Wanna build box for 2 l715...need help

[Alexander Henry Freeman]

Hello newbie here was wondering if you could help me...i have a 98 expedition and 2 l715's i wanna build a ported box for them with the speakers facing up and the ports facing up....i dont want stuff getting sucked into the port....is it better 2 build 2 boxes or just 1 because i do not want them to share the same air space as far as dimensions...24-26 inches deep 40-48 in wide and 18 to 23 inches high. i would like to have the maximum airspce closest to 12 cu ft if possible. i would like to tune it to 35hz and will brace it with 2x4's unless you reccomend wooden dowels or the corner braces.if there is anything eles you need pleas let me know. any help is greatly appreciated as i am trying to avoid buyin the commercial box of of ebay

12 cubic feet sounds a little big ive seen them in about 8-9 after displacement. and also you dont need to have 2 seperate boxes or chambers they arent going to mess with each other.

i keep hearing that i dont need seperate chambers...kinda just wanted it that way....i was just going by kickers max specs....but the box i have for the 1 right now has dimensions of L=20 W=30 H=17 port about 3 inches and sounds great.....if i had a matching box id be in business...i need visual plans...these cutout sheets without a diagram that this app makes isnt working for me

shared airspace is always better.

Single chamber

10-14net

Keep the port area low

My single 15 was

7net 90sq" at 37hz and I loved it
