D.A.S. Audio Event-121A Powered 21" Direct Radiating Rear-Loaded Subwoofer System

The D.A.S. Event-121A is a powered, 21" direct-radiating, rear-loaded subwoofer system designed to provide extended bass response to the Event line array series full-range cabinets, and it is well suited for rental houses, bars, clubs, mobile DJs, or any pro audio application. The Event-121A utilizes a 3200W Class-D amplifier to power the 21" woofer, provinding a frequency response of 32 to 125 Hz with a peak SPL output of 141 dB.

The birch plywood enclosure is finished with black ISO-flex paint and includes two handles (one per side) and a third on the rear top as well as two wheels for ease in transport. The rear panel offers two XLR inputs, two XLR loop-thru outputs, a level control, a 63 to 100 Hz low-pass filter control, and a dedicated polarity switch. When using two or three subwoofers, a cardioid switch is included to help reduce the bass response at the rear of the stacks, cutting down on stage volume and feedback issues. The top panel offers a pole-mount socket for use with 35mm speaker poles for mounting full-range speakers. Additionally, the D.A.S. Event-121A features a powerCon input and pass-thru to daisy-chain power to multiple subwoofers and ships with a power cable.
