The Dual CL 180 is a 3-way speaker system manufactured between 1971 and 1974 in Germany. It features a robust construction designed for high-performance audio output. The system incorporates a 245 mm cone woofer for low frequencies, a 37 mm soft dome midrange driver, and a 25 mm soft dome tweeter for high frequencies. The speaker cabinet is finished in walnut nature or a white sanding varnish, providing a classic aesthetic. With dimensions of 590 mm in height, 330 mm in width, and 220 mm in depth, the speaker is optimized for bookshelf placement. The unit weighs approximately 13.3 kg, indicating a solid build that contributes to sound quality. It has a recommended room size of 15 to 50 m² and features a nominal power handling of 50 W and a maximum of 70 W. The frequency response spans from 25 Hz to 25 kHz, ensuring a broad range of sound reproduction. The crossover frequencies are set at 800 Hz and 6,000 Hz with a slope of 12 dB/octave, facilitating effective separation of audio signals. The impedance is rated at 4 Ohms, which is common for such audio systems. The input terminal uses a DIN plug method for connectivity.
