# What mistakes happen in luxury home theatre projects?

> The most expensive mistakes are made before any speaker is chosen: wrong room shape, no acoustic shell, no isolation from adjacent walls, HVAC routed straight through the ceiling, and seat geometry that ignores sightlines. A reference home cinema is 60% architecture, 30% acoustics and 10% gear.

## Short answer

The most expensive mistakes are made before any speaker is chosen: wrong room shape, no acoustic shell, no isolation from adjacent walls, HVAC routed straight through the ceiling, and seat geometry that ignores sightlines. A reference home cinema is 60% architecture, 30% acoustics and 10% gear.

## Visual explanation

Section drawing of a private theatre with floating floor, decoupled walls, acoustic shell and isolated HVAC paths — versus a typical 'painted black' room.

## Real-world example

A client had already invested in a flagship projector and a high-end speaker brand. The room sounded harsh and bright because rear walls were bare plaster. We added a properly tuned acoustic shell, isolated the ceiling and re-pointed the seating row — same equipment, completely different room.

## Lessons

- Get the shell right before specifying any speaker.
- Never let HVAC ducts pass directly through the cinema ceiling.
- Lock seat geometry to the screen and reference axis early.
- Spend on calibration, not just badges.

## FAQ

### Do I need a dedicated room?

For reference performance, yes. Open-plan media rooms trade fidelity for flexibility.

### Is Dolby Atmos worth it?

Yes, but only with the correct ceiling height, layout and acoustic prep.

### Projector or large OLED?

Projector for cinema scale and ambiance; OLED for daylight rooms.
