Hy guys can you help me with the dimension for a 4th order bandpass enclosure.
And what is the correct cutoff frequency, i`m thinking at 200hz?

Will need the driver specifications to go ahead.
If u want 200 hz cut off on higher side ( i assume) then the lower side cutoff will be from 80~100 hz normally.
the driver specification are in the link. but i`ll post them here to. I`m refering at the cutoff frequency for the subwoofer.

quickly to simulate and still don't see any details i post the link to download cab design. Matei Alin high freq cut off about 100-150 is better than 200 hz

The size isn`t a issue for me. And the port diameter is? Tnx (is this the best size) in bass box 6 it give me v1= 30l v2 = 27l.
What about this
