Disagree.


You are wrong,
When you Double the number of speakers - increase of +3 dB
this is what's considered to be Exponential Growth,
because it is also the same increase as Double amplifier wattage - increase of +3 dB so by adding an additional speaker qualifies as such an Exponential Growth.

i never had a teacher in audio/video, but i thought (stupid me!) that an increase in dB was logarithmic; never heard of +3 dB to be "Exponential Growth". the two are immensely different.
