Need advice for renew JBL L300

Hi all,

I have L300 speakers which I really love,
But due the age I think i can get much better sound if I renew some of the parts,
Starting the LPADs which currently they are quite noisy .
Far as understand I need 16ohm and 8ohm but not sure what to buy.
I found these ones:

and for the 8 OHM:

In addition i'd like to renew the croosover but need advice where to start?I'd like to focus on the critical parts that is recommeneded to replace and just rebuilding the crossover.

Thanks you all!

That there are few if any modern speakers made with L-pad attenuators should say lots about 'em.

My panels have jumpers where fixed resistors can be installed. You could do similar and have a place to jumper in resistors to lower the HF output. Though why would you? Setup makes a huge difference.

You should be able to clean them with Deoxit spray(from the inside of cabinet or you may have to remove LPAD control alltogether and take it out(?), and just keep working the control back and forth with a flat screwdriver... my original caps in my L-200's work fine so I don't think all the hoopla about capacitators in speakers going bad is all that big a deal... 35 years and these crossovers still sound fine to me... ?? but you could try calling Madisound and asking for their advise, they sell speaker builder parts and helped me with replacing my Spica tweeters years ago.
