The Technics SB-C600-K is a 2‑way bookshelf speaker system with a coaxial driver. Each enclosure uses a 6-inch cone woofer and a 1-inch dome tweeter in a single coaxial unit, held by Balanced Driver Mounting Architecture to suppress cabinet vibrations. It delivers a 40 Hz–100 kHz overall frequency range into a 4 Ω load, with IEC input power of 60 W (max 120 W). Recommended amplifier range is 40–120 W per channel.
