The Kenwood LS-405 is a compact speaker model manufactured by Kenwood in Japan between 1976 and 1977. It features a classic wood finish in American walnut, showcasing a refined aesthetic that complements various decors. The unit is structured as a 2-way bass-reflex loudspeaker system, equipped with a low-frequency 250 mm cone driver and a 25 mm dome tweeter for a balanced audio output. Designed to handle power nominally at 30 watts and up to 50 watts in music, it operates at an impedance of 8 Ohms. The efficiency rating of the LS-405 is tailored for clear sound delivery, with a frequency response spanning from 58 Hz to 20 kHz. The crossover frequency is set at 2,000 Hz, allowing for effective separation of audio signals between the woofer and tweeter. With dimensions of 325 mm in width, 590 mm in height, and 280 mm in depth, the speaker weighs approximately 14 kg, making it substantial yet manageable. The original retail price was around 120 US dollars or 390 Deutsche Mark, establishing it as a mid-range option for audio enthusiasts during its production period.
