Overview

The APSi‑Pro‑S is a compact three‑way arrayable point‑source loudspeaker designed expressly for fixed installation environments that require wide vertical coverage, high output, and the ability to integrate seamlessly into scalable system architectures.

While it shares the same core acoustic DNA as the APSi‑Pro‑D, the APSi‑Pro‑S provides a 30° vertical dispersion, making it the ideal building block for short‑throw zones, under‑balcony reinforcement, nearfield coverage, and any installation where broader vertical reach is required without sacrificing clarity or control. Its acoustic engine is built around CODA’s Dual Diaphragm Coaxial Curved Wave Driver (DDC), which reproduces mid and high frequencies from a single coherent source. This driver couples into the magnetic InstaFit APS‑COUPLER, forming a unified, pattern‑controlled wavefront that maintains consistency across the entire array. As with all APSi‑Pro modules, horizontal dispersion can be precisely tailored using interchangeable couplers, allowing system designers to match coverage to the architectural demands of the venue.

The low‑frequency section of the APSi‑Pro‑S mirrors the performance of the APSi‑Pro‑D, employing two 10‑inch high‑excursion neodymium drivers with carbon‑fibre diaphragms for exceptional stiffness and low moving mass. These drivers are thermally bonded to a shaped aluminium baffle that also forms the cabinet’s reflex ports, implementing CODA’s Dynamic Airflow Cooling (DAC) technology. DAC actively extracts heat from the motor structures, increasing continuous power handling and significantly reducing power compression — a critical advantage in permanent installations where systems must operate at high output for extended periods. This ensures that the APSi‑Pro‑S maintains consistent low‑frequency performance down to 50 Hz, even under demanding long‑term operating conditions.

With its 30° vertical coverage, the APSi‑Pro‑S is optimised for applications where a single module or a small number of modules must cover a large vertical area. It can be deployed on its own, used in compact arrays, or combined with APSi‑Pro‑D modules to create hybrid configurations that blend 10° and 30° elements. This flexibility allows system designers to construct arrays that follow the geometry of the venue, delivering smooth, predictable coverage from the front row to the back of the room. Although compact and visually discreet, the APSi‑Pro‑S is engineered as a true installation‑grade system, with rigging and accessories designed specifically for permanent deployment rather than touring use.

A key advantage of the APSi‑Pro installation series is the unique Array Keeper accessory system, which has been purpose‑built to address the long‑term serviceability challenges of fixed installations. Traditional array frames require removing lower loudspeakers to access a module positioned higher in the array, resulting in unnecessary labour, extended downtime, and increased risk during maintenance. The APSi‑Pro J‑Frame eliminates this issue entirely. Its mechanical design allows any individual loudspeaker — including APSi‑Pro‑S modules — to be removed, inspected, or replaced without disturbing the units beneath it, even when the system is fully installed. This capability is invaluable in theatres, clubs, houses of worship, and multipurpose venues where access is limited and maintenance windows are short. The J‑Frame ensures that APSi‑Pro systems remain practical, maintainable, and operationally efficient throughout their service life.

When paired with the APSi‑SUB, the APSi‑Pro‑S extends system bandwidth down to 28 Hz, delivering full‑range performance suitable for music, speech, and high‑impact applications. The subwoofer can be flown above or below APSi‑Pro arrays or ground‑stacked, offering flexibility for venues with architectural constraints or strict aesthetic requirements. Together, APSi‑Pro‑S, APSi‑Pro‑D, and APSi‑SUB form a coherent installation‑optimised platform that combines point‑source clarity with arrayable scalability, supported by advanced driver technology and a rigging ecosystem engineered for real‑world practicality and long‑term serviceability.
