LD Systems MON121AG2 - 12 Inch Active Stage Monitor

Manufacturer: LD Systems

Item #: LDS-MON121AG2   •   MFG #: MON121AG2




The specially developed 12" coaxial speaker with an integral 1" HF driver and powerful ferrite magnets stands out because of a precisely symmetrical dispersion over 75° x 75° and attains a maximum sound-level pressure of 124dB with maximum resistance to feedback. It is driven by a Class AB power amplifier with a power output of 1000W Peak. The frequency response curve is 80Hz - 20kHz. Dependable operation of the LD MON121AG2 is ensured by a limiter that prevents overloading of the speaker and a protection circuit that guards against short-circuiting.
