Almarg, would you please elaborate on why SPL does not decrease at 6 db per doubling of distance on planar speakers? I thought that figure was a constant for propagation in Earth's atmosphere rather than being related to the type of device producing the sound?
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.
Regards.
