You seem to have some knowledge on what your doing, but I would suggest sitting on here doing some searching for a couple hours before you go cutting more wood.

Or just stuff them all in sealed and see what happens since you already made this big *** box.

you are tilling me that a 1.67 3ft is to small when it's not, yes 1 15 can go in 1.67 Sealed

1.67ft^3 is still pretty small for a 15" woofer. I'd start at 3ft^3 each sealed and go from there. If you don't like the way it sounds, add volume to the box(2x4's are an easy way) and see if you like the sound of a smaller box better.

As for ported, I wouldn't go any lower than 3ft^3....3.5-4ft^3 each tuned ~35hz would probably be optimal.

x2. a 15 can go in that small of a box an it'll play but will it sound good? Highly doubt it, wont have much low end unless you run more than rms to each sub. Back to the Drawing/Designing boards.

Is the OP just doin this to be able to say hes runnin 9 15's? With the cubes listed, 3 15's ported would be equal, if not superior.

let me guess his box is to small

With out hearing it in person, yes it could be.Some people think playing the harmonics louder then the fundemental is a good thing not saying that is what is happening though.

I dont think the poly fill will do much for you,you are probly going to get a upper bass bump and deminished low end. How ever with that much cone area it still might work out good.Try it with out the poly fill first.

One or two 15's in that size box may not have much low end. Cram 9 woofers in a vehicle and it might pick up some low end from the large amount of cone area, even with the small boxes.

Aren't KOB's 12's in tiny boxes, I'm sure his truck gets low due to the cone area/power.
