Moving Air SPL

[Liam Wald]

Usually I am standing pretty close to my amp so I never get the full effect of SPL when I am playing.
Yesterday at rehearsal I walked about 10 feet away from the front of my amp and was astounded by how much air it moves.
I was using a single Avatar B153 cab powered by a Mesa M6.
The M6 master was set at about 10 o'clock position with the gain at about 2 o'clock.
I could strongly feel the notes on my legs. When I looked down, my pant legs were actually fluttering like I was standing in the wind!

That's cool. Try standing 20' out and see what ya get.

When you're standing close to the cabinet, your ears are not hearing the cab, because they're several feet above the speakers.

Several feet away, the sound dispersion allows sound to reach your ears.

Fluttering pants are nice, but they're not where your ears are!

Now that is funny (and true)! That is sig material right there!

Mid range is very important to perceived hearing of low tones from a bass.
Standing too close the mid-range beams past you.
Farther out you can hear it.
Tilt the cabinet at your ears, or raise it up so the mids hit your ears while closer.
It makes all the different in the world.

+1. Sure beats standing on your head.
