I know this is a really novice question but........

My reciever and DVD set-up both have a feature regarding speaker size. You can select large or small but they really do not have any guidelines for what determines whether a speaker is large or small. Speakers obviously come in a variety of sizes so what constitutes large or small? Is there a more "technical" definition for speaker size that will help me set the correct size in the future? My current configuration is Bose 201's in the front and a VCS-10 center channel. I have a Panasonic HE-75 for the reciever. Any tips on how the speakers should be set?
