I'm building out a system in a new room (and I'm new to the hobby as well) and had a question about what type of horizontal directivity design is ideal. I was looking at March Audio Sointuva and Philharmonic BMR monitors as two ends of the spectrum.
From my understanding, the tradeoff between a tight and wide horizontal directivity is a better sweet spot vs a larger soundstage. Or, to quote from Erin's audio corner directly. "trading off soundstage width for focus/imaging precision." The other trade-off I'm struggling with more is the issue related to room intereference from a wide dispersion. In theory it makes sense, a wide dispersion means more waves interacting with the room and bouncing back on you. In practice, I'm not sure what that looks like. Here is my room:

I have a wide open entryway to the right side and left side, though I have glass doors that sit open on the left side. One is probably within that 90-80 degree angle of the speaker, but I understand that low frequencies are omni directional.
At the end of the day, what type of speaker should I look to pair with a room like this? I cannot audition either the Sointuva or the BMR monitors in person, so the subjective element is harder to test. This will mostly be used with a few people, not just one person listening.
