[QUOTE="RobGMN, post: 8898469, member: 683408"] If you have two 6" woofers moving at a rate of 60Hz, with one moving 4" per cycle and the other moving 6" per cycle, will they both sound the same? Will they both pressurize the air the same? I'm harkening back to a wave tank I saw. You could adjust frequency and stroke of the piston that drove the "wave bar". Leaving the frequency the same but changing the stroke mad a very big difference in the wave produced. Liquid dynamics. I don't know the translation into SPL, though. I would think more excursion at the same frequency = more SPL. [/QUOTE]
