Just a different type of brace that I've never seen before. I'm Used to seeing the T type or window type of braces. I didn't realize that small of a piece would actually help brace a box. I initially thought that those pieces were for airflow, not bracing. Never too old to learn I guess. I guess that those pieces prevent the bigger panels from flexing.
There is math behind it. There's things going on inside of my boxes that people don't know about, unless you are a long time designer like me. Even long time designers that I've know, I don't see them doing it like I do. That's fine, I just have my own style, you know?
My brain has very very strong visualization abilities. Most boxes are immediately visualized in my mind before I ever start looking at numbers. I've done so many boxes, my mind just knows how it's going to lay out. People would be surprised I think at some of my boxes, and the actual math behind them. There's all sorts of tricks you can do with ports, bracing and airflow to save space and help the air actually flow through the box.
I'm not bragging, I'm just trying to explain something. Back in 2013, I had a competitor contact me and tell me he was told about me by a guy with a double PHD in audio engineering who makes speaker cabinets and other stuff, I'm sure, for really big musicians. I was 21 in 2013. I got to talk to the guy a little bit with the PHD's, and we talked about ported boxes and how awesome they are. Sometimes simplicity truly has an untouchable value. But anyways, this guy told me that, in his eyes and at the time (2013), I was the 7th best car audio designer in the world that he knew of, and the 4th best in the United States that he knew of. That's what I was told.
I say that just to say this: I just get sound and bass, in general. There's stuff I do in designs that I used to not even understand how it helped, but I still did it that way just out of a larger perception. Now I know more than ever, and I use what I've learned to perfect my skills as much as possible.
I went to a very difficult private school my whole childhood, and that private school was probably harder to graduate than many of your 4 year degrees would be. Got too sick before I could actually do college, I was accepted to every college I applied for. UT (Knoxville), Auburn, Kentucky, and Belmont. I got accepted to do computer science at UT, just was too boring, was 100% about to really enjoy audio engineering at Belmont, but I just was too sick. In school, my testing for Quantitative Analysis, I was in the top of the top for the entire state of TN. I took the SAT in 7th grade, and was 1 wrong question away from getting nationally recognized for my score. You have to be smart to even be asked to take the SAT in 7th grade.
I don't think I'm better than anyone else. I'm actually just a poor and sick person that's lucky enough, for now, to have people taking care of me.
So when you see my designs and wonder about stuff, maybe think about what I put above.
Box designing is totally an artform. Idc how much math you do, and I do a TON of math, believe me. The math is important, but the math is only worth so much, if you don't understand the nature of sound and how to apply the math. The nature of sound takes a long time to understand; there's sound at literally every level of reality. Atom->Adam->Sun, all filled with sounds.
