not measure anything close too JBL`s published specs.

FS are 42-45hz (should be close to 30hz)

The surround seems to be too stiff, but are they the only problem? or can the spiders be a part of the problem?
(the only 6,7" spider for 3" coil in the MWA catalog are of B stiffness and should be pretty soft)

I can try too replace the surrounds with a pair from Rick Cobb, but irritating enough, it would have been far easier if I bought drivers with rotted surrounds, instead of these with their new MWA abominations
