Desono ENT212 – Powerful All-Weather Column Line Array with Precision Coverage
The Desono™ ENT212 is the largest and most powerful member of the ENT200 series—expertly engineered to deliver focused sound, wide coverage, and exceptional intelligibility in acoustically challenging environments. With its weather-resistant design, advanced internal crossover, and high output capability, the ENT212 is the ideal solution for medium-sized venues where speech clarity and musical detail must cut through noise and reverberation.
Housed in a heavy-duty extruded PVC enclosure, the ENT212 features twelve 80 mm LF drivers and four Compact Ribbon Emulator (CRE) HF tweeter arrays, arranged in a 4-way frequency-shaded configuration for precise vertical control. This setup extends low-frequency directional performance far beyond what smaller column speakers can achieve.
Ideal for gymnasiums, school auditoriums, churches, corporate AV, music clubs, and even stadiums (when paired with subwoofers), the ENT212 is a full-range solution that delivers professional-grade fidelity and speech intelligibility—even in the most reverberant spaces.
