Not all JBL's sound alike...
...Nothing sounds like JBL. Nothing.
Which is exactly the problem. Just because nothing sounds like a JBL (including their own models by comparison), doesn't make JBL the definitive product. I own, personally, 2 pair of L88's and a pair of L3's with the latter clearly being superior, with no surprise of course. However I'm keeping neither. Overall they aren't my cup of tea. Impressive in some respects, to be sure, but overall not meeting my listening requirements or tastes. One thing they both share in common is too forward. When positioned just right the 88's image very nice for vintage.
Now, these are not respective of all models of JBL's, without a doubt, but they will command prices that are, honestly, overpriced for what you get. A Paragon is another poor example of value as most posts I've read didn't favor them at all, or very little. But these speakers are a statement, more than about execution. It was a demonstration of the effectiveness of a design, and implementation of art, in a sense.
I don't think the OP is out of line for his opinions or his questioning "value". Those who were offended clearly chimed in with little regard to the meat of the subject, which was not a blanket statement across all models of JBL's but a particular line or type of JBL. Nothing was stated about higher end JBL's, which dollar for dollar are likely fair prices compared to other similar status speakers, new or vintage.
The fact that JBL's were so widely used in recording studio's, mostly of course the 4300 series, somehow made them the defacto standard for listening. Unfortunately the demands of a studio are very clearly different from those of a typical home environment, hence so many makes and models of speakers to choose from.
Is it unfair to label all JBL's? Certainly. But should all JBL's be priced according to their notably better speakers? Heck no. There lies the dilemna.
I've owned 4 classic (vintage?) Mustangs, currently a 69 coupe. At $600 or $100k a vintage Mustang is a vintage Mustang. The rare exception being a Shelby, which is hardly representative of a typical "factory" Mustang. For the same money there are far superior vehicles available, including the latest round of Mustangs. It's Nostalgia, pure and simple. Anyone who tells you it's because of performance, handling, economy, is lying through their teeth.
Oh, I clearly do NOT hate JBL's. I have some LE10's and PR10's and would like to build something like the L77's. JBL made some awsome drivers, to be sure.
