In all honesty: v=w*x*a1/a2*(w^2/wport^2-1). Then mach=v/c, where c=wavelength*frequency or 344.41m/s. To be honest, it gets much more complicated. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif where w=p/4/Pi/rad^2 and wport=sqrt(kport/m2 where kport=(1.4*a2^2*patm)/vbox where patm=101.3e3*Pa(pascals). Etc,etc,etc. Not something to explain in a text or two.

You know i would be able to under stand this if you told me what each varible ment.

That is the key right there. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif it can be simplified once it is understood. Any formula can be taught, just takes time and effort and more importantly, understanding. And that usually comes at a cost now days, lol.

 

[brodeisel 10+ year member]

yeah it does. Shoot i think i could figure out some of the variables but not all of them.

 

[brodeisel 10+ year member]

but math can be so much fun

WTF is port velocity?
You nerds need to put down the pocket protectors and slide rules and put some sawdust on the floor.

Haha nice. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I can't send you a PM now...says its full. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif my email is mobileenclosures@gmail if you wanna talk about what we were talking about.

As to the OP, I wish I could be more help to you right now, but the best I can tell you, is if you figure for it, the m/s limit is about 25-30 at lowest impedance of the design. That's all I can say about it as it is very complex to understand fully.

Easiest way- download win isd, play around with different boxes and woofers, on the vents tab it will display port mach aka port velocity.
