I’m nuts as I move a pretty hefty system between two rooms in my house. I have an Instagram page that documents the whole journey
I saw some of the photos. Looks like quite a project. One more question for clarification:
Is your plan to regularly move this system between these two rooms, or is this a more-or-less permanent move from the larger room to the smaller one? If the former, it looks like you may have enough equipment for two systems. Perhaps do that instead?
…what I'm getting at is that it's difficult to make a recommendation that will work equally well in two different rooms. If folks here could know where this system will ultimately land or at least spend most of its time, I imagine you'd get more helpful answers. In my experience, one must choose the right loudspeakers for the room to get the best results.
Using the Legacy Aeris as an example, my experience with it's smaller sibling (the Focus XD) taught me that you have to sit at least ten feet away for all six front-firing drivers to integrate seamlessly as a point-source. That is impractical in your smaller room.
