RL 940 / RL 940C

The RL 940 has been designed for both the professional user at small to medium-size audio, video and film studios and for the discerning music enthusiast. With the directivity index optimised for mid-distance monitoring, an excellent depth arrangement with neutral colouration is achieved. The coaxial configuration of the drive units delivers a sound stage with outstanding authenticity and consistency of imaging. The loudspeaker also distinguishes itself at high listening volumes through the presence of exceptionally low levels of non-linear distortion. The vented cabinet is tuned to 38 Hz and allows an uncompromising impulse response. The total system is additionally optimised for group delay.

The two channel amplifier with an electronic crossover is integrated within the rear of the enclosure and can be hinged out for maintenance purposes. An intermittent flashing LED indicates when the level reaches the system overload threshold. If the maximum level is exceeded continuously, the output level is attenuated by 20 dB to protect the components from damage. Two gapless variable low frequency controls provide separate adjustment of two frequency bands to enable the frequency response to be matched to the acoustic environment of the listening room.

In surround systems the RL 940 performs excellent as front and effect loudspeaker. As a centre speaker the RL 940C was designed, which is better integrable due to its lesser height. In addition the speaker is inclinable up to 15° to the top with the height-adjustable feet at the cabinet bottom. Therefore a perfect alignment to the listening position is possible. The centre speaker RL 940C doesn‘t fall behind the RL 940 regarding acoustical and technical performance. In connection with one of our BASIS models the surround system is perfectly complemented.

A variety of special stands and holding devices are available as accessories to the RL 940; appropriate mounting elements are integrated into the cabinet.
