Redline 140

About the Redline 140

The Bang & Olufsen Redline 140, also known as Beovox RL 140, was introduced in 1986 and produced until the early 1990s. It is the largest model in the RL range of passive loudspeakers, designed with a unique concave cabinet that reduces resonance and allows flexible placement (floor, wall, ceiling). The speaker features a bass reflex design with two 165mm (6½") woofers, a 125mm mid-range unit, and a 25mm (1") tweeter, delivering a frequency range of 40 to 20,000 Hz. It can handle a maximum noise power of 140 watts and long-term input power of 200 watts, with an impedance of 8 ohms and sensitivity of 93 dB at 1 watt. The crossover frequencies are 800 Hz and 3000 Hz. The cabinet volume is 38 liters, and the speaker weighs approximately 15 kg. It was originally designed to be driven by powerful amplifiers like the Beomaster 8000 or Beolab 150. The Redline 140 was replaced by the Beovox RL 7000 in 1992. The speaker is noted for its excellent sound staging, neutrality, and flexibility in placement, with an optional floor stand and adjustable angle for optimal listening position. The distinctive red line around the cabinet edge gives the series its name, with some later versions featuring a silver line on white cabinets.
