[QUOTE="Kyle_Keating, post: 7081035, member: 582385"] small signal sensitivity - the one you see in the spec's is simply the cone area, BL, Resistance and Moving mass. The entire formula is derived from those 4 numbers and here is how they work: double the moving mass - lose 6dB double the BL - gain 6dB double the cone - gain 6dB double the Re - lose 3dB so simply put, if you add another woofer identical to the one you own what do you have? twice the BL +6, twice the cone+6, twice the Re -3, twice the moving mass -6. net gain = +3dB in raw sensitivity. Large signal sensitivity largely depends on many other things but some of them include the xmax limitations and compliance limitations. If you run out of BL or compliance (suspension) linearity, this will reduce your sensitivity. Other variables apply that largely relate to frequency, system design and some of AC concepts, but that's the gist of it from a simple standpoint. [/QUOTE]
