Our reconing system is different. The myth exists that any little bit of 'rub' of the voice coil on either the pole or plate will immediately sound off.
Inspections say it's not true. Just take a kit and rub it lightly on either metal surface. You hear nothing. I believe that these constant 'rubs' are designed in - to use the pole piece .005 clearances (in 18" speakers) as a piston guide. The tossing around and bumping does contribute to magnet shift and progressive gap misalignment. Our recones with clamps are engineered to vastly reduce such older design defects. Then your brain functions with music like intended with positive feedback! Some of the good old You-Tube videos that used to show a bass guitar into a D130 and D140 have been removed. The D130 has a distinctly metalic sound. The D140, a bass speaker, has a stiff front suspension which is the only difference and sounds more restricted. This is 'old hat'.

The workbench below shows one common reason why you may want to buy our accouter parts for JBL speakers. The first problem is a landing that varies in height from 0.156 inch to 0.195 (nominal is 0.195.) Secondly a picture shows measurements taken from the bottome of the frame to the magnet top plate. The frame casting varies in thicknesss on this part and is oriented so that the errors add to each other making a total deviation from one side to another of 0.075 inches.
