best box?

what kind of enclosure would be best for four audiobahn 12s? i know each box has its differences...
im looking for sound quality and loudness (imagine that)

what kinda sound would i get with a bandpass (im thinkin speakers facing down, ported on the bottom, plexiglass top (the frame of the speakers is chrome..so it'd look cool)

i could also do ported, or sealed.....i like deep bass (a lot of the music i listen to has deep rolling basslines, not punchy hits) so i think ported would be better than sealed for this..am i correct?

right now im leaning towards the bandpass idea. i'd also like a custom enclosure for the back of my car (92 civic hatchback) but i dont know how easy it would be to fit 4 12s, and have proper air space..so if anyone has any pictures of something like that, i'd appreciate it also :)

im up for any suggestions / comments...

kthx,
Justin

for sound quality, i would stay away from band-pass. i'd go for either the sealed or the ported box. how bout half and half? 2 ported and 2 sealed? its just and idea;)

my dad actually gave me that idea....2 ported 2 sealed...i didnt know if that would screw things up or not...maybe thats what i'll do.....no bandpass tho?

i think you should go with a ported box

yeah, im going to do 2 ported and 2 sealed......i have the box for 2 ported made already, so i just have to add on to that (with wood i already have) to the other side, for the two sealed (im gonna have the two ported facing up, and 2 sealed facing the hatch) just gotta get my measurements right for the sealed portion, and im set...i already have the wood and everything....just a matter of building it (read: my dad building it)

hopefully we'll have it all done either tomorrow or the next day, since i have off of work one of those days :)

....then you'll hear me in boston ;)

hehehehe

kthx justin
