D.A.S. Audio Event-121A Description

The D.A.S. Audio Event-121A is designed to provide professional-grade bass reinforcement for live events and installations. Powered by a 3200W peak Class-D amplifier, this subwoofer drives a 21-inch DAS 21LFN woofer, delivering low-end frequencies from 30 Hz to 125 Hz with a peak SPL of 141 dB. Its direct-radiating, rear-loaded design ensures accurate bass reproduction, making it perfect for medium to large venues. The integrated DSP, accessible through the DAScontrol™ interface, allows for precise adjustment of low-pass filter settings (63 to 100 Hz), level control, and polarity. The cardioid switch is particularly useful when deploying multiple subwoofers, reducing unwanted low-frequency energy behind the system. With two XLR inputs and loop-thru outputs, the Event-121A easily integrates into larger audio setups. Its robust birch plywood enclosure, coated in ISO-flex paint, is designed for durability, while built-in handles and wheels make transportation easy.
