Default bassrace idea section

I need the help of those heavy cone area guys because i'm workin on a design in my scion tc and have a few options to go with BUT each choice is based upon install.. which will greatly effect pressure output...

this is what i have and so on...

19-21cuft NET

Power-
i will only be able to run a single 270A alt
batt up front, 6 G31s in the back. Maybe D3100s since i'm pressed for space. So, 6 D3100s.

Amp power- 21-30kw

I need to contact XS to see what my theoretical V drop will be after 30-60sec.. but i've ran worse without issues..

LAst year i ran 21kw off stock alt and 2 batts for 30-60sec for 3 months without any problems. MAX power pull was 898A on music.

OK, back to the thread-

I am staying with DC because.. well hell, they have everything i need, hehe.

I can run the following-

16 10" Lvl3s off 21,000w @32hz
12 12" Lvl4s off 28,000w @35hz
4 18" Lvl5s off 28,000w @32hz

Now onto how they would be installed-
4 18s would be traditional ported wall with port down the middle.

the 12s and 10s are built in a "Tunnel wall".
I know nothing of these, they look like they would cause massive phasing and cancelation but i know some people have built them and get loud...

For the 10s- 8 10s would be in front of the wall, and the other 8 10s would be mounted inside the port, 4 on each side.

For the 12s- 8 12s would be in front of the wall, and the other 4 12s would be mounted inside the port, 2 on each side.

I have also seen the diamond wall not ported and i know nothing of the potential for this design as well..

I am not building anything else after this.
I wanted a 160 driver but i don't think i can do this with my focus of constant output vs burp so the goal is to get the loudest sustained score i can get. I'm not really into burps.

So, what should i be doing or is there another option out there i should look into from DC?

I'm currently eye-balling the 12 12" Lvl4s as i think they have the best potential.

no, tunnel wall as follows-

So many subs mount in front of the wall.
Port down the middle.

subs are mounted onto EACH port wall inside the port.

Sounds like a huge time delay and possible phasing issue.
What kind of vehicle is this going ink

Wait you have 20 cubes?
After wood and displacement youll be cutting it close with 12 12s why not just do a clamshell?

Scion tc.

and yes, i know.. it sounds terrible doesnt it?
That's why i do not understand if it actually does work.. effectively enough in a sense i guess..

Of course i have full control over the build. If i must wire subs out of phase to get them louder.. that's easy, just see in testing if it's necessary.

I just don't ever see people talk about these types of designs.

Or, like u mentioned, the diamond...

the Diamond is another design i had looked at but diamonds i see are just a sealed wall? No port.. i don't understand how they could be loud either... I'm sure the diamond is acting like a loading area, slash, port... but it's beyond me, lol.
