RE SX 6th order

[UMWDawg92 10+ year member]

ok so I wanted to try and design a 6th order and an old model sx that I sold to a friend seemed like a good sub for one. low enough qts specs and after using some calculators online I came up with, Front chamber~.6 cubes tuned to ~59.67hz and the rear chamber 1.2 cubes tuned to ~30.6 hz. I ran it through WinISD and it seemed to look pretty good within the bandpass region. I was just hoping for hoping for someone with more experiance to give me their opinion on how this looks.

what size is the sub? what style 6th order two ported sides or ported into ported. i think your tuning is low to get proper port size unless you plan on making the box a lot bigger.

Seems really small. If you are interested in a 4th order design, I can help you there.

its a 12 and the 6th order style is two ported sides. the ports can be external if they're too long too.

your gonna need a lot more size on the rear chamber like 4cu and up the tuning of the front chamber to 90 you will want about 60 sqin of port per side
