Well Will... I find the band pass boxes (espacialy the one im getting) to be verry BOOMY, but not so clean... From what I understand (and as bass mechanic will tell you) thats not much... A sealed box sounds cleaner, but a ported box is louder! A band pass box just hits super hard! But thw W3's are realy clean sounding subs, so it should hit realy hard and sound fairly clean if its a big enoughf space Im not sure, because I know the area between the subs is important to. I know for a damn fact the ported side isnt 1.75 cubic feet thoe! So if te mid section were the speakers faces are makes up for the rest it will be buitifull!
