Peaky box?

[Nikitaaa]

Okay boys and girls, I have a couple questions.

First, my box for my single 18 is around 6^3 tuned to 36.5 with 15.5 of port per 1^3.

My box is REALLY peaky. Like.. Beyond peaky.

Lows pretty much are non existent.

1) will inverting my sub flatten out the response a bit and help it play a bit lower?

2) if I add about .75 peice of mdf to the side of the port, it would drop my port area to about 13 and tuning to about 34ish. Is this worth makin my box look weird? Will it help flatten the response?

Anyways, this box is like 2db louder at 42hz than 40hz. It's that bad.

edit* just read yr sig , yeah it might be too much port area on yr current box , test with a lil bit less . . .

From my tests 99% of the time a peaky box comes from low power I have seen it 100 times adding power (watts) takes the peakness away

So you can ether change the box or add power to fix

He has a PSI recone... on a sonic sound lab.

Lower port area and tuned lower should help with the lack of lows at high volume.

A new bigger box is needed i assume with the PSI recone.

Inverting the sub won't really help, but try and see for yourself.

Team bassick, you can't play LOUD all the time so he should better fix the box. Because if he says that the box is peaky, then it must be really peaky.

Btw, you won't hear a 2db difference.

I would try building a 2:1 4th and take down my back seats if I knew the fs and qts of the sub.. But psi told me theat they couldn't tell me..

Are you all saying I should build a bigger box?

The only problem with that is I dont have any more room in my hatch then the box I currently have(with back seats up)

Never seen a box act "peaky" at low volumes???????

Only at near or full tilt

was that sarcasm or what?

I said myself that lower port area will help at higher volume, but not as much at low volume.

Yes, higher volume can make it sound less peaky.( most of the time it sounds lower with more power.)

EDIT: Nevermind, Team bassick , i can't seem to express myself correctly.

no sarcasim at all im not following you..

all peaky boxes are peaky at or near full tilt at half deck volume or lower there is no peakness

are you talking about your changes that you suggested on the box? i am not, im talking about peaky boxes in genral

[Sanitarium]

shrink the port some usually does the trick for me.

Dimensions of my box are; 17.25h, 41w, and 24d. Port is 15.75h, 6w, and 20.75L. Double baffle with like .2 of bracing and .28 sub displacement..

If anybody could do something with winisd to show my why my box is peaky it would be great!
