hearing stereo in live performance (was Powered Subs)

["Qua Veda" <qua@oregon.com>]

I agree, and am a proponent of stereo (or even surround) sound
reinforcement.  I would aim to achieve the best quality stereo sound for 
the
listeners that I could afford - despite the fact that whether they can hear
the separation is highly determined by room acoustics, and where the
listeners are within the room.  The room can cause all kinds of image
smearing, amplitude changes (nodes), etc.

....In live apps, one may not be able to hear let's 15hz, but 
you can sure feel it.  I would agree the feeling is probably not 
directional, but if I rise above to 100hz. I can tell the direction.  I 
don't how any anyone could say not....wouldn't that imply that if if a 
guitarist striks he low E string, listeners could not tell the source, 
left 
or right? That seems absurd.
