I don't agree that smaller sound box does not give you clarity for orchestra listening. I listen to a lot of orchestral work on my small speakers. They sound great. I think what is leaking is the very low register bass which do make the orchestra sound "fuller". However, if you listen to orchestra playing in concert halls, most of the time the bass is not as strong as we hear on records. On the other hand, I think many people using larger speakers also have larger listening environments which help to produce more roomy sound. If you have a small room for your listening enjoyment, larger speaker doesnt neither as the resonant of your room really doesnt allow you to produce low bass.
Another prove of the fault of smaller speakers can not resolving complex information is that ear phones, which being even smaller, are excellent monitoring devices. The issue of resolving complex information is not the size but the quality of production.
