So I got a box made yesterday....

I got a box made by a local shop yesterday for my 2 12" alpine type rs....

I told the guy 4.4 cubes @ 35hz.

When they said my car was done, he told me he did the box at 40hz. -_-

They were closing so I didn't have time to conversate to him about why he didn't do the specs I told him to.

Would my best bet be to go up there to the shop tomorrow? Or will the 5 hz not be worth the hassell?

5hz is a pretty big difference.

Yo man, the cocksuckers told me that my Sundown audio amp couldn't do 1 ohm. -_-

That shoulda been a red flag right there.

Like what if the ***** says he won't rebuild the box?

5hz is defintely worth the hassle... You could try polyfill as without building you a new box, changing tuning doing down can't really be done. To lower tuning you have to have a longer port, adding wood is hard lol. However, if you add polyfill, the box will appear to be bigger to the sub, so the tuning will drop since port length stayed the same. My suggestion is to just add some polyfill. How tall is your port and how wide? If you tell me that I can give you a very good estimation of how it will come out by adding polyfill.

What exactly is polyfill?

I don't know ANYTHING when it comes to boxes and such?

Lert's say the guy DOES "rebuild" the box.... how do I know this ***** won't give me the SAME box I previously had????

Dont bother he f'ed up your box and decided to do what he wanted. The builder is responsible, have him either build another or refund. You could also try to talk to the owner about it.

Just take note of the box dimensions especially the ports length

And you can just make a few cuts/scratches inside of the boxes in a few places.

write something on the inside of the box and youll know if you get the same exact box.

 

[Radrick Davis 10+ year member]

I was thinking about doing that...

Like I said I don't know ANYTHING about boxes lol..

What EXACTLY do I need to measure?

I appreciate all the help though... this **** had me mad man smh

 

[T3mpest 10+ year member]

to do what i asked, measure the inside height and width of the port. The hole in the box, how wide and how tall...

 

[Radrick Davis 10+ year member]

How do I make sure the hz is 35?

 

[Jaredturp 10+ year member]

That ***** man. I would make an issue of it.

Well to check your tuning, for now, dowload tests tone on the internet. 30, 31, 32... all the way to 45 if you can. Then play each one at moderate volume to get the speaker moving start at 45 and work down. At some point the cone will begin to barely move, the frequecy the cone moves least is your tuning. Below that note you'll notice the cone moves alot more.

Also I graphed teh box you got and the box you want, the box you want is way better. The one you got is really peaky and has **** for lowend. Your getting an extra 2dbs around fourty hz or so, but giving up 6dbs from 30-35hz or, it looks pretty bad man lol. I think polyfill can honestly about fix this, I just need port dimensions. However, if you feel ripped off you can always ask for another box, I'm just trying to help in case that doesn't work. Like I said, tell me how big the rectangular hole in the box is, both height and width and I can help you.
