hello
I am in possesion of 4343 recently
they function perfectly except for a detail
my living room is very reverberating and, when I want to decrease the level of the high frequencies, the potentiometer is noisy when I actuate it.
in fact I realized that the potentiometer acts almost as a switch.
I would like to change them.
on the diagram of the filter, it is indicated three l-pad, two of 50w-8ohms and one of 50w-16ohms

the only ones that I found and who seem to correspond to those of origin are on the Web site partsexpress

ref 260-252 and 260-254
it's good or I made an error?

Welcome Jaques

Yes, the only place you can buy the 16 Ohm L-Pads outside JBL is Partsexpress.
You can also contact your JBL dealer. They are still in stock but expensive. I remember 25 Euros each.

Oh, the 3143 network has two 16 Ohm LPads and one 8 Ohm LPad!!!!
