On the contrary, I got my start in car audio and spent years in that game before I owned my own living space where I slowly transitioned into HT vs CA.
Speakers are designed with specific applications in mind. Home theater speakers are designed with a higher impedance. For a two way monitor you usually have two drivers, both rated at some higher impedance so that once you pair them via the crossover, they end up with a nominal 4 ohm (or higher) load to your amp or receiver. Car audio components on the other hand tend to shoot for lower impedance, one that could actually end up doing very bad things your your receiver if you paired them up.
You are correct that most speaker designs are meant to have a flat response. But if you don't understand how cabinet volumes, baffle step correction, and things like that work, you have some reading to do. True, you could probably toss your kappa perfects in a PE box and think that they sound just fine, my only point is there is likely a comparable setup designed for actual home theater use that will be more refined and sound better.
I did many custom installs back in the car audio days, and I assure you, while kappa perfects are some decent speakers, you don't have to try too hard to find better options out there in the HT space.
