Cello Series RR 212hl MK1
Compact Design, Massive Impact: Loudspeakers that Deliver
The Cello RR 212hl MK1 is a compact, horn-loaded 3-way passive bi-amped loudspeaker designed for exceptional clarity, efficiency, and directivity control. Its LF section features dual custom 12" drivers with V-chamber reflex-tuning for added sensitivity and low-frequency focus. The HMF section, built around an 8" driver and 1" HF coaxially horn-loaded, delivers smooth crossover, reduced distortion, and high output, making it ideal for both touring and installation.
Available in three dispersion variants—40°x40°, 40°x60°, and 40°x90°—the RR 212hl MK1 offers unmatched rigging flexibility. It can be deployed as a single cabinet or in arrays (up to 3 wide or 3 deep), combining long-throw and near-field coverage with ease. Its acoustical horn design enhances sensitivity and mid-band SPL, ensuring brilliant performance even in reverberant spaces.
The RR 212hl MK1 delivers premium dynamic performance with up to 10 dB lower distortion (1–3 kHz) compared to conventional systems. Optimized with the CSC Maestro MS 26 controller and compatible with CSC subwoofers (CR 218s, RR 218s, RRH 218s, RRI 21s), it provides seamless system integration and powerful, distortion-free sound.
