Help me make the decision

So I need to mount my tv.

Some details.

65in tv

Entertainment unit is 45cm high but I want to replace it in the next few years. Average tv unit height is in the 45-55cm range.

Going to also wall mount the Sonos arc which needs to have 10cm clearance from the bottom of the tv.

So at the moment I’m think of having the bottom of the tv 78cm off the ground.

This would have the Sonos 15cm above the tv unit now and a minimum of 5cm if I got a higher one. Sonos is 8cm high and then 10cm between the Sonos and the tv.

Thoughts?
