Procella Audio - V21 - 21″ High-Output Subwoofer

Procella Audio - V21 - 21″ High-Output Subwoofer
The Procella Audio V21 is a statement-grade 21" subwoofer engineered for the largest private cinemas and professional screening environments where uncompromising output is mandatory. Designed to reproduce modern film soundtracks at reference levels, it delivers immense low-frequency energy with authority and control. Its architecture reflects Procella’s cinema DNA, focusing on dynamic realism rather than exaggerated bass bloom. For installations where scale, headroom, and physical impact are essential, the V21 provides a commanding low-frequency foundation.
At the heart of the V21 is a massive 21" high-excursion woofer developed for extreme displacement and sustained high-SPL performance. The enclosure is tuned to maximize efficiency and output capability, allowing the system to generate substantial sound pressure while maintaining composure and clarity. This design supports deep, forceful bass reproduction suited to demanding LFE content and large acoustic volumes. As a passive subwoofer, the V21 is intended for pairing with powerful external amplification and appropriate DSP, enabling precise calibration to room size, placement strategy, and system goals. The heavily reinforced cabinet construction minimizes panel vibration and structural coloration, preserving definition even during intense low-frequency passages. In large theaters, multiple V21 units can be deployed to expand headroom further and smooth modal behavior, supporting advanced bass management approaches.
Procella Audio builds high-performance loudspeakers, subwoofers, and power amplifiers engineered to deliver cinema-grade clarity, wide, uniform coverage, and massive dynamic output in home theaters, studios, and professional cinemas. Their products use pro-audio compression drivers, constant-directivity waveguides, and scalable system design for immersive sound with precise imaging and deep, controlled bass, delivering professional-grade surround sound systems for home theaters. Procella amplifiers complement their speakers with optimized power and DSP presets for seamless integration.
