4. In order to get 3dB additional output from a speaker, the amplifier input power must be: a) Doubled
b) Tripled
c) Quadrupled
d) Bi-Amped
I wondered why i blew my speaker amp a few years back, and now I know why. Although the amp will go all the way to 80, that is 115dB if a 60dB signal is provided at some base level (or something like that...i have no idea how it works...). But it is not meant to go all the way up to 80. It takes twice the power to raise the system 3dB. That means twice the heat and twice the stress on the parts. Bam.
