[QUOTE="Jakerrr, post: 8426362, member: 637923"] for my personal use (weighing options and considering a loud future system with the limited space I have) but I figured I might as well share it doubt anyone will get any use out of this but a few may find it interesting SA 6 8's fed >4800w : ~2.45 X SPL of 1 SA-15 on 1200w 3 10's >3600w 1.89 2 12's >2400w 1.50 sq root of (product of cone-area and power ratios) = SPL ratio SPL ratio of 2 (X2 SPL of original system) = 2*(sq rt of 10) dB = ~6.32 dB gain obvious "in a perfect world" and "all else equal" assumptions made but measures were taken to decrease likelihood of "overshooting" the ratios the classic definition of SPL is the one referred to in this model that is, sound pressure in Pascals/PSI/etc a ~6.32 dB gain corresponds to pressure (or voltage, albeit with a mythical zero resistance rise) increasing by factor of 2 [/QUOTE]
