Changing to a 4th order? Truth vs myths? Help

Thank you. Getting there. Sorry for the small hi-jack.

4th orders aren't as tough as people make them out to be. And modeling them in WinISD is honestly pretty futile. Everything changes once placed into a vehicle.

SI 18s, that's not really fair. Just so people know those subs have an fs of 17hz, which is why he can crush 17-60hz. Not many people are running home theater subs in cars. Amazing subs though, I almost got an HT 15 for my tiny apartment just because of how awesome they are, fs of 17hz with 22mm xmax for less than $200. Hard sub to pass up, but they do need pretty large boxes, and I'm not sure my downstairs neighbors would enjoy 17hz rattling the entire building.

Not fair? How is it not fair? Anyone can purchase them.

And having an fs of 17hz is not what makes me able to play to 17hz. Enclosure design. There are people with subs that have an fs in the 30's who can play single digits.

Completely "fair", but quite an unconventional choice for car audio. Those are some extreme low end monsters, designed to play T-rex footsteps and space shuttle launches. Cool to see them in a car, do you have a build thread?
