first of all, i dont know why you'd want to combine sub sizes. second, i'm not sure that the 10 "feeding" the 12 air is a good idea. i'm assuming that you have the 12 getting power, and the 10 getting power to. this is a good concept if you're using a passive driver though. a passive driver setup is one driver that has power going to it, sharing a common chamber with a passive driver, or one that isn't hooked up and doesn't have a magnet or terminals. since they're sharing a chamber, the air that the driver with power going to it moves also moves the other driver.


you on the other hand have two different sub sizes, moving different amounts of air. thats your first mistake. i wouldn't do that personally because since you're moving two different amounts of air, i think that sounds bad. theres cancellation.

secondly, there is no passive driver. you have both subs getting power to them. they both take strokes at the same time. so if they're both taking an outstroke, theoretically the air that the 10 is pushing behind the 12 thats already on an outstroke, could push the 12 past it's xmax taking these two enclosure concepts into consideration. hope that makes sense
