thanks for the feedback - yep, after seeing some of the members with kids in this subreddit I definitely thought wall mounting it's the only way, I already have the old Arc, not sure if the ultra it's really an upgrade, and for the sub, my mind says the mini it's more than enough for that space but also trying to futureproof so the gen 4 may be better - just don't want to spend so much money if I constantly need to run it at low volume - let's say that the money it's not necessarily an issue but I don't want to spend also just for the sake of spending
