Perform

PS-850

The PS-850 is a powerful and flexible double 18" subwoofer from the Perform series. The passive sub with direct dispersion and vented enclosure is the perfect complement to the Focus Venue modules and the PT-70 speaker. In conjunction with the DSP-driven DI amplifiers, it provides precise and powerful sound for concert halls, clubs, stadiums and open-air events. The PS-850 is perfectly suitable for horizontal, vertical or end fired sub-arrays, but also for cardioid setups.

To ensure optimal performance and operational safety, the PS-850 needs to be operated with Fohhn DSP amplifiers including the corresponding speaker presets.
