Hi @Prejus, Thanks for reaching out, and welcome to the community. Regarding your question about the Sonos Arc placement. 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. Also, Arc is designed to support tabletop and wall-mounted configurations. It cannot be wall-mounted above a TV as well because Arc has two up-firing speakers within it that sound best when positioned either on a tabletop, or wall-mounted below a TV. We can wait for recommendations and feedback from our other Sonos community users who may have the same configurations for further assistance. 

Keep us posted on how it goes and we're here to answer any further questions you have.
