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 todays 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 switched to pass-through connections are provided.
