Where to place the speakers
Even coverage that keeps speech clear at every seat, whatever the room.
Overview
The goal of speaker placement is simple: make speech clear and evenly heard from every seat.
Even coverage matters more than volume. With good coverage, speech stays clear at normal listening levels.
—————————————————————————————————————————
Start with the essentials
Prioritise coverage, not loudness
If you feel the need to turn it up, the room usually needs better coverage, not more volume. Evenly distributed sound:
Improves intelligibility
Reduces listener fatigue
Keeps audio consistent across the room
Know where sound actually needs to go
You don't need perfect wall-to-wall coverage. Focus on:
Seating areas
Presentation zones
Wherever people listen and speak
Unused corners don't need speakers.
Match the speaker type to the ceiling height
Choose the speaker that brings sound closest to listeners, not the one with the most power.
RoomDesign Ceiling: best for 2.4 to 3 m (8 to 10 ft) ceilings
RoomDesign Pendant: best for tall or open ceilings
RoomDesign Surface: best when ceiling mounting isn't possible, or when you want front-focused sound
Keep all speakers on the same level
Use one speaker type per room wherever possible. Mixing ceiling, pendant, and surface speakers leads to uneven sound and unpredictable results.
Tip: Use Pleneo Planner to plan speaker placement for your room.

Room-by-room speaker placement
These are the most predictable layouts for clear, professional sound using RoomDesign speakers.
Medium meeting room (10 to 16 seats, single table) — Ceiling or Surface
Use four RoomDesign Ceiling speakers, arranged in a square covering the table
With RoomDesign Surface speakers, mount two speakers left and right on the front wall, high and angled slightly downward

Large meeting room (16 to 24 seats, long table) — Ceiling, Surface, or Pendant for high ceilings
Install two rows of speakers running the length of the table
Keep spacing consistent
In tall rooms, use RoomDesign Pendant in the same pattern

Boardroom (wide or boat-shaped table) — Ceiling or Pendant
Use four RoomDesign Ceiling speakers, arranged in a square covering the table
For wide tables, use two parallel rows
In high ceilings, use RoomDesign Pendant to bring sound closer

Training room, U-shape (participants face inward toward the instructor) — Ceiling, Pendant, or Surface
Place four RoomDesign Ceiling speakers above the open centre of the U
Optionally bias slightly toward the instructor
For Surface speakers, mount front-left and front-right

Training room, classroom style (rows facing the front) — Ceiling or Pendant
Install six RoomDesign Ceiling speakers, spaced evenly front to back
Use the same pattern for RoomDesign Pendant in tall rooms

Auditorium (tiered seating, single presenter) — Surface or Pendant
Use RoomDesign Surface speakers left and right of the stage for directional sound
In tall rooms, RoomDesign Pendant works better
Note: ceiling speakers are generally not recommended here, because of the height and distance.

—————————————————————————————————————————
In summary
Speaker placement is about coverage, not volume:
Put sound where people sit
Keep spacing even and symmetrical
Match the speaker type to the ceiling height
With good placement, audio stays clear and consistent at every seat.
