At its foundation, the JBL S4700 uses an all-new cast-frame 15-inch woofer (2216Nd) with a powerful dual 3-inch voice coil and neodymium motor structure for outstanding balance with the horn-loaded compression drivers.
Mid- and high-frequencies are reproduced by a pair of titanium diaphragm compression drivers and a single-piece, SonoGlass® dual horn assembly. The 2-inch Aqua-Plas™-coated titanium diaphragm compression driver (175Nd-3) is mated to a 90° x 60° Bi-Radial® horn and delivers mid- and high-frequencies with lifelike dynamics and startling realism while an ultra-high frequency 0.75-inch titanium diaphragm compression driver (138Nd) with a 60° x 30° Bi-Radial horn recreates critical air and spaciousness. JBL says that the driver’s response extends to beyond 40kHz and all three of the S4700's drivers are matched to deliver a smooth tonal balance across the entire frequency spectrum. It also has a bass reflex enclosure with a rear-firing tuned port.
Premium-quality network components and dual binding post inputs ensure audiophile performance in any application.
The attractive furniture-grade cherry wood veneer enclosure is internally braced at critical points and is tuned via a rear-firing port.
The S4700 is intended for use in high-performance 2-channel audio systems or as an LCR loudspeaker in a JBL Synthesis multi-channel home theater installation.
