98 Tahoe 6th order build.

[T-MAN220]

Hey everyone,

I'm looking to build a 6th order box for 4 skar audio sdr-12s d4. I'm aware they are kind of  a lower end sub. I currently have 4 skar sdr12 powered by one skar rp2000.1d at .8ohms. in a standard ported box tuned to 35hz with roughly around 8cubic foot of box space including space taken for the port.

It's decently loud but I wanted to see if it's possible to get louder just by building a different type of box. If building a different box with the same subs makes no difference that's okay. I'm just wanting to try to build a more complicated box to challenge myself a little bit.

I'm not entirely new to audio stuff but I'm very uneducated on lots of topics regarding audio. I've tried doing research on 6th orders and everything I read just is so confusing. I've tried using bassbox pro (I got a pirated version of it and used it) i added the skar sdr12 to it because it wasn't already in the driver list and that was easy but everything else on there was just confusing the absolute hell out of me. I used winisd for testing my ported box (I currently have) before I built it and I understand that pretty good but I can't see how you can build a box with it like people says unless I'm missing something in the program. I've watched a dude on YouTube explaining 6th orders but he just explained how the box operates not how to build one. I understand the two different ports and one being tuned for high and the other low in a 6th order. But how do you figure out the cubic foot the box needs? Other then knowing it's a really complex box I don't know nothing about how to build a 6th order. I've looked around on here and I've fount people asking about ratios like 1:2 and 1:3 for the size of each section but how do you determine what size anything needs to be? Because the only thing I know is the recommended sealed and ported cubic foot the sub needs. Would I use that to determine anything? Just any help at all would be appreciated or any sort of form or website that simplifies 6th orders would be greatly appreciated thanks:)

Sincerely,

T-MAN
