What's off-stage beaming?
how about 4x10!!!!!! That rocks!
I was interested in those Avatar cabs. Now, I'm not so sure anymore.
Thanks, Jason. Why does that happen?
Rob,
One reason it happens is because the sound waves produced by each speaker interfere with each other. If you listen exactly in front of the center of a 4x12 array then all the sound waves coming in that direction are in phase which increases the volume a lot. If you listen off-axis, for example if you have a 4x12 on the floor and stand in front of it, then you can get cancellation of the waves soo the volume appears less.
"Off stage beaming" is my name for what typically happens with some people who use 4x12s. They change the volume based on what they hear off-axis on stage. The volume shooting into the audience is much higher.
Hope that helps!
Let me spin this another way as this might make more sense and better reflect what I'm wondering:
Assume you have no amp whatsoever. You get a head, and you're going to get just a single cabinet. Size and weight are not considerations. Do you go with a 1x12 or a 2x12?
use combo for smaller clubs. Buy 2x12 for bigger gigs. Just unplug combo speaker and plug only the cab. It will be just like a head version
