Im asking this question on here because i cant seem to get fi to email me back, but im wondering before i order, is a 7 cube ported box too small for 2 btl 15s? if not, what HZ would it need to be tuned to?. i figured it might be a bit small so ill probably have to get 12's but i have never played with these subs..thanks

If you have 7 cubes after displacements (subs, port area and bracing) then I would get the 15''s and if that is before displacement then I would go with the 12"s and get ready to blow some shit up. What type of music do you listen to, how do you like your systems to sound?

i honestly listen to everything. i mostly prefer SQ type of music. i had a dd 9512 in a horn loaded box with 4K daily and sound quite nice with my mids and highs (12 pairs of jl tr 6.5s) and got real low, but got to hear my buddys btl 15s and liked them alot. thanks for the help man

Not a problem, but like I said if you dont have the space then 12"s would do better in a recommended box then 15"s in too small of a box. Good luck with choice.
