ok my box is 4.3 cubic foot, slot port, tuned to 28hz and i have a old school 15 w6 as i said in my post not to long ago and it still wasnt enough i think i will either go with a 15" tempest, or a 15" sx but if u can give me a price for a sx, or if u can give a another good 15" sub for around the price of the tempest becasue had to spend little money on the girl firends system but if i have to i will fork the money for the sx.
