3 System description
The RL 903K is a main studio control room monitor with cardioid radiation characteristic from 35 Hz
through 100 Hz for universal application. Main operational areas are audio, video and motion picture
studios. By the cardioid characteristic those reflections caused by the wall behind the speakers are
minimized. To enhance the low-frequency range we combined the coaxial arranged high- and mid-
frequency driver unit with a powerful long-throw bass driver unit. Its coaxial arranged transducers
ensure a sound impression with a high degree of homogeneity to a point source. We spend much
effort in developing constructive ways to ensure a low degree of non-linear distortion. To keep
short-term reflections small and achieve a high fidelity of sound we used a special arrangement for
the high- and mid-frequency drivers and also designed the front side of the speaker asymmetrical.
Although the cabinets dimensions a very compact, the system obtains a low-frequency cut-off at
35 Hz.
The 3-way MOSFET-amplifier with active crossover is integrated into the back of the cabinet and is
hinged for service purposes. An intermittent LED indicates sound pressure levels within the overload
margin of 3 dB and warns of clipping. Beyond this limit the output level of the high- and mid-
frequency drivers get damped by 20 dB to protect the speaker’s components.
Optionally, the coaxial arranged high- and mid-frequency driver unit can be supplied revolved
by 90 degrees, that way the speaker can be installed either in vertical or horizontal position. To
compensate their placement the speaker features two controllers to continuously adjust the low-
frequency response.
A variety of special stands and racks is available as accessories. According fixing elements have been
integrated into the loudspeaker cabinet.
