Someone helped come up with this 6th order bandpass for 2 eclipse TI's 12's sw9122(tc 3hp) Its tunes at 30hz and 70hz. Supposed to be flat response due to the CRX peaking right in between those tunings. I know ported and sealed. Not to sure on the actual functions of BP's. Hopefull Bill or someone will give some good info on this.. thanks, Joe.
Its going in a CRX, I know subs up/port back is best, but this is close. :)

stick to 4th order if your gonna do bandpass. much easier and less costly than trying to warranty subs that are torn apart at the surround

I would advise sitting down and plunking the numbers into winISD yourself and having a look at it.
If its a good design you will know quickly. However the 6th order bandpasses dont come easy. The subs have to be rather apt to a ported box usually.

While it is a very nice looking design... I have to agree that it would be a shame to tear those nice Eclipse subs to shreds. A 4th order may still be better suited for you.

4th order is no more forgiving then sixth order which is a common misconception especially if the subs are designed for a ported enclosure. like we spoke bandpass's work on proportions and if the proportions are incorrect one way or another your subs will literally shred.

Thats the reason I've always stuck with ported. This was a design from one on the new box builders over one ROE :) I never put to much faith in the design, thats why I asked over here. He's doing folded and tapped horn designs for everyone, and most are noobs so there believeing whatever they say. I already run them in a CRX style enclosure ported with great results. I was bored, wanted to build something, so gave him a shot. I think its funny now, this is who everyone is referring to to design boxes.. .oh well.. at least it looks cool in sketchup :)
