There is a difference between buying Sonos and having Sonos professionally installed.
As an authorized Sonos dealer, we provide manufacturer-backed installation, proper acoustic calibration, and full warranty support. Our clients do not experience the drop-outs, configuration issues, and dead zones that come from self-installation. We get it right the first time.
As an authorized Sonos dealer, Dominion Security Systems purchases directly from Sonos, ensuring every product carries full warranty protection. Our certified installers have completed official Sonos training and bring 45 years of custom AV expertise to every project. We don't just install speakers — we design a system, calibrate it to your room, and ensure it performs at the level you paid for.

We walk through your home and discuss how you want to experience sound in each space.
Custom Audio Design

No coordinating between two separate companies or scheduling conflicts.
