Nice perspective
@dolynick and when you say that large speakers worked, how did you manage the speakers in the room? Did you do anything specific?
It was a bedroom so there was little that could be done. They were stuff in where they could go and it was relatively corner restricted. They were my Paradigm Studio 100 v2s - a little shy of 4' tall, ~100 lbs each and rated 25Hz (DIN) - 20kHz in a room that was 13'x11' or so if I recall. Far more speaker than needed for the room and not a scenario to really get best out of them, but I still enjoyed them during their time there.
I believe the Elysian 4s are even larger. They have 10" or 12" woofers if I recall and I think they're also taller than the old Studios.
I'm not remotely a treatment expert, but you can probably do some stuff to help the mid to upper ranges being a bit too lively/reverberant in a smaller room like that. Bass you'll have to rely on placement to try and tame, but I suspect a small square room is going to be peaky and there's probably not a lot you can do about that other than just tuning down the bottom end in EQ given their output potential. Fortunately, room EQ is far more ubiquitous nowadays. It was barely on the radar yet in my case.
