About the S3900
The JBL Synthesis S3900 is a high-sensitivity, three-way floorstanding loudspeaker built for two-channel and home theater use. It uses two 10-inch woofers, a 1-3/4-inch compression driver for the mid/high range, and a 3/4-inch compression driver for ultrahigh frequencies, all paired with JBL's Bi-Radial horn system for wide dispersion and dynamic presentation. Manufacturer and retailer sources describe it as a studio-quality, horn-assisted design with rear ports, bi-wiring capability, and gold-plated terminals.
