4th order Bandpass Questions

[EricM9104]

Hello,

been out of the game for quite some time, started digging into the rabbit hole of bandpass just for the fun of it, and reading into the specs of my sub it's more tailored for a sealed enclosure of 4th order BP it seems... I found this calculator and input my sub parameters and box dimensions, how does this look? Sub is a Power Acoustik GW3-12 D2 going into a GMC Yukon.

EDIT: I goofed on the screenshot, somehow the enclosure calculator I was using lost what I was working on last night, will re-upload once I fix it

Alright, ended up finding WinISD (TY Google, forgot about this one!), done some messing around with it, not sure if/how I'm looking at it correctly, but I was able to come up with the following... This is going to be geared for music obviously...

1.25ft^ for the rear/sealed chamber, 2.5ft^ for front/ported chamber @ 44hz. Ports will be 2 4" aeros at 11.1" long each, uploading a screenshot/video of the proposed frequency response and the T/S specs for the sub.

Imagine if that was the actual frequency response, you would only be able to hear like 40-48Hz and little to nothing above and below that.

Thank you,

Had a feeling that was gonna be the case, back to the drawing board.
