Sound about right?

Alright, so I got bored and decided to try and figure out box specs for myself for a Level 5 18 and this is what I came up with.

Height - 11"

Width - 37"

Depth - 38"

Which before displacements = 7.12 ft^3

After port,sub, and brace displacement i'm right at 5.5 cubes, which was my goal (recommended by ThorsHammer)

My port specs are

Height - 2"

Width - 30.375"

Length - 16.75"

This, with my box build puts me at 35.08hz (used the Torres calc to do all of this.)

I was wondering what you guys think? Does this enclosure sound like it would fit the sub well? Would I be happy with the 35 tuning? I'm going for a daily driver, and i'll be hooking it up to a Crescendo 3k @ 1.4 ohms

EDIT: It'll be going in the trunk of a 1990 Oldsmobile Eighty Eight, with the sub facing up, and the port firing towards the cabin

Impedence rise will bring you near 2 ohms. At that impendence you'll get around 2000 watts rms. I would do an XL on 2000wrms

Level 5 is already paid for, just waiting on it to ship out.

Open to other suggestions though. I'll be maintaining a mostly stock electrical aside from Big 3 in 1/0, 1/0 between batts, and 1/0 from rear battery to amp. I'll be using a D6500 for the rear.

I'm guessing you got .7 ohm coils. Maybe you could get a dual 1.4 ohm recone and wire it to the amp at .7. It'll like that.

Or you could get a T2500-1bdCp

I would go a little more on the port height, 2" high port is likely gonna have port noise.

Any idea what i'd be paying for a recone? Because dual 1.4 is what I would like, but I couldn't pass the deal I got for the dual .7

Any recommendations on a port for the sized enclosure I chose then? Because if I change the height, then the freq of the box changes, and to adjust I end up screwing up the volume. I'm trying to keep it dead on 5.5cubes

You need to contact DC. Thorshammer responds really fast to PMs. You could call them too (idk if they're open on weekends)

Thor is the person i'm buying the sub from and he's the one that told me to shoot for 5.5 after displacement, and he said as far as freq he uses the term lab to tune, and adjusts as he finds necessary, and i'm not really that skilled, nor do I have access to a TL.

I can probably make a completely different port, I was just trying to shoot for 35 because i'd get a little more of the more audible tones. Not going for SPL. Don't care how loud it gets as long as it sounds good.

Any ideas?
