[QUOTE="Pete, post: 420488, member: 552802"] the dB scale is logarithmic. 1 12" with 200 whats is 3 dB quieter than either 1 12" with 400 watts OR 2 12" with 200 watts. It is also true that 3 dB is twice as loud, but our ears perceive twice as loud as 10 dB. Oh, and as for it being easy to achieve new spl records... you can quickly see how out of hand it would get to raise 3 dB when you get to high spl and power levels. Start with 2 12" subs and 500 watts. to add 3 dB you need either 4 12" subs OR 1000 watts. To add 3 dB again you would need to use 8 12"s or push 2000 watts. Add 3 dB again and you have a total of 16 12" subs or 4000 watts. One more time would be 32 12" subs or 8000 watts. We added either 30 subs or 3500 watts to gain a total of 9 whole dB... ouch.
