Beam-steering loudspeakers
SQ-90
90-channel software-defined square array — the flagship.
Full-range loudspeaker with 90 individual transducers, 90 amplifiers and 90 DSP channels in a 425 mm square cabinet. Up to four independently shaped beams, horizontal and vertical control, clusterable into larger arrays that behave as one source.
US list price. Project and regional pricing through distributors.
- Dynamic horizontal and vertical control, adjustable between 1° and 120°
- Four unique beams of sound in different directions, each with its own acoustic shape
- Clusters horizontally and vertically to form larger arrays as a single point source
- 81 high-frequency and 9 mid-range drivers, each individually amplified and processed
- Ethernet network control and monitoring; optional Dante or AES3 input

The SQ-90 is a high-powered, software-defined loudspeaker designed for large venues and complex audio environments. Ninety individually amplified and processed transducers in a single square cabinet form up to four independent beams, each shaped horizontally and vertically to fit a defined audience area — a balcony, a stalls block, a platform, a foyer — while keeping energy off walls and ceilings.
Cabinets cluster horizontally and vertically to form larger arrays that behave as a single point source, so an installation can grow from one SQ-90 covering a sanctuary to a cluster covering a 5,000-seat arena without changing the design approach. Davidson College’s Belk Arena, Mastercard’s New York headquarters and Time Matters Entertainment’s touring inventory are all SQ-90 systems.
What the numbers mean
Each of the 81 high-frequency and 9 mid-range drivers has its own amplifier and processing channel. Unlike steered columns that broaden a beam by shading drivers down, every SQ-90 transducer contributes full bandwidth whether the beam is narrow or wide, which is what lets one cabinet deliver concert-level output with the transient behaviour of a studio monitor.
Commissioning
Coverage is designed and verified in the EDC Pro App: audience areas are drawn in augmented reality on an iPad, the app predicts level and frequency response across thousands of listening positions, and the settings are pushed to the cabinet over the network. Measured response from the iPad microphone closes the loop.
