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 & sophisticated loudspeakers in the world today. At its foundation the S4700 uses an all-new cast-frame 15-inch woofer (2216 Nd) with a powerful dual 3-inch voice coil & neodymium motor structure for outstanding balance with the horn-loaded compression drivers. Mid- & high-frequencies are reproduced by a pair of titanium diaphragm compression drivers & a single-piece Sono Glass® dual horn assembly. The 2-inch Aqua-Plas™-coated titanium diaphragm compression driver (175 Nd-3) is mated to a 90° x 60° Bi-Radial® horn & delivers mid- & high-frequencies with lifelike dynamics & startling realism while an ultra-high frequency 0.75-inch titanium diaphragm compression driver (138 Nd) with a 60° x 30° Bi-Radial horn recreates critical air & spaciousness. Premium-quality network components & dual binding post inputs ensure audiophile performance in any application. The attractive furniture-grade cherry wood veneer enclosure is internally braced at critical points & 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 theatre installation.
