my bad did you mean 350-400 for both subs or for each. As far as 2 15's or 4 10's for sq purposes plus it has more cone area i would go with the 4 10's they will be more precise and accurate but they will not be able to drop as low as 15's. And most of the 15's mentioned have good sq, except the MTX it is not the greatest. But it depends on the install.
