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!

I would just have the 'L-pads' cleaned, they are high quality ALPS pots so they are already high quality... JBL also used good quality caps in the crossover so you could leave those alone as well or experiment with some high end boutique type caps.. I have a pair of L-200's and what I did was replace the input connectors/jacks on the back with something high quality and then replace all the interior wiring with better wire.. could be of your choice.. I think that was the stock 'weak point' of the jbls was the internal wiring and the input jacks. Regards and have fun...
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.
