"...and you had 100dB 1w1m speakers To reach 80dB at the listening point say 2m away requires 92 dB at 1m..."
Outdoors yes, but indoors, once you are within the reverberant field, the SPL stays the same regardless of distance.
Plus, a stereo has two speakers and two amplifiers you need to add 3db.
BTW I believe 30db P to A is optimistic. Maybe I just listen to the wrong recordings. :-)
