I am impressed and entirely grateful for the many personalized responses to my query. This information is very specifically useful. More than I’d bargained for.
No decisions yet. My main house project is still ongoing so I have time before I finally furnish the new room. However, I do plan to concentrate on half the room - say 12’ across by 15’ deep for music (seating and equipment). So, the 15’ or so behind the listening position will be open space for mixed use. At the end of the day, It’s a man cave. Separate from my main home. There will be a bar involved (another “hobby”).
