JBL SR4726A
The JBL SR4726A is a professional two-way loudspeaker from the company's ScreenArray Series, a line JBL described as optimized for motion picture screen channels. It pairs a 15-inch 2206H woofer with a 2417H 1-inch exit compression driver, crossed over at 1.2 kHz. The cabinet is a straightforward rectangular design in 18 mm plywood with JBL's black DuraFlex finish, two Neutrik Speakon NL-4 connectors, and a tuned port arrangement using a pair of 100 mm ports.
The published specs are typical of a high-sensitivity cinema/main-PA box: 99 dB SPL sensitivity (1 W @ 1 m), 300 W continuous power handling (1200 W peak), and a maximum continuous output of 124 dB SPL. The frequency response is rated at 55 Hz–15 kHz within ±3 dB, extending to 38 Hz at the –10 dB points, with a 60° x 40° coverage pattern. It weighs 48 lbs and measures 27 x 18.5 x 18.5 inches. Suspension points (12 x M10, 10 x M8) were available as optional hardware, suggesting it was intended for flying as well as floor placement.
Beyond the manufacturer's product page, the documented record on the SR4726A is thin. Sound on Sound (UK, May 1996, p.199) ran an advertisement listing JBL professional products, though with no review content for this model. EQ Magazine (February 1997, p.100) noted the use of BSS Omnidrives for time alignment, crossover, parametric EQ, and gain control in a professional audio context. No production years, original price, or period review commentary have surfaced in the available research.
