Alright thanks. Ya i was told to port the 15 but i wasnt told that it would hit any harder. thanks for the comment. What you think about 2 Perfects in a bandpass box. They said it will be louder but not with the sq. Im lookin for somethin to replace my Pl2-212 system and something that hits harder than my friends 2 Audiobahn Aw1206t subs in a sealed box powered by 2 A8000ts. What ya think i should get to outpower his out of my options?
