Hi,
The following is from the Stereomour description. Don't know if you saw it or not. Just FYI. My speakers are about 99 db, but are in a very large space. The Stereomour plays louder than I can listen to in my environment. YMMV.
We recommend speakers of 96+dB sensitivity for serious listening with all kinds of music. 93 db speakers are satisfactory for less stringent requirements (chamber music, soft jazz, acoustical) and smaller rooms, and we have even used a Stereomour prototypes in our lab with some 87 dB sensitivity monitors for non-intrusive background music.
