# EDC Acoustics

> Focused precision. Loudspeaker and spatial-audio technologies that control where sound goes, how it is perceived, and where it does not belong.

EDC Acoustics designs software-defined beam-steering loudspeakers (the S-Series: SQ-90 square array, SC-30/60/90 and slim SL-30/60 columns, SS-1/SS-3 subwoofers), Volumetric Wavefield Synthesis systems, and — coming soon — Octoid and Quadoid loudspeakers. Every transducer has its own amplifier and DSP channel; each cabinet forms up to four independently shaped beams with 1°–120° horizontal and vertical control. Headquarters: 2840 Guilder Drive, Suite 200, Plano, TX 75074, USA. Founded in Australia. Awards: InfoComm 2025 Best of Show (SVC), ISE 2025 Best of Show (SVC), Best Immersive Experience ISE 2025 (rAVe), InfoComm 2023 Best of Show (SVC, Mix).

## Technology
- [3D Beamforming](https://www.edcacoustics.com/technology/3d-beamforming/): Controls where sound goes. A method of controlling acoustic radiation in three dimensions so that every listener receives the same level, the same frequency response and the same spatial image — and the room is left out of it.
- [Volumetric Wavefield Synthesis](https://www.edcacoustics.com/technology/volumetric-wavefield-synthesis/): Controls how sound is perceived. A method of reproducing sound so that spatial imaging, level and frequency response are consistent for every listener within a defined volume — sound that originates inside the listening space rather than at its edges.
- [Octoid & Quadoid radiation](https://www.edcacoustics.com/technology/octoid-quadoid-radiation/): Controls where sound does not go. Loudspeaker technologies that confine sound to a defined fraction of a sphere — a quarter (Quadoid) or an eighth (Octoid) — across the full audio band, in a compact form. New technology, coming soon.
- [Software — Pro, Rapid and AR](https://www.edcacoustics.com/technology/software/): Predict, visualise, verify. EDC's software tools predict, validate and verify sound behaviour across an entire audience before a system is installed — then measure the room and close the loop. Pro is the full design environment; Rapid deploys with the same engine.

## Case studies
- [Davidson College Wildcats, Davidson, North Carolina, USA](https://www.edcacoustics.com/case-studies/davidson-college-belk-arena/): A 5,300-seat, multi-level, highly reverberant arena. Integrator Clarity selected SQ-90s to shape the wavefront to the room and minimise hangs.
- [Edwards Lifesciences, California, USA](https://www.edcacoustics.com/case-studies/edwards-lifesciences/): Zoned audio across an LED wall from four SC-60s mounted horizontally above each section — one beam per zone, a second beam for the whole space.
- [Mastercard, New York, USA](https://www.edcacoustics.com/case-studies/mastercard-global-office/): A large, highly reverberant headquarters space with multiple modes of use. SQ-90, SS-3 and SC-60SL cabinets achieved a speech transmission index above 0.85 in a room with an RT60 over six seconds.
- [St Ann Catholic Church, Charlotte, North Carolina, USA](https://www.edcacoustics.com/case-studies/st-ann-catholic-church/): A 1955 parish church with a reverberation problem and no appetite for acoustic panels. Two SQ-90s replaced six ceiling loudspeakers and covered the whole floor from a single location.
- [Sydney Trains — Central Station, Sydney, Australia](https://www.edcacoustics.com/case-studies/sydney-central-station/): Heritage-listed interchange serving 250,000 people a day. Horizontally mounted SC columns cut cross-platform spill, improved intelligibility and needed far fewer cabinets than a distributed system.
- [Time Matters Entertainment, Plano, Texas, USA](https://www.edcacoustics.com/case-studies/time-matters-entertainment/): An AV rental company needed coverage for a large outdoor corporate hospitality space, speech to music, with minimal noise pollution beyond the site. Sixteen SQ-90s, twelve SS-3s and SC-60 delays did it.
- [Westport Baptist Church, Denver, North Carolina, USA](https://www.edcacoustics.com/case-studies/westport-baptist-church/): Scattered loudspeakers pointing in every direction made the pastor sound like a voice down a hallway. A pair of SQ-90s and one SS-3 now cover the floor, above and below the balcony, from one position.
