In-Ceiling Speakers: Placement, Spacing and Amplifiers

How many ceiling speakers you need, where they go and what powers them.

Published 2026-08-30 · 5 min read · By the 1800Install team

Why in-ceiling?

In-ceiling speakers disappear into the room and spread sound evenly, which makes them ideal for background music.

Spacing matters

Speakers spread sound in a cone. Higher ceilings can space speakers farther apart. Our speaker layout tool estimates how many you need for a room.

Stereo or background?

For background music, evenly spaced speakers with one volume control work well. For focused listening, pair speakers left and right of the seating.

What powers them?

In-ceiling speakers need an amplifier. A Sonos Amp can power them so they join your Sonos system.

Wiring

New construction is the easiest time to run speaker wire, but existing homes can often be fished.
