From Klipsch, CS I got the adjustments and from there, as I commented, I took measurements with a digital sound meter during movie soundtrack playback. The conditions were, an Audyssey corrected listening environment of 3,500cuft, volume control of a Marantz, SR5007 set to 0dB during dialogue and action sequences. No readings were made during peak explosions, etc., as at the time, there was only action oriented sound reproduction.
In candor, after a long discussion with Klipsch, describing why I should deduct 14dB for the environment described, that's what I did. I realize there's the world of the anechoic ideal and then there's the open room such as being out on the sandy beach, speakers facing the ocean. In this case our listening environment is a real world living room, main LP is ~11' from the speakers as the room is replete with reflective walls, floors with throw rugs and untreated cathedral ceilings with walls opening up to the front entryway and kitchen on a side wall which, as you know, reduces the sensitivity rating of the speaker accordingly because of sound pressure being bled off.
