The JBL Industrial Series Model 8330 loudspeaker system offers sound contractors and audio system designers a professional quality alternative to conven- tional “foreground music” speakers. Its wideband response and high reliability make it ideal for use as a theatre surround, and in retail establishments, restaurants, lounges and other commercial applications.
The three-way system features a 200 mm (8 in) low fre- quency driver for smooth, extended bass response, a 130 mm (5 in) midrange transducer for the critical midrange frequencies, and a 25 mm (2 in) titanium-laminate dome tweeter to provide broad, even coverage of the high fre- quencies. A dual-purpose, switchable crossover network makes the Model 8330 ideal for both cinema surround and commercial foreground music installations such as restaurants, retail establishments, and lounges. The special tight-cluster arrangement of the transducers, in conjunc- tion with the crossover network design, provides uniform polar response in both the horizontal and vertical planes. The enclosure is constructed of dense stock in a unique cabinet shape which reduces internal resonances while providing a U-degree down aiming angle for the trans- ducers. The location of the crossover network on the top panel permits easy access to the network switch and input terminals, subsequent to speaker mounting. Six internal “T” nuts allow quick attachment of Omnimount or other mounting hardware without opening the cabinet. Enclo- sure finish is satin black vinyl, with a dark grey grille.
The Model 8330 offers many of the same design features found in JBL’s prestigious line of studio monitors. The crossover network has bypass capacitors wired in parallel with the larger active capacitor values in the circuit to reduce hysteresis effects on the signal. This provides improved resolution of complex transient waveforms. The woofer and midrange cones utilize a laminated high poly- mer composite which provides a combination of optimum stiffness, mass, and internal damping to ensure that the cone behaves more like a true piston. The tweeter dome is laminated with vapor deposited titanium in order to obtain both the structural integrity of a “hard” dome and the damping characteristics of a traditional soft dome. A unique acoustic “contact lens” is an integral part of the tweeter design, and provides flatter high-frequency response by shadowing the center section of the dome.
Built to traditional JBL standards of quality and preci- sion, the loudspeakers are subjected to stringent tests to ensure that the materials and adhesives will stand up to long-term use under adverse conditions.
Architectural Specifications:
The loudspeaker system shall consist of a 203 mm (8 in) low fre- quency loudspeaker, 130 mm (5 in) midrange loudspeaker, 25 mm (1 in) dome high frequency driver, and frequency dividing network installed in a ported enclosure. The frame of the low frequency and midrange transducers shall be manufactured of stamped steel, and their magnetic assembly shall utilize a ferrite magnet. The low fre- quency voice coil shall be 38 mm (1% in) in diameter and shall be made of round-wound copper.
The frequency dividing network shall have crossover frequencies of 650 Hz and 3.1 kHz and shall be of the parallel L-C type. Polypro- pylene and/or polystyrene bypass capacitors shall be wired in parallel with the network’s larger non-polarized electrolytic capacitors to reduce the hysteresis effects on the signal. The frequency dividing net- work shall be equipped with a two-position switch to allow selection of two high-frequency response curves. One curve shall be consistent with the IS0 2969 Curve X specification and the other curve shall cor- respond to the nominal system design (flat) response.
Performance specifications of a typical production unit shall be as follows: Measured sensitivity (SPL at 1 m (3.3 ft) on axis with 2.83 volts input, swept 500 Hz-Z.5 kHz) shall be at least 91 dB SPL. Usable fre- quency range shall extend from 40 Hz to 20 kHz. On-axis response, measured at a distance of 2 m (6.6 ft) or more under free-field condi- tions shall be ± 3 dB from 70 Hz to 14 kHz. Nominal impedance shall be 8 ohms, Rated power capacity shall be at least 100 watts continuous pink noise, based on test signal of filtered random noise conforming to international standard IEC 268-5 two hours duration.
The enclosure shall be solidly constructed of 3⁄4 inch stock with all joints tightly fitted and glued. Overall dimensions shall be no greater than 494 mm (197/16 in) high by 481 mm (1815/16 in) wide by 257 mm (101/8 in) deep. Finish shall be black vinyl with dark grey fabric grille. Six T-nuts and bolts shall be provided, one on each side panel and four on the rear panel for attaching Omnimount or other mounting hardware.
The system shall be JBL Industrial Series Model 8330.
