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

Drop in replacement = JBL 2216nd. It blows away the original 2231 or 2235 hands down! 
I think he made the statement that they were his favorite back when they were current. He redesigned the crossover for the L-300 some years ago. Got rid of the auto former in the mid-range circuit and changed the tweeter section to a first order instead of a second. Other then that, as he stated, JBL crossovers are hard to improve on in their large monitors, which of corse includes the L-300 which is just a 4333 in a home friendly cabinet.
