Our listening verdict
Five stars for the way they work together.
Our personal rating for the Arc Ultra and Sub 4 pairing is five stars. We like its balance of clear voices, a spacious front soundstage and low-frequency impact that makes films feel bigger without turning the living room into a room full of speakers.
In the right space, with compatible content, it can evoke the immersive feel of a cinema. NorthTech can plan the placement and tune the system around your room, TV and listening position.

Useful answers
Before you press play.
Does Arc Ultra with Sub 4 give true surround sound?
It creates a wide, immersive front presentation with strong bass. For effects that come physically from behind the seating position, add a compatible pair of Sonos rear speakers.
Will Dolby Atmos work with my TV?
That depends on the TV, HDMI connection, source device, streaming service and soundtrack. NorthTech checks the signal path before recommending the final setup.
Can Sub 4 be placed out of sight?
Sub 4 connects wirelessly and offers placement flexibility, though the room and furniture still affect the result. NorthTech plans a discreet position and tunes the bass for the room.
