I am not quite sure about the fact that the 126A driver used a smaller spider, nor had a poorer bass extension?
Not that I'm saying you are incorrect, but my standard L-65 doesn't seem to lack any bass extension at all.
No doubt there are differences in the Driver, and X-Over Specs between the three models, the L-65 L-65A, L-65B, otherwise JBL would've never changed the model.
One should no doubt believe, and correctly assume that JBL back then wouldn't certainly go backwards in technology, later resorting to poorer performance within this speaker model, or any other of the speaker models of the day, and that the A, and B versions should indeed be an improvement versus the standard, first L-65 Version, correct?
I wonder exactly how much difference in frequency specifications there was between these models, and if the X-Overs made up for any lack in the original 126A Bass Driver? I gather there were some similarities between the three drivers, such as magnet size, basket size, and shape, voice coil diameter, but as you say, the spider may have been different, materials slightly different, etc.
No doubt the very reason why the recone kits are not interchangeable between the 126A, and 122A. Mark
