People have revisited 4310/L100s and found exactly what you
described - really pretty good drivers but too-simple and naive
crossovers.

Yes, a pity that they did have some clues like conjugate capacitors,
but often spent more money on the aluminium boxes for many of their
Xovers than the rest of the parts.
Of course they weren't alone there, KEF's of the same vintage are
also improved by adding better Xovers, as are quite a few others
with good enough drivers to bother.


That is really interesting. How is the enclosure design? Does it
support really
good low-end from these drivers? Because the original speakers had
"big bass"
but not really very deep bass.

That's pretty relative. You could certainly get deeper bass from a
12" woofer if you wanted, but they still go deeper, louder, and with
less compression and distortion than smaller systems.

That doesn't really answer my question. The original JBL "4300" series
studio monitors thumped out a lot of midbass. It was loud, it hit the
listener in the pit of of the stomach, so at mid-bass frequencies,
these speakers obviously moved a lot of air. but they had little in
the way of
REAL, deep bass.

I was doing a lot of recording for NPR at this time (I was the
recording engineer for their "Jazz Alive" series, among other
projects). Anyway,
KQED-FM had JBL 4310's in their editing studio and I used it
extensively
to put together the "Jazz Alive" location recordings that I made all
over
San Francisco. Once I was required to record a pipe-organist at the
huge
Grace Cathedral on Nob Hill. I took the 2-track/15ips master back to
the
studio to edit it for broadcast (I wasn't a KQED employee, but the
producer was). I couldn't believe how poor the organ sounded on those
speakers and
was scared that something had gone wrong with the recording. So, the
producer and I grabbed the tape off of the studio Ampex and took it
to my
house to play it on my AR-2ax's. There was nothing wrong with the
recording (the bass was spectacular), but the JBLs emasculated it of
any real low end.

So, my question is, do the modern, improved crossovers fix the bass
problem?
I suspect not, but if anyone knows, I'd love to hear their
experiences with these speakers.

Your experience is unlikely to be due to the crossovers. If a driver/cabinet
design doesn't provide low bass the crossover can't add any.


Well, that was pretty much my point. Mr. Kruger (and others) talked about how modern crossover design has taken these speakers from
their original poor reputation and made them acceptable sounding. My point was if those modifications didn't fix the bass, then there was little to recommend going to the trouble of retrofitting new crossovers as they can't fix one of the 4300 series most fundamental problems.
