Every Square Metre.
Covered. Clearly.

Speaker selection, placement, and installation engineered for the acoustic characteristics of your specific space — no dead zones, no distortion, no guesswork.

Ceiling speaker installation in an office space

What is a professional speaker system?

Speaker system design is not about putting speakers on walls. It is about selecting the right speaker type for each environment, placing it at the correct height and angle to cover the intended area, and wiring it at the right impedance and tap wattage for the amplifier driving it. Layerix conducts an acoustic assessment of every space before specifying a single speaker.

Who is it for?

  • Open‑plan offices & reception areas
  • Warehouse & factory floors (high ambient noise environments)
  • Outdoor areas & perimeter
  • Corridors & stairwells
  • Auditoriums & event halls
  • Cleanrooms & controlled environments

The Problems Professional Speaker Systems Solve

🗺️

Speakers everywhere — coverage nowhere

Too many underpowered speakers placed without a coverage plan creates a system that sounds busy but leaves dead zones in every corner. Speaker placement must be calculated — not estimated.

🏭

Wrong speaker for the environment

A ceiling speaker designed for a quiet office cannot overcome the ambient noise of a factory floor. A horn speaker designed for outdoor use sounds harsh indoors. Speaker selection is environment‑specific.

Impedance mismatch = amplifier failure

Connecting the wrong speaker load to an amplifier channel causes distortion, overheating, and premature amplifier failure. Every speaker tap wattage must be calculated against the amplifier's zone capacity.

Scope of Work

Acoustic site survey per space
Ambient noise measurement (dB SPL in relevant areas)
Speaker type selection per environment
Coverage pattern calculation per speaker model
Speaker placement plan — ceiling height, spacing, and aim angle
100V line tap wattage per speaker
Cable sizing per run length and load
Ceiling speaker installation (flush mount, surface mount, tile grid)
Wall / column speaker installation
Outdoor / weatherproof speaker installation (pole, wall, or ceiling)
Horn speaker installation for high‑noise environments
Line array installation for large open spaces
SPL measurement at commissioning to verify coverage
Impedance testing of all wiring

Speaker Type Guide

Ceiling Speaker (Flush Mount)

For: Offices, corridors, receptions, hotel rooms, retail. Coverage: 90–120° cone downward. Note: Most common type — clean finish, moderate SPL output.

Surface Mount Speaker

For: Concrete ceiling or exposed structure where flush mounting is not possible. Coverage: Similar to flush mount. Note: Visible box — less preferred aesthetically but practical in warehouses and basements.

Horn Speaker

For: Factory floors, outdoor areas, warehouses, high‑ambient‑noise environments. Coverage: Narrow, directional — high SPL over long distance. Note: Weatherproof rated options available. Not suitable for indoor speech clarity.

Column / Line Array Speaker

For: Long corridors, atria, places of worship, large open halls. Coverage: Vertical pattern control — projects sound horizontally, reduces ceiling reflections. Note: Significantly better speech intelligibility than point source in reverberant spaces.

Outdoor Weatherproof Speaker

For: Outdoor areas, car parks, sports grounds, building perimeters. Rating: IP54–IP66 depending on exposure. Note: UV‑resistant housing required for direct sunlight.

In‑Ceiling Subwoofer / Full Range

For: Music‑critical environments — hotel lobbies, restaurants, retail, event spaces. Coverage: Broadband response. Note: Requires active crossover or DSP for correct integration with satellite speakers.

How many speakers do I need?

Coverage calculation: Ceiling height determines coverage diameter per speaker.
Rule of thumb: coverage diameter ≈ 1.4× mounting height for 90° speaker.
For a 3m ceiling: ~4.2m coverage diameter per speaker.
Overlap 20–30% between speakers to eliminate dead zones.
(Layerix calculates this per room — not from a generic template.)

Our Speaker System Process

1

Acoustic Survey & Noise Measurement

Measure ambient noise (dB SPL), room dimensions, and surface materials.

2

Speaker Type & Placement Plan

Select speaker models, calculate coverage arcs, design layout.

3

Cable Sizing & Infrastructure Prep

Calculate cable gauge per run length, coordinate conduit and back boxes.

4

Installation & Termination

Mount speakers, pull and terminate cables, label all runs.

5

SPL Measurement & Commissioning

Measure sound pressure at multiple points, verify coverage, impedance test.

Client Success Story

WarehousePune

Challenge: 20,000 sq ft warehouse with high ambient noise (forklifts, conveyors) — existing ceiling speakers were inaudible in aisles.

Solution: 24 horn speakers mounted 5m high, aimed down aisles, 100V line with 30W taps, SPL target 95dB in all areas.

Outcome: Measured SPL 96–98dB across warehouse, shift announcements heard clearly from any location, dead zones eliminated.

Frequently Asked Questions

What is the difference between a ceiling speaker and a horn speaker?
Ceiling speakers provide broad, gentle coverage for quiet environments (offices, hotels). Horn speakers are high‑output, directional, for noisy environments (factories, outdoors). Using a horn speaker in a quiet office sounds harsh and is overkill.
How many ceiling speakers do we need per floor?
Depends on ceiling height and required SPL. For a 3m ceiling, speakers spaced 3–4m apart give full coverage. We calculate exactly during site survey.
What is a 100V line speaker and how do I choose the tap wattage?
100V line speakers have a transformer with multiple tap settings (e.g., 3W, 6W, 10W). Higher tap = louder but requires more amplifier power. We calculate required tap wattage based on ambient noise and mounting height.
Can we use the same speakers for background music and PA?
Yes — most commercial speakers are designed for both. The DSP routes music at lower priority, PA at higher priority. Music resumes after announcement.
What is IP rating for speakers and which rating do we need outdoors?
IP rating = ingress protection. IP54 = dust‑protected and water‑resistant (splashes). IP66 = dust‑tight and powerful water jets. Outdoor speakers should be at least IP54; for exposed areas, IP66.
What is SPL and what level do we need in our facility?
SPL = Sound Pressure Level (loudness). Typical office: 75–80dB SPL. Factory: 85–95dB SPL. Emergency announcements must be +15dB above ambient noise. We measure and verify during commissioning.
Can speakers be used in a cleanroom or controlled environment?
Yes — specialised cleanroom speakers have sealed enclosures, no particle shedding, and are compatible with HEPA filtration. We can supply and install cleanroom‑rated speakers.
What is a line array speaker and when should we use one?
A line array is a vertical column of multiple small drivers. It controls vertical dispersion, projecting sound horizontally with minimal ceiling reflections. Use in long corridors, atria, or reverberant spaces where speech intelligibility is critical.
What happens if one speaker fails — does the whole zone go silent?
100V line speakers are wired in parallel. If one speaker fails (open circuit), the remaining speakers continue working. If a short circuit occurs, the amplifier channel may shut down — we install zone fuses to isolate failures.
How long do commercial speakers last before replacement?
Indoor commercial speakers: 15–20 years. Outdoor weatherproof speakers: 10–15 years depending on UV exposure. We include regular inspection in AMC.
Can we add more speakers to an existing zone without replacing the amplifier?
It depends on remaining amplifier power capacity. If the amplifier has spare wattage (total zone load < amplifier rating), yes. We document headroom during design.
