Yes, the 15's should have a slightly greater motor force also. Now everything makes sense

False. Unless they use different motors for different size subs then 2 10s has more motor force than 1 15

Lol, yeah, I meant 1-15 vs 1-10

2-10s is potentially around 70% greater Bl depending on how the VC's are wired.

why do the 15's cost so much more? The 10's are $169 then the 12's are $179 then the 15's go up $30 to $209

Well, one 15" has more effective cone area than two 10"s.
