15 subwoofers would produce 15 times as much power. log1015 = 1.176; to convert that to decibels, you have to multiply it by 10, so you get an increase of 11.76 decibels, in other words, 180 + 11.76 = 191.76 decibels. Since the 180 decibels probably includes some rounding, it makes sense to round the final result, too - for example, to 192 decibels.
