My wife is a speech pathologist, with some audiology background,
and she brought home one of those sound-level meters.  We tried
it out with my stereo, and were able to easily get a reading
of 70db with an indicated amplifier output of less than 10 watts/channel
(maybe closer to 5 watts/channel, but I don't recall for sure).

All this through my Infinity RSa loudspeakers, which I never
thought to be particularly efficient.  Now maybe we weren't operating
things properly, etc., but I suspect it may have something
to do with the small size (8'x16') of the room.  Any theories?

Sorry about my earlier comments about cow colleges.  Some of
my co-graduates took offense.  We get by.
