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 coverage angle, mounting height and listener distance. This planner returns an indicative layout and SPL estimate for datasheet-cited models. 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.

Plan with confidence
From an SPL estimate to a system that sounds right everywhere
The planner gives an indicative SPL, coverage radius 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.
Share your drawings, BOQ, site details or the tool result with TechnoGuru for a written estimate after drawings, a BOQ or a site review.
Where this connects — services
· Engineering advisory · Speaker Coverage
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
- 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.
Operational notes
- Amplifier sizing convention: provision the amplifier at 2-4× the speaker's RMS rating for clean headroom and to avoid clipping (which damages speakers more than peak power does). A 700 W RMS cabinet is typically driven by a 1400-2800 W amplifier per channel. The calculator's applied-power slider lets you sanity-check the SPL prediction against a realistic amplifier configuration.
- 100V line vs low-impedance is an architectural decision. 100V line tolerates very long cable runs (100m+) at minimal loss — default for distributed BGM in restaurants, retail and large public spaces. Low-impedance (8 ohm typical) delivers higher peak SPL and lower distortion — default for live events, premium worship and serious AV.
Lifecycle implications
- 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.
· 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 the inverse-square law SPL math against manufacturer sensitivity, surfaces the coverage radius at the -6 dB dispersion axis, and recommends quantity against rectangular coverage area. 51 brands · 559 verified public models · sources cited per model · last verified 2026.
· Frequently asked
Speaker coverage —
what people ask first.
Why does SPL drop so much with distance?
Inverse-square law. Every doubling of distance drops SPL by 6 dB in free-field. A 100 dB SPL at 1m becomes 94 dB at 2m, 88 dB at 4m, 82 dB at 8m. In real rooms the reverberant field adds back some energy (typically 3-10 dB at the listening position) so the perceived drop is less dramatic, but the calculator's free-field prediction is the conservative engineering floor.
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 559 verified public models across 51 professional, commercial and architectural audio brands. 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?
The quantity figure assumes uniform circular coverage at the -6 dB dispersion axis on the listener plane. It is a first-order estimate and tends to be conservative (recommends slightly more boxes than a manufacturer's prediction software would, because real coverage circles overlap and audio sums coherently). For final design always run the manufacturer's prediction software against actual room geometry.
