[esisthebestpart5]

i have 2 Havoc 15s on there way and i am building a box subs forword port up and the box is 10 cubic foot box (internal volume after all displacements) with 112 square inches of port and tune the port to 33Hz what should the leangth of the port be?

[AI James]

your box is way to damn big for one and im predicting port noise for 2

[esisthebestpart5]

i have 2 subs

[AI James]

yea 2 15s in 10 cubes net is big

i did 2 in 7 net and they slam hard

if you said they were 10 not including port and all that it may be close but 10 net no way

[esisthebestpart5]

including port i have a zx 2500 to power it

[AI James]

your first post says its internal volume after all displacements. port is a displacement. id help you with port numbers if you can give an acurate box volume and measurements of port

also you only need 3-4 cubes net each for those subs on rms power.
