Lol. Good luck getting any help with any BP, let alone an 8th order. Since it's just an 8, I would just make some shit up and start building. Or, at the very least, try an online calculator for a starting point. Let me know how it turns out. I might try one for one of my eD 3.6's today just for shits and giggles.

you were bashing audiodave in his thread, and here I see you want to build an '8th order' which doesn't even exist.... 6th order is a dual-reflex. WinISD is great software for designing boxes, and it's free.

^, I heard that WinISD doesn't work well for bandpasses, I recommend you get a copy of bass box pro.

what do you mean 8th oeder doesnt exist? The port that comes out of the 6th goes into another chamber, which is ported to the outside.

8th order bandpass certainly does exist.

lsp cad can calculate it, if its still available anywhere. But it has a very steep learning curve. I've gotten frustrated and given up many times.

Huh. I've never heard them called '8th order', always a 'tri-port' Bose used to use them a lot way back in the day.

7th order has passive crossover added onto it, which I think is pretty stupid in a car.

tri-port is a bose patent. iirc they own the commercially available 8th order.
