Turbosound TS-MS121 Description

The Turbosound TS-MS121 is a powerful 21" passive subwoofer that brings deep low-frequency extension and precise control to portable, installed, or touring sound systems. Utilizing a neodymium driver in a reflex-loaded design, it achieves a remarkable frequency range down to 20Hz with a peak output of 142dB. Designed with cardioid deployment in mind, the MS121 offers advanced arraying options including electronic delay steering for optimized rear rejection. The subwoofer features a 4-point rigging system for suspension—either standalone or in combination with MV210-HC line arrays—supporting up to 9 units at a 10:1 safety factor. The rugged enclosure is crafted from Baltic birch plywood with a tour-grade finish, ensuring reliability in demanding conditions. For ground stack setups, integrated feet and stacking recesses provide added stability, while the M20 pole mount allows use with satellite speakers. NL4 connectors on both the rear and front panels simplify signal routing for standard or cardioid applications.
