A planning link — not a quote.
Plan view, drawn to one scale in both directions. The room is 20.00 m deep by 12.00 m wide, with the cabinet on the front wall and the listener 15.00 m down the axis. L-Acoustics A15 Focus has a nominal horizontal pattern of 90°, so the covered shape is a wedge whose apex is at the CABINET, not a circle around the listener. The wedge is drawn at half that angle either side of the axis. At the listener's distance that wedge is 30.00 m across — 15.00 m either side of the axis. That width is the published figure, and it is the only coverage quantity this tool establishes. The room is 12.00 m wide there, so one cabinet covers the full width with 18.00 m to spare across the two edges combined. The wedge is the nominal beamwidth drawn with straight edges. It is not a measured -6 dB contour, and it is a HORIZONTAL quantity only: no vertical coverage, and no covered area, is claimed here. This cabinet's vertical pattern is 10°, and the difference between the two is exactly why a single circular figure would misstate the covered patch.
What this result means
One L-Acoustics A15 Focus at full output reaches about 120 dB where the listener sits, 15.00 m away — 35 dB more than the 85 dB normally designed for Conference / auditorium speech. Each cabinet covers about 30.00 m across there. One cabinet spreads 90° horizontally, and from a front-centre position that spans this room's width — so it takes 1 cabinet.

Assumed for you
- This figure treats the cabinet as a point source — about 6 dB quieter each time the distance doubles. A line or column source only behaves that way well beyond its near field; closer in it falls nearer 3 dB per doubling, so the SPL printed here is a floor for this cabinet rather than an estimate of it.
- One cabinet covers that seat; nothing is added for a second box reaching the same listener.
- The room is an empty rectangle at one height — no balcony, columns, soffits or furniture.
What this does not establish
- Not a seat-by-seat prediction — a whole audience is modelled in the manufacturer's own software.
- Not a verdict on whether speech will be understood; that follows from reverberation and background noise, which are measured.
- Not a specification, a bill of quantities or a compliance judgement, and it says nothing about an evacuation or voice-alarm system.

A-Series install-friendly line array. Horizontal coverage is field-adjustable via Panflex to 70 degrees, 110 degrees, or an asymmetric 90 degrees (35/55); the 90-degree figure carried here is the mid setting, so re-check coverage against the setting actually specified. Vertical is 10 degrees. Sensitivity is NOT recorded: L-Acoustics publishes none, verified across eight official documents. RMS power is the manufacturer's published 446 W, which is a figure calculated from mean impedance over the usable bandwidth rather than a thermal endurance rating; no peak figure is published. Maximum SPL is published per amplified controller (LA4X / LA7.16 / LA12X).

- Confirmed ceiling height
- Finishes & absorption in the space
- Final loudspeaker model & dispersion
Feasibility
120 dB max at the listener carries 35 dB over the 85 dB target — comfortable headroom; a smaller cabinet may be more cost-effective.
A planning link — not a quote.
Quick answer
Speaker coverage planning estimates how many loudspeakers a room needs and roughly where they sit so sound pressure stays even across the seating area — derived from the speaker's horizontal coverage angle, the room's dimensions and the listener distance. This planner returns an indicative SPL estimate and box count for source-cited models; it does not ask for or model mounting height. It is a planning reference, not an acoustic design.
When to use
Early scoping of a PA, conference or auditorium audio system to gauge speaker count and spacing before an acoustic design.
When not to use
For reverberation and room-treatment questions, use the Acoustic RT60 Calculator. Final tuning depends on measurement, DSP and commissioning on site.

Amplifier matching for K-array and KGEAR passive cabinets
The question after coverage is almost always the amplifier. K-array publishes a matching table stating the maximum number of each passive cabinet that may sit in parallel on one amplifier channel, and the KGEAR datasheets state suggested amplifiers, low-frequency pairings and sealing accessories. 308 of those statements are reproduced below across 46 cabinets and 7 amplifier column headings, each with the document it was read from.
Everything here is the manufacturer’s statement, quoted. Nothing is derived, averaged or extrapolated, and no amplifier specification is mixed into these cells — a cell is a count, the amplifier names are the column headings the source document prints, and “KA104 / KA208” is one heading covering two amplifiers exactly as printed. Use it to shape a question for the manufacturer’s own matching table, not as a substitute for it.
Manufacturer's matching table
Every cabinet against every amplifier column
“Max Recommended Number of Speakers in Parallel per Amplifier Channel”. The manufacturer's matching table is colour-coded and the band was not recoverable from the extracted text, so a count here is the stated maximum in parallel per amplifier channel — not a recommended quantity, and not a substitute for the amplifier's own load calculation.

Plan with confidence
From an SPL estimate to a system that sounds right everywhere
The planner gives an indicative SPL, horizontal coverage width and box count — a starting point for design, not a final specification. These notes turn that into a brief: what stays fixed, what to confirm in the room and what to send us for a coverage review.
Planning notes
- SPL at the listener is the free-field floor — real rooms add reverberant energy, so a lively room runs louder than the prediction and a treated room runs close to it.
- Dispersion versus room geometry decides coverage uniformity — the right pattern is what separates 'good everywhere' from 'good only at the engineer's seat'.
- The box count is a first-order estimate against rectangular coverage; the manufacturer's prediction software (Soundvision, ArrayCalc) is the deliverable on the real project.
- Most install cabinets roll off above 60–75 Hz — a subwoofer pair is part of the brief, not an afterthought, for music programme.

Before final design, confirm
- Room drawings, ceiling height, finishes and absorption (RT60 behaviour).
- The SPL target for the application and the seating layout.
- The final loudspeaker model, dispersion and the amplifier / processor architecture.
- Sub-pairing, delays and the rigging / structural assessment where applicable.
What to share with us for review
- The floor plate, the seating layout and the SPL target.
- The brand preference, if any — or just paste the planner's share link.
- Whether the room is speech-priority or full-band music programme.

SPL is the headline. Dispersion and room behaviour are the conversation.
The calculator answers 'how loud and how many'. The engineering underneath — dispersion pattern vs room geometry, direct field vs reverberant field, processor configuration, amplifier matching, cabling discipline — is what separates a system that sounds correct everywhere from one that sounds correct only at the engineer's seat.

Deployment observations
The observations3 notes — engineering detail behind this section
- SPL prediction by inverse-square law is the floor of a coverage conversation, not the ceiling. The calculator gives you SPL at the listener distance assuming free-field propagation; real rooms have reflections that add reverberant energy, often 3-10 dB at the listening position depending on RT60 and absorption. For lively rooms (RT60 > 1.2s) the actual perceived SPL exceeds the calculator's free-field prediction; for treated rooms the calculator's prediction is conservative-accurate.
- Dispersion pattern determines coverage uniformity. A 100° × 10° line-array element covers a wide horizontal seating block from elevation with controlled vertical energy — sermons, auditoria, live events. A 110° × 110° pendant ceiling speaker covers a circle of floor area — restaurants, retail. Specifying the wrong dispersion for the room is the most common cause of 'great seats and bad seats' in installs.
- Sub-pairing changes the brief. Most line-array and install cabinets roll off above 60-75 Hz. For live amplified music (kick drum, bass guitar, electronic music) a subwoofer pair extending to 35-45 Hz is mandatory. The calculator's frequency-range row tells you whether the cabinet stands alone or needs sub support.

- Amplifier sizing convention, and the population it applies to: for a LOW-IMPEDANCE passive cabinet, provision the amplifier at 2-4× the speaker's continuous rating for clean headroom and to avoid clipping (which damages speakers more than peak power does). A 700 W cabinet is typically driven by a 1400-2800 W amplifier per channel. That convention does NOT transfer to a 70/100 V constant-voltage system: there the amplifier sees the sum of the transformer taps actually selected across the run, so the multiplier is applied to the tapped total and never to a single cabinet's published wattage. The planner withholds an applied-power figure on constant-voltage models whose tap settings it does not hold, precisely so this convention cannot be applied to a number that may be a tap.
- Constant-voltage (70 V / 100 V line) vs low-impedance is an architectural decision, not a preference. A constant-voltage line tolerates very long cable runs (100 m+) at minimal loss and lets many cabinets share one channel at chosen tap settings — the default for distributed BGM and paging in restaurants, retail and large public spaces. Low-impedance (8 ohm typical) delivers higher peak SPL and lower distortion — the default for live events, premium worship and serious AV. Sizing, cabling and amplifier selection differ on every count, so the decision comes before the model, not after it.
03 · Lifecycle implications
Lifecycle implications
Read the lifecycle implications2 notes — engineering detail behind this section
- Driver lifecycle: quality install cabinets (K-array, d&b, L-Acoustics, JBL Pro) hold their performance for 15-25 years in climate-controlled rooms. Touring cabinets typically refresh on 8-12 year cycles driven by transport wear. Ceiling 100V systems run 20+ years if the room humidity is controlled.
- Processor and amplifier refresh: 8-12 years for system processors (BSS Soundweb, Symetrix, Q-SYS); 10-15 years for amplifiers. Plan amplification as a refreshable layer; the speakers and the structural cabling outlast the electronics by 2-3x.

How to read this tool’s output
Stage 3 (design). Use to scope speaker quantity, brand and amplification before BOQ. For final design specify manufacturer prediction software (Soundvision, ArrayCalc) against actual room geometry.
The assumptions, limits and reference architectures behind this
What an engineer should know
The assumptions behind the numbers this tool produces.
- SPL coverage planner across a source-cited public catalogue spanning pro touring, commercial audio and architectural speakers. Computes predicted SPL at listener distance via inverse-square law, the horizontal coverage width at that distance from the -6 dB dispersion figure, and a quantity recommendation from the angle the room's width subtends at a front-centre position.
When this tool is the right one
The project moments and room types this is built for.
- Auditorium speaker scoping at design stage.
- House-of-worship sound-system brief.
- Restaurant / retail BGM zoning.
- Live-event audio specification.
What changes the answer in practice
Field conditions that move the result away from the planning figure.
- Free-field SPL prediction is conservative — real rooms add reverberant energy. Treated rooms match the calculator; lively rooms exceed it.
- Amplifier sizing convention: provision at 2-4× speaker RMS for clean headroom and to avoid clipping damage.
Defensible starting architectures
Vendor-neutral reference points, not a recommendation to buy — the right answer is the one that survives your site survey.
- Premium worship / auditorium: K-array Pinnacle KR202, L-Acoustics A15 Focus, d&b Y8 — install-grade line array with controlled vertical dispersion.
- Live event / touring: K-array Mugello KH3, L-Acoustics K2, d&b V8, JBL VTX A8 — high-output line array with sub support.
- Distributed BGM (restaurant / retail): Fonestar ASPC-650T, Ecler IC6 — ceiling 100V line for long-run distributed audio.
Common mistakes
Failure patterns we see on real projects.
- Specifying 100V line speakers for live amplified events — designed for distributed BGM, not concert SPL.
- Ignoring sub-pairing requirement when the chosen cabinet rolls off above 60-80 Hz.
- Choosing dispersion pattern against the wrong room shape — 110° × 110° pendant in a long narrow auditorium = bad seats at the back.
What this tool does not do
Deliberate limits — where the estimate stops and design begins.
- Driver lifecycle: 15-25 years in climate-controlled installs; 8-12 years for touring service.
- Processor / amplifier refresh on 10-15 year cycle.
Where this tool fits
The building types this output is calibrated for — and, where we have said so, the ones it is not.
· Why it matters
A speaker coverage calculator that quotes 'how many cabinets' without telling you the SPL at the listener is missing the question. One that doesn't carry dispersion data is missing the answer. This one runs inverse-square SPL math from each cabinet's rated maximum SPL, surfaces the horizontal coverage width at the listener from the -6 dB dispersion figure, and recommends quantity by comparing that dispersion against the angle the room's width subtends. 32 brands · 523 public models, 355 checked against a source naming that exact model · sources cited per model.
· Frequently asked
Speaker coverage —
what people ask first.
Why does SPL drop so much with distance?
Inverse-square law — which is the point-source case. Every doubling of distance drops SPL by 6 dB in free-field: 100 dB at 1m becomes 94 dB at 2m, 88 dB at 4m, 82 dB at 8m. A line array or column speaker is different. In its near field it radiates a cylindrical wavefront and level falls closer to 3 dB per doubling, and where that near field ends depends on array length and frequency — for a 2 m source it is around 1.5 m at 250 Hz but nearer 23 m at 4 kHz. The calculator applies the point-source law to every model, so on a line or column source the SPL it prints is a floor for that cabinet rather than an estimate of it. Real rooms then add reverberant energy on top (typically 3-10 dB at the listening position), so the measured drop is less dramatic again.
Why are line-array dispersions so narrow vertically (5-15°)?
Because line-array geometry is designed to control vertical coverage so that distant rows hear the same level as front rows. Each cabinet narrowly aims a slice of the audience; assembling 6-12 cabinets in an array creates a continuous vertical coverage from front-row to back-row with controlled level taper. Horizontally line arrays are typically wide (80-110°) because the seating block is wide.
What's the role of Soundvision / ArrayCalc / K-array prediction software?
Manufacturer prediction software models the actual room geometry (audience block, ceiling, side walls) against the actual speaker positions, splays and processor settings. The calculator gives you a first-order SPL estimate; manufacturer software gives you per-seat SPL prediction with reflections and array taper modelled. Use the calculator for early-stage scoping; specify Soundvision / ArrayCalc as a deliverable on the actual project.
What about Kasper Sound and other brands not in the database?
The public catalogue now carries 523 public models across 32 professional, commercial and architectural audio brands — 355 checked against a source naming that exact model, the rest held as indicative. Kasper Sound and other domestic / international brands are added only when we have usable datasheets. Send us the brand and model spec via /contact; we add verified profiles in editorial batches rather than publishing half-verified data.
How accurate is the quantity recommendation?
It is an angular comparison, not an area one. The room's width subtends an angle at a front-centre position; that angle is divided by the cabinet's horizontal dispersion and rounded up. No area, no circle and no coverage figure enters the count. It is a first-order estimate and tends to be conservative, because adjacent cabinets overlap and their outputs add — about +3 dB where two boxes cover the same seat, which the room simulator's energy sum models and this angular count does not. It also says nothing about whether one cabinet is loud enough to reach the back row — that is the separate SPL question the headline answers. For final design always run the manufacturer's prediction software against actual room geometry.
