You remind me of myself
It's even in my yearbook that I wanted to be a "sound engineer". Well, I'm an engineer now, but not a sound engineer. At least not for money.
Do this (ignore me if you will, but I really have walked in your shoes, and it feels like yesterday
Buy a really good kit, or build a really good design with a knowledgable designer who is open to email questions. What makes it good, we can talk about that later.
Ok, now email the designer and ask them how they designed it. Maybe share a photo of your build with them. Tell them your plan to be a designer for Cerwin Vega.
Once you've built it, listen for a long time. Like 6months. And also go to stores, friends, etc and listen to speakers. Buy a microphone and download REW or holmimpulse. Measure the speaker's on axis frequency response. Email this to the designer and ask them if you've done it right. Read the above mentioned books.
Repeat two or three more times with different speakers. Pick very different speakers and designers.
That should take you a couple years or so. Once you've done that, get into university and pursue your dream. You will very likely come to the realization I did, that there's no money in it and steer the ship. But let me tell you, that's ok. I changed engineering ideas at least 4 times, and I enjoy what I do. Now "sound engineering" is my hobby. And it's a good one.
While in university, buy some different drivers and start designing speakers. Measure and play. Make some really bad ones. If you don't, they'll always only sound ok. Make sure they really suck. Then make some really good ones.
You'll go from there.
EDIT TO ADD - I believe Curt Cambell, the designer of the statements has an open email. Wayne Parham does. Bill Waslo is ok at answering emails. Jeff Bagby is pretty good. I'm not good, but I answer emails. MTG90 does as well and he's good. David Lee Ralph has some older designs that are ok. Pete Schumacher (spelling) probably does. Mark K might. Paul Carmondy does, but most of his designs are fairly basic and small, not your style. There's others I'm sure.
