Another opinion: C.Hendricson, extracted from handbook of sound engineering." Listening for hi-fi pleasure at 3m (10ft) from the loudspeaker looses about 10db (ref 1m) and a 90 db level is certainly a typcial and pleasureable one if the music comes out clean: 100db is more typical of studio control room levels, which is often exceeded. On top of this, peak to average levels of 15 to 20 db are realistically available from a tape master, direct to disk, or digital source. Real life is this way, especially the spectacular and agresssive music that is enjoyed by and produced for the American public.
.
.A look a larger loudspeaker systems, such as recording monitors, shows that average sensitivities range from 96 to 100db/1w/1m. At 98db/1w/1m we have 88db available at 3m and need +2db or 1.6w to listen at 90db, 160w (+20db) to handle peaks. This is definitely a real world pracitcality. However, as 100db levels are reached, 1600W is required for 20db peaks. Most large power amplifiers are limited to 200 to 400w per side in sterio; 1600w may be approached by bridgeing an amplifier, but the loudspeaker may be damaged.
For 100db listening levels, a 15db peak to average will be handled by a 500w amplifier, something more realizable. "
