I recently decided to get one fifteen inch for my eclipse. I know that the Fi sub is cheaper and that it is hard to get a DD. I don't know which one to get, since I have only known one person with either sub. He also had 2 bl 18" so it is kind of hard to decide. He makes his own subs and told me...
Well i want a louder system than my 2 infinity reference 12inches, and i don't want something that will sound distorted. They also have to fit in my eclipse.
