Can anybody be a speaker designer?

I have a suspicion that anybody can be a speaker designer. There is no right or wrong way to do a speaker. Tekton uses multiple tweeters whereas most only use one. Heck I could do a speaker with 100 woofers and nobody could prove me wrong.

Is speaker design the easiest profession to get into?

It requires no qualifications. It is not REGULATED. And it can potentially make you rich. Have I answered my own question?
