Set Your Speakers to "Small" in Your Receiver Setup Review
Posted on by LSDsmurf
Receivers and preamp/processors typically have two settings for your speakers: "small" and "large."

This setting actually has nothing to do with the size of the speakers, and everything to do with the range of the speakers.
