This is a very interestting thread. However it would be good to hear JA's views on this especially in regard to your final paragraph. I am not sure that he picks up on Speaker Asylum .

Voltage sensitivity is formally specified as the sound pressure level
produced at 1m when a single loudspeaker is fed 2.83V in an anechoic
chamber. That is the number I quote in my reviews, modified by applying
a B-weighting curve that rolls off the extreme highs and lows. (That is
to prevent a speaker with extended bass, for example, measuring as being
more sensitive than a smaller speaker that produces the same spl in the
midrange and thus is equally loud with music.)
Manufacturers often specify the output of two speakers not one, or they
measure the spl in a room rather than anechoically, in order to be able
to publish a bigger number. With a speaker that has a non-flat response,
they often specify the spl of the highest peak in the response, also to
be able to print a bigger number. All of these methods are dirty pool, in
For more, see my comments on measuring sensitivity on pages 3 and 4
of the article linked below.
Exactly. Lots of baloney rationalization as to why sensitivity should be 2 speakers and/or in a room, but it's just to give a mistaken impression with big numbers.
I asked in the comments section (last couple of posts in comments) of this review, and got some response.....
