Why do I get the feeling that the OP doesn't really want to learn anything, and only wants to argue, or try to prove he's the smartest guy in the room?
"If you dont believe in acoustic silence and only trust what you are hearing , stop reading my post and keep enjoy in bass performance open baffle design . "
Well, of course I only trust what I am hearing. What else would I trust? Some link you posted that I'm not going to read? I'm not even sure what that means.
So.....you asked a question on why OB speaker designs became popular.
You received well over a dozen replies from real-world listeners, people with real-world experience.
And you want to argue (in broken English, mind you...) that they don't sound good? That they're bass-shy? Why don't you try a pair for yourself and then get back to us.
Thanks, and have a great day.
