The RL 140 is a directional speaker with minimum lateral sound radiation. It has been developed for the targeted acoustic irradiation of confined listening areas or to separate several sound sources from one another in the same room.

In addition to directivity across the entire frequency range, the RL 140 offers pleasant sound characteristics and good efficiency levels. The RL 140 is either suspended above the listening zone or directed towards it on a ball joint bracket. For optimum results, the distance between the speaker and listener should be as short as possible.
