the WAMM was Wilson's first speaker system, and no, it wasn't very

I've heard this before, and it always strikes me as odd. A full
symphony orchestra in a hall isn't very loud. Reproducing the dynamic
range of a full symphony orchestra as heard from, say, Row J isn't
that hard. I'm not talking about reproducing the levels as heard by
some poor musician sat in front of the brass section, which is
something you really wouldn't want to do at home anyway.
From the reference I could find [1], Marsh (1975) reported 95 dB at
Chicago's Orchestra Hall, and maybe the peak factor is 5-10 dB, giving
100-105 dB peak. Olson (1967) reported peak SPLs of 100 dB. Granted,
this might be a bit of a challenge at 25Hz, but according to the
spectral plots in that paper there's little energy at such low
frequencies.
