The Chrono series is available in black or white, each in a combination and matte vinyl decor and "matte" varnish. Robust and neutral fabric slip-on covers cover the baffle if desired. A practical highlight are the Rear-Fix cover holders on the back of the speakers. The speakers of the Chrono series are equipped with a single-wiring connection terminal. The silver-plated screw terminals accept cables with cross sections of up to 10 mm, offer the highest degree of conductivity and guarantee long-term stable contact.
