JBL L-300 Summit Are they still any good?

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.

Yes JBL was one of the top back then, older ones, 60/70. I'm sure the caps are still good enough. As you know, they have made some improvements in capacitors since these were made. Could have already been upgraded I suppose.

@iconicaudio,
You might want to check out the Lansing HERITAGE site you will get more info on all things, JBL and ALTEC. Yes, they are good. Mike

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. 

I clean my JBL very often. may be you have to do that toohttps://ludokingmodapk.xyz/
