my name is Mark Gander I'm the director of JBL technology here at JBL professional division of Harman and what I'd wanted to take the time to do today is to go through a little bit of history but try to show you how that history sets the tone for what we do at JBL and in fact JBL does in fact stand for somebody's named James B Lancet he's the founder of the company he actually was doing radio speakers in the 1920s followed through from those radio speakers when the industry was called upon to make the movies talk and it the requirement was there to reproduce sound for large audiences hundreds and thousands of people in large movie theaters in fact the system that Lansing worked on became the first industry standard a cinema loudspeaker system this is a small version of it a high-frequency multi-cellular horn crossed over to a folded horn with woofers in it for the low frequencies so from that system Lansing created a very small system for the production rooms a small multicellular horn a single 15 inch woofer and a small vented direct radiator box and this system was developed in the 1930s and was called the iconic system and essentially this is the first studio monitor here you can see in the early days of for track recording they would actually have four monitors one for each of the four tracks above the window looking into the recording room and the engineer at the console this is how it was done in the 1960s we also then developed the first bookshelf monitor this is a 3-way 12-inch direct radiator type system the 12 inch woofer five inch mid-range a one and a quarter inch tweeter and that became the first standard of the industry for the the console top monitoring here's an example of that system and you can see the white phone JBL was actually the first to use the white damping material to make a laminated cone to make a very neutral and low distortion woofer and in fact that was such a successful speaker that JBL made a consumer version of it same exact parts but in a walnut box with a very distinctive pancake grille design and it was called the L 100 which was a very very popular - LD speaker through the 1970s JBL was the creator of multi way monitors not just two ways but three ways and even four way studio monitors this was in fact the largest of the 1970s 4300 series it was called the 4352 15 inch woofers a 12-inch lower mid-range a very large compression driver with one of those acoustic lenses and ultra high-frequency slobbering radiator tweeter people like Frank Zappa and Pete Townsend of the who would use four of these experimenting with quad during the nineteen seventies when we move from the 70s into the 1980s JBL created the by radial studio monitors we created a technology called by radial horns that sweeps a radial arc in both the vertical and horizontal directions and gives a very very consistent response but Lansing himself one of the first products created by the early Lansing company in the late 1940s was a 15 inch woofer called a D 130 and Lansing used very innovative techniques at the time the most advanced magnet material that alnico aluminum nickel and cobalt that was developed during world war ii doing things like cast pot structures with a magnet is within behind here that the voice coil diameter was four inch no one had ever used a very large four inch diameter voice coil before using edged round aluminum wire on the voice coil using past frames the curvilinear cone the the aluminum center don't extend the high frequencies all these were brought together by using new materials and new technologies for instance one of the claims to fame is Leo fender adopting this and other similar speakers as the premium step up for Fender guitars starting in the late nineties actually in the 1960s JBL created amplifiers that mounted in the loudspeaker enclosures and they were the they were essentially the first powered systems both for studio monitors and for sound reinforcement in 1960 JBL was the first to adapt titanium finding out that Lockheed and other major aerospace companies could form titanium into a thin foil and have it be formed into diaphragms here's a an example of one of our titanium diaphragms and that's been titanium foil formed it just like some of the preceding aluminum foils were formed we also have patents on the ribbing pattern on the dome on these diamond shapes on this what we call the surround on the edge that allows the the motion of the diaphragm and in the lab we have a number of different displays of starting with some of the classic JBL products from JBL's history the first being the d1 30 this is the 15-inch full range loudspeaker that Lansing developed when he first started the JBL company in 1946 next to it here is a cutaway version of the d1 40 very similar using the same pot structure which we call it the rear magnet assembly the central Alma Coe magnet you can see the voice coil in the magnetic gap this is the 4320 studio monitor plastic two-way allowed speaker 15 inch woofer an acoustic lens these plates and this precisely mathematically derived cut in the middle allows the high frequencies to disperse in a consistent horizontal pattern and right next to it is the original studio monitor the first studio monitor from the 1930s the Lansing iconic next to it is a Cabot the cabaret series which was the first developed in the late 1970s and all through the 1980s along the way here is another kind of acoustic lens we talked talked and showed the slant plate lenses this is actually a perforated plate lens a circular or conical sound coverage pattern and this was used in the 1954 cinema systems as the high frequency to disperse the sound across the whole audience and finally in our history section the classic JBL 3-way 12-inch studio monitor the 4310 the white cone is still a very large voice coil in this case of 3-inch diameter voice coil with a non-lethal magnet a 3-way system a five inch cone mid range and a wonderful quarter inch cone high frequency tweeter lots of artists rely on JBL just a few of them are Jimmy Douglas Frank Philip Eddie works with Paul Simon and a host of artists making konchol Paulson Weiss who's the mixer for the Emmy Awards for the Grammy Awards eddie kramer grammy award-winning engineer for jimi hendrix of the old days along with Led Zeppelin and doing modern applications as well JBL has been awarded with many prestigious honors over the years JBL was awarded a technical Grammy Award in 2005 by Narus the National Academy of Recording Arts and Sciences the grammy organization and JBL overall every year subsequently has been awarded over fifteen of the prestigious tech awards technical excellence and trade to creativity awards for both Sarah reinforcement loudspeakers and studio monitor loudspeakers there create and present the highest fidelity in sound reproduction and reprinted in this section of the JBL professional lobby we have our awards but first number of of our friends over the years have signed loudspeakers there's the Les Paul wishing us a 60th anniversary in 2006 Phil Ramone the famous recording engineer and producer doing the same this one's signed by BB king a classic p120 guitar speaker a 12-inch version of the D 130 and all the members of the who've signed one of our LS are 63 25p studio monitors also the plaques in the back this is a thank-you from the Motion Picture Academy the Osprey organization and one from the television Academy for our services and sound systems at their reference theaters and also a gym level from Apollo 13 he was a speaker at one of our meetings but down the way you can see three cases with our more than 15 tech awards technical excellence and creativity awards for specific products as well as many other awards in both the tour sound industry the studio industry and all aspects of loudspeaker used by the key to JBL if you characterize what really makes up JBL it's this this the striving for sonic performance through the use of technology and innovation in design quality and reliability in delivering those products and the company stability and the longevity that we have done that for many many years and plan to continue well into the future you
