How to Choose Audio System for Cafe and Restaurant: 2026 Guide

Why a Cafe Needs Proper Audio

Music in a cafe is not "background noise" — it's a tool that affects average check, dwell time, and overall guest perception. Cheap computer speakers or one Bluetooth station in the corner create a "comfort zone" only within 3-4 meters; distant guests hear distorted sound with volume drops.

A properly designed system sounds evenly balanced in any spot of the room.

Main Rule: Distributed (100V) Audio, Not Hi-Fi

Cafes, restaurants, and shops use distributed audio (100V), not home Hi-Fi (8 Ohm).

The amplifier outputs 100V signal over thin cable; each speaker has a transformer stepping voltage down to driver level. This allows 20 speakers on one line without quality loss.

How Many Speakers

A standard 6W ceiling speaker provides even sound within a 2.5-3 m radius at 2.7-3 m ceiling height:

30 m² cafe — 4 ceiling speakers × 6W = 24W amp needed

50 m² cafe — 6 speakers × 6W = 36W + 30% reserve, take 60W

100 m² restaurant — 10 speakers × 6W = 60W + reserve, take 120W

200 m² hall — 16 speakers × 10W = 160W, take 240W

A 30% power reserve is mandatory — otherwise the amp runs at its limit and fails quickly.

Outdoor Terrace

For outdoor use, weatherproof IP54+ speakers are required:

Klipsch AW-650 — two-way 6.5" weatherproof, wall-mounted under canopy

Common Mistakes

Underestimating speaker count. "Two big ones in corners is enough" — no. Guests at far walls hear music 4× quieter.

Hi-Fi speakers in large halls. Work at home, sag in volume in commercial use.

Cheap Bluetooth receivers. Lag or disconnect = silence/clicks for guests.

No zoning. Bar area should be louder than dining — needs separate lines and zone amp (M730T, M7830T).

Bottom Line

Most cafes work with DomAudio M130T + 4-6 S430T/S640T speakers. For premium sound, go Klipsch PSM-650-T.
