The EVENT-121A is a direct radiating rear-loaded powered subwoofer system which incorporates a single 21″ neodymium loudspeaker providing “earth-moving” low-frequency reproduction for the EVENT Series line arrays. The combination of direct radiation and rear-loading provides a high output, tight and accurate sub-bass response.

The EVENT-121A employs the new DAS 21LFN loudspeaker which offers impressive features such as a 4″ sandwich split winding voice coil, a powerful FEA optimized neodymium magnet assembly and a FEA optimized suspension system with double silicon spider. The result is a loudspeaker with exceptional sensitivity, high power handling capacity and a quality suspension design capable of withstanding the stress and mechanical fatigue of today´s high-power pro audio systems. An aluminum demodulating ring benefits lower distortion and effective forced ventilation of the voice coil gap provides for a high thermal rating, and reduced power compression.

The EVENT-121A electronics package includes a 3200 Wpeak Class D amplifier and 24-bit high-end DSP for top quality audio reproduction. On the rear panel, controls can be found for gain, polarity and a continually variable low-pass filter which ranges from 63 Hz to 100 Hz. A unique “cardioid preset” button simplifies the use of subs in cardioid configurations, making setup of two to three units a snap without the need for an external DSP. The EVENT-121A is phase response coherent with the EVENT-208A, EVENT-210A and EVENT-212A active tops offering precise alignment. Two balanced inputs with stereo filtered outputs which can be sitched to pass-through connections are provided.
