U15

A 15" sealed subwoofer engineered for accurate low-frequency extension in mid-sized rooms. The U15 delivers the depth, output, and control needed to support full-range cinema playback without overwhelming the space.

Reference low end for mid-sized rooms.

The U15 sits at the heart of the UNO Series, designed for residential and professional cinemas where headroom and definition both matter. Its 15-inch long-throw driver in a 48-litre sealed cabinet delivers deep, controlled output with the precision Procella systems are tuned for.

Whether deployed as a single sub or as part of a multi-sub array, the U15 maintains tight transient response and even distribution across seating positions, supporting the front-stage and surround speakers with a clean, articulate foundation.

For systems that need scale without sacrificing accuracy, the U15 is where the UNO Series finds its balance.
