DAS Audio Event 121A - 3200W 21-inch Powered Rear Loaded Subwoofer with Birch Plywood Enclosure in Black Finish

The DAS Audio Event 121A is a powerful 3200W, 21-inch powered rear-loaded subwoofer that is expertly designed to deliver "earth-moving" low-frequency reproduction for the EVENT Series line arrays. This subwoofer employs a direct radiating rear-loading configuration, allowing it to achieve high output and provide tight, accurate sub-bass response, making it an ideal choice for live sound applications, festivals, and large venues.

At the heart of the Event 121A is the newly engineered DAS 21LFN neodymium loudspeaker, which features a robust 4-inch sandwich split winding voice coil. This advanced design allows for exceptional sensitivity and a high power handling capacity. The speaker's FEA (Finite Element Analysis) optimized neodymium magnet assembly and suspension system - equipped with double silicon spiders - enable the 21LFN to withstand the mechanical stresses and fatigue often experienced in high-power pro audio environments. Additionally, the inclusion of an aluminum demodulating ring reduces distortion, while effective forced ventilation of the voice coil gap enhances thermal management, ensuring reliable performance even during demanding use.

Driving the Event 121A is a high-efficiency Class D amplifier that delivers a peak output of 3200W and a continuous output of 1600W. This combination provides ample power for deep bass reproduction and impactful audio experiences. The rear panel of the subwoofer features controls for gain, polarity, and a continually variable low-pass filter with a range of 63 Hz to 100 Hz, allowing users to fine-tune the subwoofer's performance according to their specific audio needs. Furthermore, a unique cardioid preset button simplifies the configuration of multiple subs, enabling effective cardioid setups for improved sound directionality without the need for external DSP devices. This feature is particularly beneficial when using two to three units in conjunction.

The Event 121A is designed for seamless integration with other DAS Audio products, including the EVENT-208A, EVENT-210A, and EVENT-212A active tops. Its phase response is coherent with these systems, allowing for precise alignment and cohesive sound across the full audio spectrum. The subwoofer includes two balanced inputs with stereo filtered outputs, which can be switched to pass-through connections, facilitating easy setup in larger audio systems.

Constructed from high-grade birch plywood, the Event 121A's enclosure is built for durability and exceptional acoustic performance. The rectangular geometry of the cabinet enhances the acoustic characteristics of the subwoofer while providing robust protection for its internal components. The enclosure is finished with DAS's ISO-flex protective coating, ensuring resilience and longevity in both touring and installation applications. The rigging hardware features M10 rigging points, allowing for versatile deployment options, while a top-located pole mount socket supports the TRD-6 optional pole mount for easy combination with full-range systems.

With a frequency range of 30 Hz to 125 Hz, the Event 121A is engineered to handle a wide variety of low-frequency audio signals, making it perfect for all types of music and sound reinforcement. It achieves an impressive maximum peak sound pressure level (SPL) of 141 dB at 1 meter, ensuring it can deliver powerful bass that fills large venues. Weighing 173.1 lbs (78.5 kg) and measuring 38.0 x 29.1 x 29.7 inches, the Event 121A strikes a solid balance between performance and portability, while rear-mounted wheels enhance its transportability. The shipping carton dimensions of 41.7 x 31.1 x 32.3 inches and a shipping weight of 184.1 lbs make it easy to handle, ensuring that this high-performance subwoofer is always ready for deployment.
