We've had really good results with 5 cubes per 8 spoke 15. We have the loudest jeep soft top in the world with a pair of DD 9515s. Bet Boyd's wall full of 12s.

dam really...

i have been really thinking of going with diffrent subs.

dont get me wrong i like sq for what you get for the price i like.

but im looking for more, more spl, more nastiness lol...

and i take that 5^3 is gross right ?

thats what my box is now tuned at 34.

if i could afford it i would love to go with 4 - 15" but.........

Just saying what we use for 8 spoke subs with great results. Two 9915s doing 55s sealed on the dash no wall also.

You'd model it and make it right -- not bigger or smaller.
There comes a point where more airspace doesn't get you anything other than an unnecessarily big box.

this!

OP what subs do you have, current box size/port area, and how much power are you stepping up to?

DD's seem to do well in big boxes as they have a rather stiff suspension. Most subs won't be happy in an overly large enclosure on a lot of power...

It's not got much to do with the suspension. DC subs are stupid stuff and don't like them.

All the DD/AQ set ups I've built have been on the large side cuz of the stiff suspension. And I agree that DC soft parts leave a lot to be desired but I have built a few loud set ups with them. Just that the guys go thru recones on a regular basis...

Box modeling will show the point where the frequency has reached its limits no matter how big you make it.

Until you stick it in a car and it all changes.
