band pass can boost up the lows up to +-3db. the only trouble with this is, when u put a bandpass closure in a boot(another closure) it will make things worst. another theory is when a ported closure in a boot (seal closure), it will automatically act as an band pass is some setup this is just what u get from too much ICE. pardon my ignorance

if u put your woofer like the first pic there, u will have a hell lots of vibration! the floor board will be shaking like earth quake and your metal body will vibrate too. except if u put thick mat like the superlon under your woofer to reduce the vibration. but its not 100% sealed so its not that perfect interm of performance.

i would recommend ditching the woofer and get a real good component set and test it out first. some quality component set would have enough bass that your friend tot you are running a 8" sub. or even a 10" sub.
everything need to blend in, like your amp, your crossover and component... try the focal utopia or K2 series.. if u have the budget.

if ur purpose of getting a sub is for blasting (sound pressure level SPL) then you definately need a big enclosure or a very good free air type of sub. all boil down to your wallet....

some how I don't agree...

you need subs to play low frequencies.... no matter how good the comps are, you won't be able to hit the lows because the midbass have it's limit.

I don't listen to choir or acapella songs... so bass sound is a must

Anyway, I've already decided my choice in the 1st page....

dude... found this on the net...

Does subwoofer placement matters in sound staging?

I noticed some different subwoofer trunk positions but afraid these setups are not good for SQ...

for me it is not neccesary to place the sub in the middle.just like your pc speaker...the sub will be either right/center/left and other directions that are appropiate.actually i am also in the same scenario with soulfly,thinking to put the sub but reluctant to put those big box into the boot coz i need those space.picture no 1 should be ok for me.
