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

They are wonderful speakers. Do a google search for lots of information.

The capacitors probably should be replaced in the crossovers
If you know you like the classic JBL sound, they are a great choice.

If you're not familiar with the JBL or "west coast" sound, then you'll want to give a listen to some examples before you commit.

JBL has a strong following for their very characteristic, punchy quality but not everyone is so taken. Tube amps are a good choice. Some solid state amps (especially the transistor ones that were popular 20 and 30 years ago) could sound extra strident.
JBL's rock, period.

Hell most of the rock music made in the 70's used some kind of JBL to mix the albums in the studio. Mr. Townsend himself commented on how good the big 4350's were in mixing Quadrophenia.

Wonderful classic speakers. Loud and Proud!!!!

55 & 57 Chevies, Airstream Trailers, Bamboo flyrods, and big JBL speakers with classic mac tubes. HEAVEN!!!
