WinISD - Can you interpret my graph?

[Omarvelous 10+ year member]

Alright, i have the 2004 12" xxx parameters.

The box is 2.4 ft3 with freq of 30.

2 3" ports , each 18" long.

I put 1500 watts at 1 ohm in the signal section.

This is the graph i get, the numbers in the upper 2 boxes are at the peak of the curve

Is that the max SPL in db that i can achieve in this box?

Is this good for a 12 XXX??

Gimme what ya got!

Thanks in advance!!

That is absolutely the highest you will ever get unless there are other factors winISD didn't account for which I seriously doubt......

If you couldn't detect the sarcasm winISD is basically crap for anything other than determining port dimensions and maybe sometimes comparing boxes. There are about 9 million factors (give or take a few) that influence how loud your sub will get. So, I suppose that graph could be exactly correct but I somehow seriously doubt it. Only way to really know how loud you will get is to get your setup metered.

lol, ****.

From what i had read thought people actually used this program for more then that.

I suppose ur right, considering there are a lot of factors.

Will try to get it metered, once it's up.
