Procella Audio – P15Si – 15″ Sealed Subwoofer

Procella Audio – P15Si – 15″ Sealed Subwoofer
The Procella Audio P15Si is a 15-inch sealed subwoofer created for serious cinema environments where control, scale, and integration matter more than sheer cabinet size. Built around a high-excursion driver and engineered for use with external amplification, it delivers deep, authoritative bass while maintaining the composure demanded by reference-level playback. Its sealed acoustic suspension alignment emphasizes transient precision and tonal accuracy, allowing low frequencies to reinforce the soundstage without masking detail. For dedicated theaters and performance-driven media rooms, the P15Si provides a disciplined foundation that complements Procella’s high-efficiency speaker systems.
At its core, the P15Si features a robust 15-inch long-throw woofer housed in a rigid, sealed enclosure designed to support accurate low-frequency reproduction. The acoustic suspension design promotes tight damping and linear behavior, reducing overhang and preserving pitch definition in complex bass passages. Intended for pairing with suitably specified external amplification, the subwoofer offers flexibility in system design, allowing integrators to tailor power delivery and headroom to room size and performance goals. The cabinet construction minimizes unwanted resonance and limits coloration, maintaining clarity even at elevated playback levels. This configuration supports precise bass management integration in multi-channel systems, helping maintain phase alignment and consistent crossover behavior with main and surround channels. Whether deployed as a single unit or in multiple-sub arrays to improve in-room response uniformity, the P15Si delivers impactful low-frequency effects and convincing musical weight while remaining controlled and articulate.
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.
