Im building a box for 2 10s today, gonna be 3.5 tuned to 38hz. Im trying to make my final decisions on where the subs will be placed. Ive got a box planned out for subs back/port back but that requires me to use/waste almost a whole sheet of MDF, which i wanted to squeeze 2 boxes out of (this box and a small sealed 2 12" box) Heres a pic of my current design that i have planned out.

Do you guys think i should do subs up ports back? Or should i keep this design? Going in a huge trunk car. Ive noticed from my tests that sealed or slot ported facing back is generally the loudest, and theres a little diff when i face them up. Im thinking of just sticking with this design unless theres a reason i shouldnt

thats a big box for a pair of 10's, especially common chamber.

none the less, subs back sounds good to me.

all cars are different, but face them back toward the trunk lid.

the subs call for 1.5 each ported, so i gave the gross volume 3.5 to account for port and sub displacement. You guys think i should make it smaller?

Just redesigned it. So now outta the 1 sheet of MDF im gonna get the ported 10 box to my measurements, and a 3 cube single 15" box. Gonna pick the wood/pvc up tommorow and build them then. :)
