At one point or another I think i’ve come across all of these things in various studios, offices, and edit rooms…  as I type this, I am listening to Tangerine Dream’s 1975 live LP ‘RICOCHET’ on a pair of JBL 18Ti, which were their hi-end home bookshelf speaker of the same era…  still sound great btw.

Below:  the 4350B.  And yeah it weighs 261 pounds.

Yard-Sale Speaker Spotter’s Guide: 1: JBL

JBLs ‘in-the-studio.’  Seriously tho you wouldn’t want to use these in an actual recording studio these days, trust me I’ve tried.

This week at PS dot com…  a collection of the better-sort of home hifi speakers that can turn up for $10 – $30 at yard sales in the local posh suburb.  Aside from some of the larger ‘marquee’ models, I think i’ve come across pretty much all of these at one point or another…  And remember, don’t be afraid of disintegrated foam surrounds on old woofers…  a $40 re-foam kit from Orange County Speaker and about 2 hours of your time is all it takes to bring most of these things back.  Scared me the first time too, but shit now I get to watch TV with a $1700 pair of Dahlquists that cost me all of $35.

Above, JBL Flair L45, Century L100, Decade L26, L88 Plus, Studio Master L200.

And last but not least… The L25 Prima!  JBL’s plastic-cased speakers circa 1974.  With optional coordinated record-bins.  This one’s for you MT.  You still got these things?

History

Cinema Sound Circa 1953

Today: some random bits+bobs of Sound-For-Film technology of the early 1950s.  Above: the All-New JBL Theatre Sound Systems, which claim to offer the higher-fidelity needed to properly reproduce the newly-available magnetic soundtracks that were being used in 35mm film at the time.  Prior to the introduction of magnetic 35mm film soundtracks in the 1950s, all film-sound was reproduced in theaters via an optical sound-track which ran alongside the edge of the film-frames.  Fidelity was limited, although I cannot say exactly to what frequency range.  Can anyone tell us what the first feature-film was to be exhibited nationwide with a magnetic soundtrack?

Above: Cinema Engineering presents… the fader!  Straight-line attenuators have certain advantages over rotary controls, such as quicker visual feedback and a range of motion that better correlates with human bio-mechanical consideration.  Nonetheless, rotary faders remained in use in pro audio well into the late 60s.  Does anyone know who first patented and/or marketed the linear fader?

Above: the Cinema Engineering 6517-E ‘Sound Effects Filter,’ aka a high-pass and a low-pass filter both built into a single instrument.   I could find this sort of thing very useful; especially for tracking multiple ‘stacked’ parts such as one singer delivering 7 vocal harmonies over a single phrase, as I found myself doing in a session earlier this week.  Just carve out all of the unnecessary super-high and super-low end… the 80 or 100 hz high-pass filter built into many mic preamps is certainly useful but it’s obvs not always the best cut off choice.

Above: an advert for Glen Glenn Motion Picture Sound Co. circa 1953.  Anyone out there work for this firm?  We’d love to hear yr stories….  drop us a line…

Above: RCA’s ‘film phonograph,’ an apparatus that records and plays-back 35 mm magnetic sound-tracks and plays-back 35mm optical sound tracks as well.  I ended up with a couple of 16mm sound track readers at Gold Coast Recorders; not sure what to do with them.  Has anyone had any luck converting an optical-track reader into a signal processing or signal generating device?  Seems like there’s some potential to make it into  interesting experimental instrument; strobe-light-controlled oscillator perhaps?
