View Full Version : JBL 4410A's
Hi,
I'm wondering if anyone has any information regarding the JBL 4410A crossover. i.e. Crossover Scheme etc...
I'm looking to rebuild the crossover.
Thanks.

Dear Sab,
Here is the link to the schematic in the forum. I have a hard time remembering where they are, but found them for you.

Write more to ask for help and advice!
Scotty.
That helped.
Do you have anymore information regarding what parts I should replace. I use these speakers specifically and only for mixing my music in my studio. The reason that I want to update the x-overs is that I want to ensure that the speakers are performing to there maximum.
They are very important to me.
Thanks for your help in advance.

...most folks update x-overs by swapping in (1) new capacitors (caps) that often leak and change their values with age, and (2) attenuators (volume controls) . ...apparently, most of the other components like resistors and chokes don't change with age, however...

I personally do not know of any "age related failures" in any of the caps in these xovers.
I am sure that other high end caps can be swapped for the OEMs, but I have not done that.
I have the L110's that needed some l-pad work, but I did not change anything else. I come from the "if it ain't broke don't fix it" camp. Although I understand your desire to make these 4410's as good as can be.
Hopefully, others will chime in and advise you more correctly than I.
Good luck!
Scotty.
I spoke with support last night and they mentioned the same thing. The crossovers were built well and there really isn't a need to replace anything on them unless it isn't working.
I'm going to leave them as is until I need to do something.
Thanks for your help.
