RL 930K

The RL 930K has been designed for both the professional user at medium-size to large audio, video and film studios and for the discerning music enthusiast. The directivity index has been optimised to listening distances between 2.5 and 5 metres. Low and middle frequencies are reproduced by a specially designed 10-inch cone loudspeaker. In the treble range, the RL930K uses three vertically arranged 1-inch tweeter calottes that are positioned coaxially in front of the woofer/midrange system. The RL930K, a two-way studio monitor, features our K Technology (cardioid radiation characteristics in the bass range), which has proven reliable since many years. This technology makes it easy to position this loudspeaker, even with respect to bass difficulties, and it considerably reduces distracting rearward-directed room reflections. Thanks to the powerful integrated analogue amplifiers and the high system sensitiveness, this loudspeaker combines the flawless homogeneity of a two-way system with a dynamic range that is otherwise limited to mostly larger three-way designs. The result is that non-linear distortions stay extremely low even at high reproducing levels. Moreover, the loudspeaker features group-delay-time optimisation. Summing up all the constructive measures, the RL930K achieves the seamless sound compatibility with all other products made in the our manufacture. The highly neutral tone quality, excellent spatial performance and depth arrangement, together with fatigue-free monitoring of even most complex sound events are typical ME Geithain characteristics of this loudspeaker.

The power amplifier module with electronic crossover is integrated into the rear wall of the cabinet and can be swung out for maintenance purposes. An intermittent LED signalises overmodulation. If the maximum level is exceeded, the output level will be attenuated by 20 dB in order to protect the components from overloading. For adapting the frequency response to the acoustic characteristics of the reproduction room, a low-frequency room compensation can be achieved within two continuously variable frequency bands.

A variety of special stands and racks is available as accessories. According fixing elements have been integrated into the loudspeaker cabinet.

Important information about deviations from sample pattern

Wood is a natural product. Even the most thorough manufacturing can result in deviations in colour or structure and is no cause for complaint.
Images are represented differently on every screen and hence not colour-proof.
