Sub OD: 15.625”

Mounting depth: 8.000”

Displacement: 0.17cuft

 

what do you want the port tuned to?

 

oh yah forgot about that i was thinking 32 hz

 

3.4 cubes @ 32Hz...

36W x 14T x 18.5D

VW: 3"
VH: 12.5"
VL: 24"

Just a real quick one.

 

are you taking the sub displacement into account?

 

Yes I calculated for displacement. But I made a typo too, supposed to be 18.5" Depth

 

thread *****!

have you seen any positive effects with the subs firing up at an angle towards the glass....or would that just mess up the port design......just a random thought i had the other day....

 

In the 2 doors, the near 45 degree back glass does wonders with up firing designs. I havent done too much experimenting so I can say conclusively that aiming toward the glass will have negative effects, but when you get into wierd angles sometimes you start seeing more cancellation.

 

ahh, thanks for the reply

 

so these are the exact demensions i would need for my box?
