I'm sorry there ace. I didn't attack you directly... pardon the assault on the neophyte question. I'm very helpful, just kinda smug about it.

Oh we got that part.

Right see that is exactly backwards. If you want subs to 'drop' then you *want* a ported box. If the enclosure is constructed properly, the benefit is not one of volume, the benefit is in extended bass-response. The port is tuned to a certain frequency, and that frequency determines the overall response of the speaker system... in the case of a sealed box you place a defacto 6db/octave slope on entire response curve, so you really *do* lose those low frequencies you're looking for. Only an improperly constructed ported enclosure will produce *less* low end than a sealed enclosure. Any given pair of 12's will have great low end if you stick them in a ~2.5 cft box and port it to 35hz.

You didn't provide enough information for this to be useful..i.e. telling us how thick the wood is that was used to build the box... and that is an awful lot of boring math to do.

The alpine 605 gives you great control over the subs, hertz and all but the alpine type e’s cant handle the lower hertz.

I'll tell ya what. If you go out and post a link to the owners manuel/pdf for those Alpine subs, I'll graph the subs for you in WinISD and show you some possibilities. "I'm finished!" - Daniel Plainview

My friend had a couple of the older white cone Type E subs in a big prefab ported box and a Coustic 400DB amp...400 watts to those subs and they were banging..cept for the crappy high tuned ported box. Type E's like big ported boxes..like 4-5 cu ft for a couple 12's
