Stevdart, partly correct.
3dB requires a doubling of power.
6dB is a doubling of voltage (thus a doubling of amplitude / pressure), 4x the power, and sounds "twice as loud" to people who work with audio, and know what 6dB sounds like.
10dB is 10x the power, and sounds "twice as loud" to the average person.
The 6dB/10dB points can be argued (most literature simply says that 10dB sounds twice as loud) but 3dB really doesn't sound twice as loud.
You're ABSOLUTELY right though about having to double the number of speakers (and amps) for an extra 3dB. It really seems pointless doesn't it? :)
