Well I have two choices rite now. I can eiither get 2 12" Treo SS subs or 2 12" Alpine Type R subs. They would go in a custom built sealed elclosure 1.25 cu/ft. I can get both for 300$ a pair. The diff is type r's would b brand new and the treos would b 3-6 months old. What would b better and louder for the money? thanks guys
