The U21 is where the UNO series steps into serious low-frequency territory. Designed for large rooms and high-output systems, it delivers deep, controlled bass with the precision and consistency Procella is known for.
It’s not just about moving air; it’s about controlling it. The U21 keeps every hit tight, every rumble defined, even at high SPL. No excess, no blur. Just low-frequency performance that stays locked into the mix, exactly as intended.
For systems that demand more headroom, more depth, and more authority, the U21 brings the foundation in line with the rest of the experience.Part of the UNO series.
Built to keep up when everything else scales.
