Clarity without distraction

Houses of worship

Looking for loudspeakers for a reverberant church or sanctuary? EDC's software-defined SQ-90 and SC columns aim up to four beams at the congregation from a single position, keep energy off stone and glass, and are commissioned with an AR app. Two SQ-90s replaced six ceiling speakers at St Ann Catholic Church, Charlotte; a pair plus one SS-3 covers Westport Baptist Church including under the balcony.
Houses of worship

Houses of worship demand intelligibility, consistency and restraint. Speech must remain clear across the congregation. Music must be present without overwhelming the space. Architectural reverberation must be controlled without altering the building.

EDC systems deliver even coverage while keeping sound energy away from reflective surfaces. A single SQ-90 or SC column forms up to four beams — nave, transepts, balcony, choir — each aimed and shaped for its area, so the direct sound reaches every seat before the room does. The experience remains focused, natural and inclusive for every seat.

What changes for the congregation

At Westport Baptist Church the previous system — several loudspeakers pointed in different directions around the sanctuary — made the pastor sound “like a voice coming down a hallway”. Two SQ-90s and one SS-3 from a single location now cover the floor, above and below the balcony, with the near-field presence of a much smaller room. At St Ann Catholic Church, where audio panels were not an option in a 1955 interior, two SQ-90s replaced six ceiling loudspeakers and removed the multiple arrivals that had made services hard to follow.

Designing the system

Coverage is designed in the Pro App by walking the seating areas in augmented reality, predicted at thousands of positions, then measured in the room and corrected. Changes to the service format later are a preset, not a rigging job.

Frequently asked questions

How many speakers does a typical sanctuary need?
Often far fewer than a distributed system. St Ann Catholic Church replaced six ceiling loudspeakers with two SQ-90s; Westport Baptist Church covers the whole floor, above and below the balcony, from a pair of SQ-90s and one SS-3 subwoofer.
Can the speakers be hidden or finished to match the building?
Cabinets are compact and can be custom-finished; the slim SL columns are 147 mm deep. For heritage interiors where wall treatment is not permitted, controlling the coverage is the alternative to treating the room.
Can one system handle both traditional and contemporary services?
Yes. Beams are recalled by preset, so a spoken liturgy, a choir and a contemporary band can each have their own coverage from the same cabinets.
Who installs EDC systems in churches?
Regional representatives and integrators across the United States, and distributors in the UK, Australia and New Zealand — see distributors. EDC engineers support design and commissioning.
