About the JSR

The Sotto Voce JSR is a 3-way closed-box active loudspeaker designed around a 165 mm coaxial mid/high driver with a neodymium magnet, delivering coherent sound dispersion over seven octaves. It includes two 200 mm long-stroke fiberglass cone bass drivers mounted back-to-back to cancel cabinet vibrations and optimize bass response in real listening rooms. The loudspeaker features 400 W of internal class D amplification, providing dynamic, distortion-free sound at any volume while maintaining low energy consumption. Its moderate width of 195 mm allows it to deliver full-range sound without external amplifiers. It supports balanced analog or digital audio inputs for direct connection to high-quality streamers, DACs, or preamps, minimizing system complexity. The loudspeakers are handcrafted and available in white solid surface finishing (Krion® Snow White) or custom colors with matte or high gloss finishes. Each unit is shipped in a reusable custom aluminum flight case for secure transport.
