it is best to not try and correct someone unless you are 100% sure you are correct decibels are logarithmic, so a 10 dB increase = twice the volume. but what do i know, i've only competed in stereo competitions since i was 16 (11 years now) and was an IASCA judge for several years as well

Many get this confused, and most manufacturers use that confusion to sell products.

that is correct. a 3 dB increase could require the same power with double the drivers (in reference to speakers). speaking from a subwoofer perspective, if you where to double the number of subs and doubled the power supply (second amp, or an amp that is twice as powerful), it equates to about a 6 dB increase. however, those are only generalizations. the higher you go, the harder it is to increase the loudness/dB's, since it is not perfectly linear.
