Sonos beam TV Size

Sonos Arc vs Sonos Beam – Design

Measuring 65 x 6.5 x 10cm (WHD), the Beam is just under half the Arc's width (114 x 9 x 11.5cm). That makes the Beam better for smaller spaces. It's a unit that's more suited to smaller TVs (around 49-inches or so), while the Arc suits bigger TVs (55-inches and more).Jun 11, 2020

My TV is 75” and the Beam is just fine.

I agree, that is just marketing nonsense. The Beam works better in smaller rooms, the Bar, Base, Arc in larger rooms no matter the TV size.

My room is an open floor plan that’s 30’x25’.  I have two One’s for surround.  I think it sounds great.

Much better than the built-in TV speakers.
