Great post above about first reflection points. Could you perhaps suggest a few speakers that work well in smaller rooms, based on your experience of having heard them do so? I'm assuming a horn-loaded design would be preferred to a dynamic cone-type box speaker, but what about a hybrid system like the Klipsch Cornwall? Is it as important for lower frequencies to have the -6 dB at 45 degrees dispersion?
Cheers!
