[QUOTE="Sean Thomas, post: 12045, member: 5801"] Having a debate on a dB Technology forum about adding 2 subs together and what the ouput would be. Sub is 18", self powered at 1500w, and 134dB output. Some one said that doubling of power = +3dB AND adding another speaker = +3dB. So adding another sub 1 + 1 = +6dB. I said that none of the specs matter except for the dB specs and mathmatics. In other words, it's irrellevent how many speakers and amps you have. Math says 134dB + 134dB = +3dB = 137dB. This of course does not take in phase and freq. issues that would make that different in the real world. Is my math correct? Please elaborate. [/QUOTE]
