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?

Kinda like why you’re able to keep posting here.  Aren’t there some Bose drivers somewhere you need to modify?

Where there is no hazard to public health, unregulated is good. It means the customers can get what they want by forming a market for it.  A regulated business produces what the regulator wants. 
Kenjit - has a market formed around the speakers you produce?  Sounds easy, so go for it!
