wattage

I have seen prior threads on this, but none recently that can answer how many watts from an amp are truly necessary.
Take an inefficient speaker, say 86 w/db. at 98 db (which will harm hearing when sustained) 16 watts would be required. Even doubling this to account for transients would be available at 32 watts. Strickly
from an engineering standpoint, are more than 40 watts really necessary? No audiophile terms like bloom, and slam needed.

1 watt at 86 db,2 watts for 89db,4 watts for 92, 8 watts for 95, 16 for 98db, 32 watts for 101, 64 watts for 104 and so on. So yes,40 is usually sufficient but keep in mind that thx is 110db and ultra thx is 112db.

Extra wattage is always a good thing with transient peaks (symbol crashed or bass drums).
Finally, you should have a "perceived" doubling of volume for every 10db increase.
