[Vintage-Audio] Re JBL Differences

[WBob]

The JBL company developed a very successful studio monitor, the 4320 
that was a big heavy box. Wanting a smaller product for small 
studuios, the developed a smaller one, the 4310 and with a fancy foam 
grill, moving the tweeter and mid back to the plane of the woofer and 
with a change in management it became the L-100 or "Century". It has 
a 12 inch woofer, 6 in mid and an cone tweeter. The highs suffered 
from the poorly placed tweeter and they changed to more dispersive 
tweeters subesequent versions of the L-1xx series.

The L-300 is a 15 inch version of the L-100, in a bigger cabinet 
although not the size of the 4320 and has the LE-85 mid and 077 
tweeter. I've never seen one.
