They believe what some authoritys tell them. Even this "authoritys" are self proclaimed. The difference is maybe that 40 years ago it was much harder to create a audio magazin than today a youtube channe.
That hole in the box add some upper bass. This could work to give some bass shy 4 inch to have a little more umpff. Close it upper bass should get less.
I just like to see a little bit of fun in this drama. ;)
The only two things i learned is that 4 little holes have less influence than i have thought.
And that even some successfull people have absolutly no social behaviour.
But thats just my subjective impression others may think different.
There are possible things that make to hear the difference even harder to hear than it already is. One Hz i can only hear on headphone in direct switch. I not say i have the best ears.
If you realy had the bad luck that you have a strong 88Hz resonance. And you bring it to live with 87 Hz you could maybe hear a mix. But the driver itself can only do what it gets. So the driver plays 87Hz when it gets 87Hz.
Hehe bashing on ferrari saying "Hey whats wrong with you guys did you smoked to much? Ferrari white is blue you ######.' And they what??? Sounds like fun. ;)
