Well ... we had a simple solution.

Some Fi's, in a manufacturer's rec. box.

But people decided to get complicated...

I think SQ and SPL are terms that are used very loosely. My goals are to represent the recording as is with little coloration. Majority of subs will not come close to this because of the huge cabin gan. In that sense you must EQ or design according to a response curve. How many people have ever used T/s parameters when designing their box? Buying a speaker and throwing it in a random box isn't SPL or SQ. At least try to figure out what the branded company suggests and shoot for that.
O RLY?

Flat sound is an arbitrary goal no one really wants.

I did that before I quickly slapped together a box for my 18. It'll move the box up and down with a 60 amp fuse in the line

Its more complicated than how you make it sound.

Each car has a different cabin gain "curve" and each different subwoofer position has a different cabin gain "curve" and each different listening position has a different cabin gain "curve"...

Kinda pointless to some extent trying to please everyone when the speakers are so damn close to everyone.

This is why... sealed subs generally result in a flat sound "curve" in cars and ported subs generally peak like mad.
