I need help with a design. I'm tryin to fit 4 12s in a sealed enclosure in my hatch but, i don't want them to fire up, forword or directly to the side. My space comes to 36" wide 17.5" tall and 66" deep. All my designs had canelation flaws So i gave up on them. Can someone please help me?

You have a ton of room. You could go to a 7th order bandpass and just see ports!!! I would think any bandpass design could hide the subs completely. You just need a good formula to design the box correctly.

this would be nutso just 4 6" ports firing forward or rearward

"i don't want them to fire up, forword or directly to the side."

so what then? angled baffle? down firing is you only direction you could fire, there is only up, front rear or side to fire the woofers.

i want the subs to fire to the rear in a sealed box also the measurement of 17.5" tall has changed to 22.5" tall. sorry about the change.

Hmm... Why don't you just downfire them... and port it.

i'm having trouble get 4 12s to fit in the way i want but, if you think it would be easier to fit 6 12s then i'd consider it

I drive a ford probe witch is a 2 door hatchback, with the subs firing up they sounds ****** to me. as easy as it would be to just fire all 4 up i don't want to money and time. now can someone help me or design a box for 4 rear firing 12s that will fit the measurements 36" wide, 22.5" tall and 66" deep or is it not possible?

umm i would say impossible because u need like 50 inches wide

u only have enough to barely even get 3 subs if that firing back unless if possible u could not make the box as deep and angle the front like a v

you know what i am saying so 2 subs on each side and angle the box like a v

How can you not like ported box's?? They're "better" for rap.. To each his own I guess ;)

not impossible just make the front baffle like an V shape u can fit all 4 12's rear firing that way. make 2 baffles 1 baffle that hold 2 12 each. then angle them sort of like the woofers are firing at each other. thats the only way u going to fit 4 12s rear firing. and honestly i love sealed boxes, but u can also get an ported box to sound BETTER! and they can also have flat responses and not have large peaks. if it were me id fire all 4 subs up and have my port facing the rear tuned to 28hz. lower tuning the flater ur response will be majority of the times and will sound **** good too.

i wouldnt say just rap ported is good for what every type of music you listen to. just tunning is the major part.

Spend the cash you have now on two better 12's (or better yet, one 15), and save yourself the hassle. It'll be easier, louder, and cleaner
