Hi guys! I like to ask for a little help.Right now in my car i got a Digital Design 12 inch subwoofer.Its a 3512 with dual 2ohm voice coil.i got the box design the first time from the DD webpage.Its a full size 2.5Ft box and i like to keep the exact same port area and tuned hertz the box because its sound very very load and good in my car.
Right now i got a second subwoofer and i dont have enough place in the boot to put the same size of the box. I mean i have the place but its cant be the same dimension..... I want 2 seperate box for it because sometimes i need to take out one of my subwoofer...
The size i can have in the car is 19X20highx19deep. (The top baffle where the subwoofer and the port go next to it is 19x19inches)
Can somebody help me out with the port design to have exactly the same tuned hertz on this dimension? and the same inside air space also? Im sorry i cant build the box but with the calculations is not easy
The original dd box design is here:
Thank you for the help!
