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?

Of course anyone can design a speaker.
Building it and making it work properly?  That's the 'big trick'....
Your results Will vary.

Yup, at birth.  Like the rest of us, proving that timing IS Everything...
*sigh*

I get what you’re trying to say Kenjit. There are plenty of companies out there looking to give us the “full tilt” and then send us off with their overpriced garbage. It’s a good thing we have this forum to gather and exchange useful information before parting with our hard earned cabbage. 
I guess not every thread can be a great and informative one, but there’s certainly some entertainment in the responses. 
Actually I am giving a try to a DIY pair .... so far I am not at all sure that my result will be any good, but I wanted to try anyway.
