My favorite box build is experimenting with a octo and I think he has it figured out. My equipment. 2 XL m2 12s on a 5K, later I'll be going to level 5s on a 7.5 or 9 depending on electrical at the time. My question, I want to do a 6.75 inch octo, I wanted 7.5 but I dont have the width, motors wont fit. I seen that in a car like mine that pulled a 49 at the headrest on 2 level 3s off an AQ2200. I really want to get that loud! 3.05 net with a 39hz port for the meter and a 33hz add on for daily, 37.77sq with 11.74sq per cube . Subs up port center rear in a Scion tC, opinions? Will this satisfy my low end love I have now with my 31hz music box and good meter when I need it? To bad it only does a 45 sealed up peaking at 46hz with the box thats in now..

I seen a mock up. its a bit different then Im use to. Its not a true 6th order cause the subs will be firing out of the box. Basically picture two chambers, the front chamber toward the front of the car will house the drivers, up firing. There is a small port along the sides of the box going to a big chamber then firing back out a standred looking port. " You can think of it as a series tuned sixth order but with the subs mounted so they radiate externally." Its going to give me the 26-60 im looking for. They say he is one of the best we a good track record so it dont hurt to try. If not Ill use the posted sketch.

I think I know where I screwed up. Common port wall, I put 1. Well shit. Thanks CJ, I should of asked you guys before but I already got Evan in work on a series 6th order. I should have the final specs this evening and Ill share them with you guys.

I gave up and left it to Surreal at woofer warehouse. But I would still like to know what I did wrong

They where moving the same or real close to it. Port is 3.5 wide. I used Torres to get the specs and it came out to 3.6 with the double baffle.

Its 34 wide, 25 deep, 15 high. Port is 26 inches long. 45s in the corners with 1 x 4 cross braces. i thought it had 3.66 internal after displacement.

Im deff getting some excursion. Ive never seen a sub move like these are, minus the big excusion woofers like the new chinese junk XXX and W7. I think they are moving just a few mm to much though. I added .5 cubes to it last nigh to see if it would help. I dont think it made any difference at all.

And thanks everybody for the replies. If I can get this straight Ill be sending in my team app. I dont want to be on a team with a sub par set up that dont represent. I know Ill be able to walk on everybody locally.

I already have them. I just turned everything down for now so i dont break anything until a new box is done. Tuned with the -10 tone and 26hz SS they dont like it at all problem, do it with the -5 I could set it at 0 and they still bottomed out. And output was not impressive for a 5000 watt system. It was supposed to be tuned to 32hz but I guess im a tard and did something wrong. And the other question. I think its the 38hz note. The louder bass line dependent on your system, the higher or lower note? I want to say the higher note. Cause i can play "juice box" fine for the most part.

The first box I tried them in was my old level 4 box which was lacking a bit of port area. They where OK there until they started getting loose. It was only temporary.

I am just to have them continue to breakin. Gains turned down a SS is up. I think 1.5 is going to be the best bet, but would i be losing some low end authority?

Im not sure what the note is but its pretty much the heavy bass line in "Money Man"

Thats what I was going for. I dont know what happened with the box I just finished. It was supposed to be 1.8 per driver with 13in2 per cube tuned to 33 but they are bottoming out soon as I put the power down. This is box number 2 that has been fail. I used the Torres calc but I guess I did something wrong
