JBL L-300 Summit Are they still any good?

I just picked up a pair of JBL L-300 Summits.
I am looking for some information on the L pads and crossovers. I’m looking for some input on where I could possibly pick up the correct L pads. Any positive feedback would be welcomed

Thanks for the response. I removed one today pulled them apart and cleaned them thoroughly with Deoxit D5. Definitely a huge improvement. Tomorrow the other one comes apart. Definitely going to recap the crossovers. I’m not quite sure what caps I’m going to use. I want to keep the same values.

The Hegel 590 seems to drive them pretty well.

I definitely will once I get the other L pads cleaned up.
great care is being taken not to damage the consecutive serial number foil cals. With all the L 100s I’ve restored I definitely have it down to a science.

Thanks for the information. Do you know how I can find the new replacement diaphragms ?

Thanks for your information pulled the other speaker apart today. Just fired them up! For old cap’s they still sound good. I have done a lot of business with Madisound with all my L-100 restorations. I still have a ton of the LE 5-2, mid
LE 25-1 tweets and 8 123A-1 and -3 woofers. I need to start unloading the extra parts. I watched a interview with Nelson Pass he said he may have improved the L 300 crossovers a bit but still felt  JBL did an excellent job on the configuration.

Lansing Heritage has a wealth of knowledge. I am just so busy listening I haven’t had time to even go on the site. I bought these at an estate sale from the original owner. I am not quite sure how common consecutive serial numbers are with the L 300 but these are consecutive serial numbered.All the drivers and components inside are very close in serial number.
The cabinets are in pristine condition not a mark on them.
