Titolo: JBL L90

Ciao a tutti, da quando ho problemi in qualità di dj ho iniziato a postare
su questo news che però adesso mi affanscina e mi invoglia a leggere anche
post che non mi riguardano :)
Mi è venuta una curiosità leggendo tutti i nomi e marche di casse che
possedete o che vorreste...
Vorrei saperne di più su le casse che posseggo, dovrei potrei trovare info
molto specifiche??
Grazie
Anche giudizi personali sono ben accetti...

Per me casse da rock.
Per hifichoice:
 
I'm slightly ashamed to admit I can recall the original L100 Century
on which JBL's 4312 MkII retro speaker is firmly based. Of course, I
didn't know it well - we Brits seemed to be into the more polite
sounds from Quad, Spendor, KEF and B&W - but the C100 was the business
for the many US servicemen stationed in Europe, and examples 'trickled
down' from PX stores into the second-hand trade.
However much we might respect the neutrality and delicacy of our
Electrostatics and BC1s, when it came to throwing a party there was
only one winner and it rhymes with gerbil. The three-way driver
line-up, chunky cast frames and that dazzling Omo-white Aquaplas
12-inch bass driver cone are all about headroom and loudness, in an
era when voice coil adhesives made 'loud' unusual in hi-fi speakers.
Thirty years on the Quads need a rebuild, but I still use the BC1s
regularly, marvelling at theirunrivalled midband lucidity while taking
great care to respect those ancient voice-coils. Does the Century L100
also have a place in our modern world? Power handling isn't the issue
it once was, but variety is always welcome in our increasingly me-too
world.
You might even like the '70s styling, even the 'distinctive'
blue-painted baffle. The wide, shallow, squat shape was (and is)
intended for bookshelf mounting, so finding an appropriate stand will
not be easy. Then there are two knobs for adjusting relative mid and
treble volume - anathema to any self-respecting purist. The driver
layout looks problematic too because the graphics indicate setting the
speaker vertically, but that means having the mid and tweeter side by
side, which is likely to introduce phasiness.
The bass and mid drivers look like the originals, though the titanium
tweeter is of much more recent vintage. The room measurement confirms
its 'bookshelf' suitability, as close-to-wall siting gives the best
bass alignment. Elsewhere the balance (controls 'flat') looks rather
'forward' and very uneven through the presence region.
Sound Quality
The listening panels responded rather erratically to the 4312 MkII,
which actually makes sense as this is an erratic speaker. Where it's
good (ie in the bass and dynamics), it's very, very good - in fact,
quite the class act in this group test. Where it's bad (in the midband
coloration, imaging and phasiness), it can be pretty horrid.
That's too simplistic a synopsis, but the 4312 MkII is certainly an
uneven performer and so very different from today's speaker norms that
it's impossible to produce a meaningful 'blob chart' rating. How does
one weigh up the relative crudeness of the midband coloration against
the splendid dynamic tautness and punch, and the awesome headroom and
lack of strain when winding up the volume? If your tastes run to
choral, opera and other essentially acoustic music, approach this one
with caution. If rock is your main thing and the electric bass the
prime instrument, go check this out - you'll find it a whole lot of
fun.
Conclusion
Back in 1995 (HFC 143), I reviewed and Best Buy-rated a JBL L90 which
was also based on the L100, but only in outline. This 4312 MkII is
much closer to the original and significantly less expensive, but it
only gets a Recommended flag. That's because the L90 is the better
all-rounder, much less likely to offend our pre-millennial palates.
But this 4312 MkII is as close as you'll find to the original party
animal.

 Evitate di darmi brutte notizie o non c'è nessuno che li conosce???
Io non li conosco ma, "gugolando" velocemente, ho visto che qualche
informazione si trova:
