RE: Division of labor in PA system-More

For acoustic music no. But for electronic music-very probably yes.

To get an idea-usa an RTA (iphone app-computer download etc) and DON't turn it on.

Now play your music and set the bass level where you think it is "right" in relation to the upper freq.

Now put the RTA mic where your ears were and see how much louder the low freq are than the higher freq.

This gives you an idea of the SPL difference. NOW you have to determine how much cabinet and amp ratios it takes to make that difference.
