Imix IM221BS Dual21 Inch PassiveSubwoofer

Imix IM221BS Dual 21 Inch Passive Subwoofer - a high-output dual 21-inch passive subwoofer for the largest PA systems, concerts, and stadium-scale bass reinforcement.

The IM221BS is a large-format passive subwoofer housing dual 21-inch drivers, delivering exceptional low-frequency output for major events, outdoor concerts, and large stadium or arena PA systems. The 21-inch driver format provides deeper bass extension and greater SPL potential than smaller configurations, making the IM221BS suited to applications where maximum sub-bass impact is required. As a passive subwoofer it is driven from a dedicated sub-band amplifier output with an active crossover managing the frequency split. Typically deployed in pairs or arrays for even coverage across large venues and outdoor sites.
