Is a 4th order wall usually louder than a ported wall?

I read that each order is supposed to gain three db. I may have heard it from my extreme car guys. Either way that is what I have read or been told.

Also saying a fourth has a larger bandwidth is laughable. Plot one out and look. They are louder so the wide bandwidth is perceived not true. It's like saying ported has a wider bandwidth than sealed. It just isn't true.

Would that account that a vented enclosure is still a 4th order? Just not a bandpass.

Edit: for the 3 db gains

Krakin, are you some sort of mad scientist?

I would have replied earlier, but I was measuring the output of my amp with a yardstick . . .

What you hear is not the air pressure variation in itself

but what has drawn your attention

in the two streams of superimposed air pressure variations at your eardrums

An acoustic event has dimensions of Time, Tone, Loudness and Space

Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears,

thus no formula can achieve a definite effect for every listener.
