[QUOTE=LTD02;59669200]i think you are already on a good track. it just comes down to dimensions that you have to work with.
allowing for the toe-in that you may wish to experiment with, and about 3 inches or so behind the screen to driver, how much depth do you have/can you make?
depending on how tall the subs end up, you may wish to raise the 4722's up a little more than a port height and fire under them. firing under the 4722's will effectively length the port somewhat, but that won't be the end of the world.
if the ports need a vertical port extension that is an option. the specific details of the port size and length will obviously depend on the cab dimensions.
how large can you go?
! That's an interesting concept putting the 4722's a bit higher!
Just from curiosity: ok, my baffle wall will be not hermetically closed, but IF it would be the case, can you fire your port behind the baffle wall?
Quick calculation: wall is 500cm wide. Deduct 3x 4722's = 500 - 229 = 271cm width left for subs = 106.7 inches, so let's take 50" width per sub.
My existing 2 subs (tuning 18hz): https://www.avsforum.com/forum/155-d...l#post55153726
I suppose B&C's and Lavoce san214.50 can be used without any adjustments.
What do you think of sketch attached: green frame = AT screen / blue = plasterboard baffle wall
I can go with:
width = 48" (MDF sheets here are 122cm or 48.03" width)
height = 40"
depth = 18" (4722 = 17.75)
I wouldnt go lower than 16hz tuning in order not to loose too much SPL higher up.
Thank you so much for your kind help!
