1 New pot, potentiometer, L-pad, volume control for JBL crossovers using a variable control on the high output. The unit in black is the new pot, the other is an original JBL for comparison and is not included with the sale.

The new units threads are metric and will require the use of the new hardware supplied. Comes with 2 nuts, 1 washer, 1 lock washer.
The new unit is 5/16" longer and will stick a little further out of the back of your crossover.
The shaft of the new unit is .015" less in diameter. The knob fits fine, the set screw threads in a little deeper.
The new unit has the same 1, 2, 3 markings on the solder lugs as the original which makes switching out simple.

These fit in the N7000 style crossover. If your crossover looks like the N7000, it will work. 
Note: Will not work in the LX80 and LX80a crossovers.

We offer services to install these if required.
