Because you, and your friends said it sounded good? So yours had amazingly little cancellation. All my friends said my system sounded the best 'back in the day' too, and it was worse than yours (by brand name anyway). I guess that means mine had very little cancellation too.
When you first came here, I remember, you didn't even know the concept of multiple sized drivers having cancellation. Now you seem to think you have the topic mastered. You dont. The simple fact the the two different sub sizes had different Fs specs should tell you that they would display different frequency responses. And when you have two different drivers playing the same freq band but not displaying identical output at every freq, you will get cancellation. Some of it will be destructive, some of it constructive. IOW, some of the cancellation will diminish output at certain freqs, while at other freqs the 'cancellation' (or more specifically, interference) will boost output. That's a given. It WILL happen, no matter what your 20 highschool friends told you.
Now, multiply that erratic frequency response times the cancellation effects of the environment of your car, and things can get really messy.
One of those types of cancellation is normal, we all have cancellation going on in our vehicles thanks to reflections. But your system started with an erratic response before it even got a chance to start bouncing off your interior. What you would like us to believe is, you aligned the stars perfectly to build a system whose erratic response from mis-matched equipment was exactly offset (or almost so) by the cancellations due to your interior space. All from a highschool kid who, before we told him, had no idea what this 'cancellation' business was all about.
You surround yourself with your own bullshit, and then claim the universe is brown.
