Madscot, I think that your setup philosophy is absolutely ideal! I’ve been considering installing a standalone Atmos system in its own room. ( But it would probably be the tool shed because that’s where I’d be living after my wife banishes me from the house.)All of my speakers are the same, Mordaunt short Genie’s, in a 5.1.2 system and it sounds amazing, if I ever get the opportunity to move to 5.1.4 i’d be looking for another pair of the same, I bought them 2nd hand but they’re the best (and most expensive new) i’ve ever had
I encourage you to snag another used pair of those Genie’s as soon as you have the funds.
