[. . . ] After successfully scaling our equivalent of that formidable mountain, we understand a little more about the complex matrix of motivations and emotions that drives the adventurer. Our K2 was the creation of a loudspeaker that would bring the unique JBL Professional listening experience to the home in an uncompromising form. And with the innovative Project K2 S9800, JBL engineers created a reference loudspeaker system for the 21st century. Now the all-new K2 S9800 Special Edition scales even greater heights. Effortlessly delivering the full bandwidth and dynamics of even the most demanding sources ­ without suppression at any listening level ­ Project K2 loudspeakers offer a sense of realism and sonic accuracy that will transport you to the concert hall. [. . . ] The K2 S5800 380mm (15") (1500FE) and S4800 300mm (12") (1200FE) bass drivers are designed for large excursion and power linearity with ferrite magnets and JBL's new SFG magnetic circuit. 9 tem applies DC bias to the capacitor, eliminat- THE MUSIC, REVEALED 1940's NYLON STOCKINGS, FILM NOIR, THE DAWN OF AUDIO.

TODAY WITH PROJECT ARRAY, JBL introduces the legendary 4320. With a high-frequency compression driver and acoustic lens in a four-way configuration, it becomes the definitive studio monitor of the Space Age. And JBL becomes standard equipment at major rock concerts. Remember that little gathering at Woodstock?While bass and midrange frequencies can survive some interaction with walls and furniture, high and ultrahigh frequencies are greatly diminished by it, especially at high listening levels. The high and drive a 75mm (3") Aquaplas-treated aluminum dome mounted in a rigid, constant-directivity horn. This is the secret behind the threedimensional imaging of JBL Project Array. Titanium super tweeter The edge-wound voice coil attached directly to a 25mm (1") titanium diaphragm and driven by a 50mm (2") neodymium motor assembly delivers uniform response out to 40kHz. The vertical SonoGlass constant directivity horn maintains an optimum dispersion pattern of 60 degrees x 30 degrees. Classic JBL bass drivers The Project Array woofers are all based on acclaimed JBL Professional bass drivers. They employ massive ferrite motor assemblies, edge-wound copper voice coils and durable rubber surrounds to drive an essentially inert Aquaplas-coated pulp-cone assembly. Built to play loud and long, they proudly reflect their professional heritage. ultrahigh crossover sections are isolated on a separate board in a different section of the enclosure to minimize crosstalk with the low-frequency crossover. 100 90 80 70 60 50 30 100 1k Hz 10k 20k 50k HF LF UHF 38mm (1-1/2") copper edge-wound voice coils, the 045Ti 25mm (1") pure-titanium compression driver and the 435AL 75mm (3") Aquaplastreated aluminum-dome compression driver.

It incorporates a powerful W1500H 380mm (15") bass driver with 100mm (4") copper edgewound voice coil and a dedicated 1000-watt Class D digital power amplifier mounted in a trapezoidal enclosure. 17 ARRAY SPECIFICATI P R O J E C T A R R AY 15 0 0 · 14 0 0 · 10 0 0 · 8 8 0 Description Frequency Response Power Handling Sensitivity (1W @ 1m) Nominal Impedance 1400 Array 3-Way, 350mm (14") Floorstanding Speaker 32Hz ­ 40kHz 300 Watts 89dB 8 Ohms 1000 Array 3-Way, 250mm (10") Floorstanding Speaker 35Hz ­ 40kHz 200 Watts 89dB 8 Ohms 800 Array 3-Way, 200mm (8") Bookshelf Speaker 55Hz ­ 40kHz 200 Watts 88dB 8 Ohms 880 Array 3-Way, Dual 200mm (8") Center Speaker 70Hz ­ 40kHz 200 Watts 90dB 8 Ohms 1500 Array 375mm (15") 1000W Front-Firing Sub 25Hz ­ 400Hz, variable N/A N/A N/A 18 · 80 0 ONS A Message From Greg Timbers, JBL's Chief Systems Engineer I've long been a fan of compression-driver systems. They have a speed and effortlessness unmatched by direct-radiator systems. Current hardware is very low in distortion, has smooth frequency response and can be designed to have very smooth, consistent directivity patterns. [. . . ] The LF enclosure needed to be heavy, solid and vibration free. In addition, it needed to allow the horn module to sit as low as possible to reduce the center-to-center distance between the LF and HF drivers. The horn itself is molded from a high-density resin material using an extremely thick wall section. This makes the horn heavy and acoustically inert. [. . . ]
