There was a time when I wondered aloud here what defined a small room. The impetus at the time was the reference Dynaudio made to such things in their literature for the Audience line. They published a table of recommended minimum amplifier ratings based on small, medium and large rooms. The Audience 82 can reportedly get down to something like 26Hz, so maybe that's why they made recommendations for it in medium and large rooms, but not small...not being able to accommodate the wave length.
