I just want to suggest here where you would choose an M3 or M50 vs. other Axioms.

If you want low spatial resolution, you would choose an M3 or an M50; an M50 if you don't want to use a sub and an M3 with a sub.

A good question is "When might you want low spatial resolution?" I've tried to answer that question. I've listened to vinyl on Spotify, tape and bad recordings on the various speakers. I've also listened in the background while cooking, reading etc. I've found that low spatial resolution is actually more satisfying to me for background listening and very bad recordings.

I don't know if what applies to me applies in general to other listeners. If it does apply generally, it may be something Axiom wants to consider as a feature in the form of a soft switch in the LFRs and a hard switch in the passives.
