JBL Synthesis S4700

The S4700 is a floorstanding 3-way high-performance loudspeaker built upon the same professional-grade technology used in the acclaimed Project K2 S9900, one of the most advanced and sophisticated loudspeakers in the world today.

At its foundation, the 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.

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.
