The Turbosound MS121 is a high-powered, reflex-loaded single 21″ subwoofer engineered for demanding touring and installation applications. Featuring a robust 21″ neodymium low-frequency transducer, the MS121 delivers 2,000 Watts continuous and up to 8,000 Watts peak power, ensuring deep, impactful bass response with exceptional clarity. Designed with an ergonomic 4-point suspension system, the MS121 allows for rapid deployment in either vertical or horizontal orientations, making it ideal for versatile setups.

The MS121 can be suspended as part of mixed arrays with MV210-HC line array elements or used in flexible cardioid configurations with electronic delay steering, providing superior rear rejection and pattern control. This design ensures precise low-frequency management and optimized tuning for extended impact and accurate transient response. The subwoofer’s durable enclosure, constructed from 21 mm and 18 mm Baltic birch, is finished with an extremely durable semi-matte black paint to withstand the rigors of touring while maintaining a professional appearance.

Additional features include integral feet and recesses for secure ground stacking, a built-in M20 pole mount for satellite speaker configurations, and tour-grade Neutrik SpeakON STX NL4 connectors on both the rear and front panels, allowing for easy connection and rear-firing cardioid operation. Seamless integration with Lab Gruppen amplifiers and Lake DSP ensures complete system control and unmatched audio performance.
