RL 904 Studio Reference Monitor Loudspeaker
Max SPL @ 1m: 106 dB
Bandwidth: 40 Hz - 20 kHz ±3 dB
Size (H x W x D): 398 x 254 x 345 mm
Weight: 16 kg
Active two-way bass-reflex monitor with a coaxial mounted 25mm dome high-frequency driver unit exhibiting excellent group delay performance. 2 way MOSFET amplifier with active crossover. LED overload indicator and electronic protection of the drivers against damage from overload. Two continuously variable controls provide low frequency compensation for speaker placement.
Power dispersion optimised for mid-field monitoring in medium or smaller sized music, video and film production studios.
The coaxial driver system can be rotated through 90 degrees making the RL 902 suitable for either vertical or horizontal mounting:
Studio Reference Monitor Loudspeaker RL 906
Max SPL @ 1m: 104 dB
Bandwidth: 50 Hz - 20 kHz ±3 dB
Size (H x W x D): 255 x 180 x 200 mm
Weight: 5.5 kg
The most compact studio monitor in the RL series. Active two-way bass-reflex monitor with a coaxial mounted 25mm dome high-frequency driver unit exhibiting excellent group delay performance. The power directivity characteristics allow bulkhead installation without the need to angle inwards for good imaging. 2 separate MOSFET amplifiers with active crossover. LED overload indicator and electronic protection of the drivers against damage from overload. Three continuously variable controls provide frequency/level compensation to correct for loudspeaker placement.
A Near-field monitor ideally suited to music and video production, OB vans and multi-channel work.
High tonal compatibility within the RL-family makes the RL 906 the ideal partner for near-field use in conjunction with larger speakers in the range.
Active Studio Monitor MO-1
Max SPL @ 1m: 102 dB
Bandwidth: 100 Hz - 20 kHz ±3 dB
Size (H x W x D): 198 x 146 x 160 mm
Weight: 3.2 kg
Two-way coaxial active loudspeaker system was developed for near field monitoring with low listening fatigue. Powered by two-separate amplifiers mounted in the rear of the enclosure and an active crossover. The level control, bass roll-off control, and the overload display are located on the front panel. A near-field monitor ideally suited to smaller OB vans, multi-channel surround or loudspeakers for small rooms and for conference sound requirements.
Active Studio Monitor MO-2
Max SPL @ 1m: 108 dB
Bandwidth: 46 Hz - 20 kHz ±3 dB
Size (H x W x D): 398 x 254 x 245 mm
Weight: 11 kg
Two-way coaxial active loudspeaker system, developed for near field monitoring with low listening fatigue. Powered by two-separate MOSFET amplifiers mounted in the rear of the enclosure. Controls are provided to adjust high and low frequencies and in the region of 300 Hz to compensate for room positioning.
A mid-field and near-field monitor designed for small and medium sized music and video production studios, or in OB vans.
With characteristics well-matched to the RL-family, the MO-2 is ideally suited to separate location recording and mixing by maintaining high tonal compatibility with the larger speakers in the range.
2-Way Active Studio Reference Monitors with descrete concentic drive units to maintain acoustic decoupling and eliminating waveguiding
