Kicker CVR12

I think you've got it, and two 6-inch vents is perfect.

Now lets play a little. Look at your amplitude response, notice its above 6dB (thats OK). Just out of curiousity, tune the port lower and see if it helps the excursion (hard to tell but it looks like your at 29 or 30, which is OK) Lets shoot for 27 or 28 on the excursion. But dont let your peak (amplitude resonse) go below 6dB.

Vent velocity is good, you DONT need larger ports.

 

Hmm. The box I was planning to build was 2 chambered.. 2.25 cubes per chamber with 1 slot vent per chamber (2.5" x 12.5" and 17.5" long). The box is going to be tuned to 40 Hz. Each CVR12 will be powred by a kicker 400.1

EDIT: Hey is there any way you can make the width 43", the height 14", and just mess with the depth? And by the way, do you have to pay for this program?

 

BassBox Pro currently sells for around $120. Electrolytic might know someplace cheaper but I dont.

Yes, you can leave height and width alone and adjust depth for size. I pesonally don't like seperate enclosures for each woofer but in your case go for it. Because you are using an amp per woofer, it will make adjusting amps easier.

Electrolytic, Now thats a smooth Graph, you've got it. Did you notice that excursion moved over? The peak did not suffer. Major Plus!!!

 

Okay good, do the port dimensions and tune sound good?

 

So what do you think Ranger, does this sound good?

2 chambered, 2.25 cubes per chamber with 1 slot vent per chamber (2.5" x 12.5" and 17.5" long), tuned to 40 Hz?

 

Electrolytic, notice that the vent length is red, its red because it wont fit in the box.

Easy, I always prefer one larger box to two smaller ones. The two smaller boxes will tend to be a little peaky. If its in the trunk of a car, its usually not a big problem.

It should work OK
