Description
| Utilising a dual-chamber bandpass design, the STL-SUB incorporates two forward-facing 21-inch drivers and a single rear-facing 21-inch driver, enabling precise low-frequency directivity control. This approach significantly reduces rear sound radiation, thereby improving on-stage conditions and minimising environmental impact in outdoor or acoustically sensitive environments. The STL-SUB is primarily employed in touring, festival, and fixed installation scenarios where controlled, high-output sub-bass is essential to meet the demands of modern sound design. |
