No, they just hide their identity. You'd be shocked if you knew some of the people lurking on forums (DIYaudio specifically) for new ideas and information. Plenty of them admit to working for high end companies, just not who exactly. We've been copied by one of the biggest companies out there (as far as we can tell, appears to be the same thing and dating lines up, and no one else on the planet has ever come up with it). And more than one design from the forums has made it mainstream or become a company. People don't do nearly as much chit-chat on that forum. It's probably the richest source on the planet for designing audio information - in fact in many ways it's the only source since it includes subjectivity comments unlike textbooks on many things (we all know not every EE or physics guy could make a good sounding piece of equipment to save their life).
The Cookbook is good, but as much information as it has, you are still responsible to make the speaker sound good. Knowing what it has, will help you greatly to diagnose problems and work on design goals. However it cannot actually tell you how to make a good speaker, there's a LOT more to it, and a lot more discovery to be made with drivers, boxes, etc. If you want to just ignore everything and slap stuff together you're in for a long road. I can assure you people that designed the M2's (or any JBL), Alon Wolf, Andrew Jones, etc know about all the technical stuff there is to know. It's having the experience and wisdom to figure out how and when to use it that separates them from someone else.
We have the ability to help with technical advisement, particularly on the electrical side. We are not "by the book" so much as we are "by the sound we use the book". I didn't mean to turn this towards a plug, but I assume your really great resin boxes could use a hand in accelerating them into people buying.
