Hi guys

In abit of a dilema, if specs for 2 subs being the same in everyway but one is 12" and one is 15", would there be any differences in the sound. Like i think the bigger one would be more deeper as its a larger face or so i could be wrong.

Reason i ask cause i want to buy this sub that is 12" with its own factory ported box which i think would be sweat as it would be made exactly to the subs specifications to gain from porting. Or i could go for the 15" version of that sub but it doesn't have a factory box to go with it so i would have to bundle it with a non ported 15" sub box. Would also like to know you guys knowledge of the two different setups what benefits and differences.

Thanks
