Hi @Dooku74, Thank you for reaching out and welcome to the community., Regarding your concern about the ideal ceiling height of the Sonos Arc, I would recommend around up to 9 feet high to maximize the full potential of the Arc. But we can wait for suggestions and feedback from our Sonos community users who might have the same setup that you have. Also, the Sonos Arc requires a minimum of 5.5 inches on the front and sides of it with at least 2 inches between the backside of Arc and the TV when in a tabletop orientation. If wall-mounting, it is recommended to have a clearance of at least 5.5 inches between the TV and Arc.

Let us know how you get on with the advice above.

We're here to answer any further questions you have.
