They will crush it alright, probably all the way to the bankruptcy receiver!
In my opinion, it is long passed time you designed and built your own speakers. What's keeping you? Yes, it is a heavy lift, but you will learn a lot and be glad you did.
Everyday, I count myself so fortunate to have never had to go speaker shopping! You seem prime to make good progress. I know I enjoy speakers of a quality I could never afford if I had not designed and built them. Even then, I'm not sure they are even out there. They are very much personalized to their space and provide the presentation and perspective that I like. More members here should take the plunge. It is an arduous, but rewarding process.
