JBL L300 - true myth?


I'd like to ask if some can write his opinion on this speakers,I had a chance to listen and recommened .
I understand they working great with powerfull tube amp...especially with Mcintosh -is that true?
it's look the components are really good Alnico drivers special tweeters,horns...but woofers made of carton?is that a problem with today standards?
Is the old fashion crossover need upgrade ?

Thanks

As a kid, it was always my dream to own a pair of L300’s. I would love to pick up a nice pair today. The smaller L110 and L65 were nice too.
I just picked up a pair of L300 and L200 at the bargain price from a local audiophile.  They were quite abused and damaged outside and inside as well.  But they look wonderful from at least 20 feet away.  I have listened to both L200's and L300's with a little Pilot tube amp. They sound fine but not the greatest I have heard so far.  They are not perfect. They have some strengths for certain areas and weaknesses for other areas, like our children. I will try to enjoy them while refinishing the cabinets and cleanup the mess inside. I have to live with them for a while to learn more about them. My first impression is that they have more strengths than weaknesses. I would like to enjoy their strengths more than their weaknesses.  At some point I am going to pass them on to someone else, so that they can experience what these are. Happy Listening!
The JBL L-300s were the best sounding JBL Speaker I ever heard.  I built some JBL Lancers with the 14" Aquadag coating LE 14A  JBL 5" Mid and 1" Pro Titanium tweeter.   I thought the Lancers sounded better than most sub - $1000 / Pair speakers at the time but the L300's were what I wished I had after hearing them.  The Lancers really put you into Pink Floyd's "The Machine" but the L300's were thunderous Majesty.   Top notch components throughout. Beautiful case work. Great everything.

Hello, has anyone seen replacement 15" woofers  in the L300 available ?
As like in Henricksound in japan.
