Is there some form of baseline for the height setting of the Arc and Era 300 speakers? What I mean is for example a +1 for each 30/40 cm of ceiling height? So for a ceiling of 270 cm the best setting would be around 7 or 8.  And yes I am aware I could just experiment what sounds best to me but I am just wondering if there is a best practice.

Those are very ideal distances and the ideal ceiling height. You shouldn’t need to set the Height Level any higher than +2 to +4.

The other recommendation is not angling the Era 300s. Keep them straight directly facing the front wall as recommended by Sonos.

How tall is your ceiling? Is it flat and without obstructions? How far are you seated from the Arc and Era 300s?

It’s about 270cm, unobstructed. Arc is about 2,5 m from seating position and the Era 300’s are about 1,5m angled towards the main seating position.
