Need help asap!!!! Wats my box tuned to?

[BFF Larry]

Maybe u could keep the box if you don't use subs that need as much volume.

[Joe X]

yeah if it has bracing i'm guessing 25-26 range. really low...

Damn that's low , he lied and said it was 35hz. Can you tell me how cubes each sub gets and wat to cut the port down to tune it to 33 hz.

3.43 per sub and the length of the port is 7 in for a 33hz tune

Wow y only 7 that seems to short, to cut from 22.5 all the way down to 7 I would ave thought maybe like 12 to 15 or something.

Also don't dismiss that your port area is too low by a large margin, you will still have a faulty design even if you retune.

There's still a lot of port area missing, the holes are cut for 12s, etc. Would be louder if you made your own

Yea that's wat I was thinking just get some diffrebt 12"s

I mean The way the box was made you can't cut the box and open the port up some more, originally his port area was 19w 2.5h then he cut it to 4.25 in height. No if I'm correctly your supposed to have between 14 to 16 cubic ft of port depending on the cubic ft in the box, so let's say it's 6.4 per chamber so take 6.43 times 15= 96.75 per side . So total port are for this box needs to be 193.5

Then it if cut and open the port to 5.1 instead of 4.25 were it is now that puts me at 96.9 per side. Then I would cut the port down to watever it needs to be to get to 33 hz instead of 24.

You say per side, so there is two 4.25 by 19 ports? That would change a lot of things

Yes it's two ports, sorry I didn't mention that

LOL... you just happened to miss you have two ports.... you are tuned to about 34Hz then, each sub get about 2.9 cubic feet. port area 1s 161 sqin.. and everything looks much better

How is it only 2.9,,,,, 43 times 33 times 22= 31,218 diveded by 1728= 18.06 and my net would be 14.8. Divide that by 4 and u get 3.7 before displacements.

43 times 33 times 22 =31,218 divided by 1728= 18.06 times .82= 14.8 divided by 4 = 3.7
