RL 904

The RL 904 is an all purpose main loudspeaker for middle size or smaller audio-, video- and film production studios. Its coaxial arranged transducers ensure a sound impression with a high degree of homogeneity to a point source. The power concentration is designed for middle distance monitoring situation, at which a great differentiation in depth and a high fidelity of sound is guaranteed. Non-linear distortion remains small even at high sound pressure levels. The bass reflex system obtains a low-frequency cut-off at 40 Hz and provides a high degree of sound accuracy. We designed the whole system to achieve an optimum group delay.

The two-way MOSFET-amplifier with active crossover is situated at the back of the cabinet and is easily accessible for maintenance. An intermittent LED indicates sound pressure levels within the overload margin of 3 dB and warns of clipping. Beyond this limit the output level gets damped by 20 dB to protect the speaker’s components. To compensate their placement the speaker features two controllers to continuously adjust the low-frequency response.

There are various stands available as optional extras, which fit in the integrated appliance.
