If by manufacturing you are referring to grabbing some off the shelf parts somewhere in Asia based on what is available and assembling them, then that is a really weird definition. All the real manufacturers of course use T/S and modelling everyday. Exactly how criteria for product development occurs. If you want to go to Harman, Seas, Scan Speak and so on and tell them they are idiots and you know more by seeing a woofer, go ahead. They'll laugh their ass off at you.
Since you have the great idea of showing how modelling doesn't work and own an RTA and a company that sells things perhaps it should be you to prove the rest of the audio world is wrong. This is how the thread derailed as you call it. You told someone to do exactly the opposite of what the educated audio world does. I'd like to see how this arbitrary process of yours works.
You seem to know an aweful lot about my company for knowing nothing about me, or my company. I wasn't aware tooling my own parts was "off the shelf". Well, I guess they were on a shelf at some point. What if I told you I used the same parts as Scan Speak? Would their parts sound better? Who said anything about T/S parameters? You're right, they do use those, so do I. Know what I use them for? Understanding the speaker, not the BS modeling puts out. You're also talking about mids, NOT subs. Mids are a very different ballgame, and holy shit I designed a set of those too. You aren't dealing with cabin changes with mids. Your environment doesn't change with output like with subs. I guess if you never get over 120 dB you might get a vague idea of what's going on.
So you're saying you can't prove me wrong? What the rest of the educated audio world does is do what the manufacturer says, because they know their product best (or should). The rest of the world doesn't build sealed boxes with an alleged 0.707 Qtc, check vehicle response out of the vehicle then in the vehicle at various SPL levels, then graph that data for trends to in turn plug that data into a software simulation to change the box to plot a graph that will make them visually pleased.
I've NEVER had a customer take my box recommendation then come back and go "ya know, it sounds like there is a 1 dB saddle around 47 hz". I'm not sure if you've got rose colored glasses or beer goggles, but you have a very skewed idea of what manufacturers really do behind closed doors. You're making everything out to be way more than it is, which based on how you're acting also tells me there is a very good possibility you either have or do compete in SQ.
