Help finding a subwoofer

I want a subwoofer that meets the following criteria.

1. 12 inch driver max size. Or 8 inch driver plus passive driver. Or 10 inches driver.

2. Android or IPhone or iPad app to change settings anytime I want.

3. Speaker high level inputs.

Please if you know any let me know.

System is for music primarily movies completely secondary. I really have two systems that can use the sub(s). Main drivers do not go low. On set is Cain and Cain single Ben with Fostex 8 inch driver. the other Martin Logan Motion 15, these are nice small speakers that Are not expensive.

Thanks for your contributions
