Cello Series RR 212hl
Compact Design, Massive Impact: Loudspeakers that Deliver
The Cello RR series is a horn-loaded loudspeaker system that is relatively light and compact, offering excellent clarity and directivity control. Cello RR 212hl is a passive bi-amp driven, 3-way horn-loaded, point source loudspeaker. The LF section features two customized 12" drivers loaded using a V-chamber aided reflex-tuning for added sensitivity and low-frequency directivity. The horn supporting the 1" HF in the HMF section acts as a phase plug, increasing the sensitivity and directivity of the mid and high sections. The 8" driver seamlessly crosses over into the 1" HF using a passive network, making each driver highly efficient and distortion-free by reducing their stress. The HMF section being coaxially horn-loaded gives a great solution for both installed and touring sound applications. Its cleverly designed horn acts as an acoustical amplifier, enhancing its sensitivity and directivity. This increases the mid-band SPL, propagating the highest frequencies without compromising power. This design helps the cabinet to perform brilliantly in reverberant environments. The CSC RR 212HL has three variants having different dispersions (VxH).
