Procella V21 - Subwoofer

The Procella V21 Bass Engine is a passive subwoofer positioned above the V18 for reference level commercial and residential cinemas. Twin 21 inch long throw professional drivers in the V-Loaded configuration share a 255 litre sealed cabinet, reducing distortion and cone movement while improving transient speed. It produces 139 dB continuous and 145 dB peak with extension to 18 Hz, and needs an external amplifier with DSP or PEQ control, such as a Trinnov processor, for room correction.
