To get a good sound, or particularly a good loudness, in a small place is a lot to do with the proportionality of the speaker power output relative to the room size. You can have huge speakers sound awful in a small room and vice versa.
Levelling the playing field in 'amateur sound tech' (mostly good craftspeople who are just doing what they can with limited time/resources) is an active area of research in acoustics and DSP. I recommend Dr Josh Reiss of QMUL (where I'm based) for more on this. Check out his work on automatic audio engineering. Machine learning is very appropriate to this area of work:
