i would like some advice on how to build a t line box. will a box for these 2 subs work in 9.9 cubic feet of space. i know the port needs to be 9.25 feet long and a constant 346 sq inch. i have a max of 14.5 cubic feet to work with but would like to only use 10 cubic feet or less. thanks for the assistance.

T lines are one of the few I have not tried, I would like to understand how these work as well!

If it needs to be 9.25 and with 342 sq in of port... thats a box that needs to be 22 cu ft BEFORE any wood displacement...

as far as I know, (simple) Tline's are only one big port
port area would be woofer sd
port lenght would be a quarter wave lenght of the tuning freq.

Your port area is way to large. On a T-line you want the port area to be the same as the Sd of both subs combined. As long as you are not using a L5 or L7 you will only need 140-160 square inches of port.
