Beam-steering loudspeakers

Beam-steering loudspeakers: aim the sound, not the cabinet.

EDC's S-Series are software-defined columns and square arrays. Every transducer has its own amplifier and processing channel, so one cabinet forms up to four independent beams — each shaped horizontally and vertically from 1° to 120° — and clusters behave as a single source. Prices from US$7,044.

What beam steering does

Direct sound reaches the listener before the room does.

A steerable loudspeaker controls its coverage electronically instead of by cabinet shape. Energy is placed on the audience and kept off walls and ceilings, so reverberation, echoes and spill fall without turning the level down.

What software-defined adds

Three dimensions, four beams, one inventory item.

Most steerable columns control one axis. EDC shapes coverage horizontally, vertically and in depth, produces four independent beams per cabinet, and does it without shading drivers down — every transducer contributes full bandwidth whether the beam is narrow or wide. Coverage changes are a preset, not a rigging call.

The range at a glance

Column or square array — which and when.

Columns for walls, pilasters and horizontal mounting across platforms — 330 mm deep as standard, or 147 mm in the SL slim format; the SQ-90 square array for arenas, theatres and clusters; SS subwoofers that share the SQ-90 footprint and fly with it.

Common to all full-range models: coverage 1°–120° horizontal and vertical; pan/tilt ±60° in 0.1° steps; 4 beams; 20 dB off-axis rejection; FIR 2,048 taps; 8-band EQ, compressor, limiter, delay to 100 m; XLR line in/out with optional AES3 or Dante; two channels of Dante/AES67 assignable to any beam; RJ45 control on a separate port; powerCON TRUE1; ½″ birch plywood; IP55 enclosure (IP65 weatherised option); −20 °C to +50 °C. The SL models are the slim variant of each column — 147 mm deep instead of 330 mm.

How the SPL figures are measured

Published SPL is long-term peak, dB Leq (linear), for a single cabinet at the stated distance, configuration dependent. It is crest-factor independent because it is a peak figure. EDC deliberately does not publish the convergent 1 m maximum that the industry usually quotes: converging all ninety drivers into a single beam would give roughly 150 dB at 1 m, a number these loudspeakers are never operated at and which tells a designer nothing useful about coverage.

Where it is used

One range, many rooms.

Design data for consultants

Everything a specification needs, in one place.

Datasheets, Architects & Engineers text, rigging drawings, 3D models and the iOS application guide are in Resources. EASE data is exported per configuration from the EDC Pro app rather than shipped as a fixed GLL library — Resources explains why, and lists what is still in preparation.

Frequently asked questions

What is a software-defined loudspeaker?
A loudspeaker whose coverage is set in software rather than by cabinet geometry. Every EDC S-Series transducer has its own amplifier and processing channel, so one cabinet can form up to four independent beams, each with its own shape, level, delay and source. When the room or the use changes, the coverage is re-aimed from the app instead of by moving hardware.
How many beams can one EDC loudspeaker produce?
Up to four independent beams from a single SC or SQ cabinet, each shaped horizontally and vertically. The SS-1 and SS-3 subwoofers produce two. One SC-60 mounted above a video wall can cover the seating in front of it with one beam and the whole room with another.
How is this different from a steerable column?
Most steerable columns control coverage on one axis — usually vertical — and rely on the cabinet's physical width for horizontal coverage. Our algorithms shape the wavefront in three dimensions, so horizontal and vertical coverage, skew and tilt are all set in software, with every transducer contributing full bandwidth in narrow and wide configurations alike. The 3D Beamforming page explains the difference in detail.
Are the speakers for speech, music or both?
Both. The S-Series uses 1-inch soft-dome high-frequency drivers and 5-inch mid-range drivers with no compression drivers, so tonal character is preserved at any level. The same cabinets are installed for station announcements, worship services, corporate presentations and live events.
What is the frequency range?
The SC columns are rated 100 Hz to 20 kHz (±3 dB), and the SQ-90 and the slim SC-30SL, SC-60SL and SC-90SL 80 Hz to 20 kHz. The SS-1 and SS-3 subwoofers extend the system to 25 Hz. Datasheets are on each product page.
How loud are they?
Published figures are 95 dB (SC-30), 101 dB (SC-60) and 104 dB (SC-90) at 10 metres for a single cabinet, and 106 dB at 16 metres for the SQ-90, configuration dependent; cabinets cluster horizontally and vertically to form larger arrays that behave as a single source. The figures are long-term peak, dB Leq (linear), and are crest-factor independent because they are peak values. We do not publish the convergent 1-metre maximum the industry usually quotes: converging ninety drivers into a single beam would give roughly 150 dB at 1 metre, which is not a condition these loudspeakers are ever operated in and tells a designer nothing about real coverage.
Can they be used outdoors?
Yes. Standard cabinets are rated IP55. A weatherised version of every model is available and is rated IP65, with stainless-steel and aluminium hardware, a waterproof grille lining and IP65 network and power connectors. All models operate from −20 °C to +50 °C. These are our own ratings — the enclosures are not third-party tested to IEC 60529, so if a project requires a certified rating, raise it at specification stage.
Do they take Dante or AES3 digital audio?
Every model has an analogue XLR line input and output as standard, with an optional AES3 stereo input or an RJ45 Dante input. Two channels are carried over Dante or AES67, and either can be assigned to any of the four beams. Control is on a separate network port by default; if a project needs control and Dante on a single RJ45, ask us. See the Dante and AES67 page.
How are they mounted?
Columns carry eight M10 points and can be mounted vertically or horizontally with the U-brackets; subwoofers carry sixteen M10 points and a pole socket; the SQ-90 uses side and rear rigging tubes and the touring rigging frame. Rigging drawings are in Resources. We do not manufacture the rigging hardware — the brackets, tubes and touring frame are made by specialist suppliers, and the working load limits and the standard met come from the maker's documentation. Ask us or your distributor for the certificate covering the item you are specifying.
Can the system report faults?
A monitored version reports transducer, thermal and amplifier faults over the network, and the cabinets carry an inbuilt measurement microphone. This is the version specified for transport and voice-alarm applications. The telemetry interface is not yet documented for third-party systems — see the developer pages for what is and is not specified.
Are the loudspeakers certified for voice alarm or EN 60849?
A monitored version of every model is built for EN 60849 voice-alarm systems and reports transducer, thermal and amplifier faults over the network. The loudspeakers themselves are not separately certified — voice-alarm approval is granted to the installed system, not to a component — so we do not hold or publish a product certificate. Bring the certifying body in at design stage and we will supply the technical data the system certification needs.
Is there a GLL file for EASE or EASE Focus?
We support EASE, but not as a fixed GLL library. Because coverage is defined in software, each cabinet has an effectively unlimited number of dispersion patterns, and a handful of pre-baked patterns would not represent the system a consultant is actually designing. Instead the EDC Pro app exports EASE data — 3D balloon data per beam and per array — for the configuration you have designed. Design the coverage in Pro, export it, and model that in EASE.
Is there Architects and Engineers specification text?
Yes — clause text for all nine S-Series models, in Resources as an editable Word document and as a PDF. Specify from the Word version so you can edit the clause.
