Very nice Bang & Olufsen set - Redline RL 45.2 Speakers. These speakers are in excellent condition just some scratches under od back side which are not visible during normal use . The cloths look great, and even the plastic strips, which are often missing, are on it. The sound is as you may expect from Bang & Olufsen. These speakers can be connected to all amplifiers. So also not B&O. Real eye-catchers. Manufactured: 1988 - 1992 Designer: David Lewis Colours: grey The idea behind BeoVox Red Line speakers was one of flexibility. A Red Line speaker was so flexible, that this could be placed anywhere. On the ceiling, the wall, or on the floor. You could semi-permanently hang them on the wall, and if you had a party, you could place them on the ground to put emphasis on the bass. The different ways to place them accentuate different frequencies. You can also tilt them if you hang them on the wall. With this, you can customise the sound and precisely aim the sound at your listening position. Red Line however was more than just flexible. It was an impressive bass reflex speaker with a revolutionary cabinet which was bent ‘around the sound’ and therefore eliminated annoying resonance because there were no parallel surfaces.
