Cone area calculator

I'm glad you figured it out. If I have learned anything on this forum, audioholic (and a few other members on here) know their shit and if they tell you you are wrong, you most likely are. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

yeah but the math worked... somewhere along the lines it went wrong, and after i explained where i was coming from even they were confused(cuz it made sense when it shouln't have), but the computer doesnt lie, we needed that from rashaddd lol

I was just browing through the T/S specs of the Mach 5 SPL ... the 12 has Sd = 433.7 cm2 , and the 15" Sd = 754.8 cm2 ... that means 2 12"s having 867.4cm2 would only have an advantage of 112.6 cm2 over a single 15"... is this a substantial advantage? (I haven't looked alot info subwoofer parameters)

It's more no matter how you put it, I'd go with the twelves for sure unless you'd rather just power one speaker

Well, since they both have 17mm of excursion we can calculate that two 12's will have a Vd of 1.47L, the single 15" a Vd of 1.28L

20*log(1.47/1.28) = 1.2db

So the 12's are theoretically capable of 1.2db more output based on linear displacement.
