Well said. Many audiophiles make the mistake of putting a too large speaker in their room.
Resulting potential issues:
- bass problems
- soundstage problems (a speaker needs to be able to fully 'disappear' in terms of localization of sound, many large speakers can't unless in a very large room)
- problems with driver coherence at the listening seat (if you have to sit closer than the distance where drivers truly blend)
I also have a 26m2 living room (7.2 m x 3.6 m, 2.6 meter high; 24 x 12 x 8.5 feet), and I have Reference 3A MM DeCapo BE monitors and a REL sub. I would be reluctant to try anything substantially bigger than that in my room. My dream speaker (mentioned earlier in the thread):
Reference 3A Reflector monitor.
