Raising or tilting a cab is a perfectly sensible way of hearing yourself better. If you raise more than a couple of feet though, you'll lose volume because of a lack of boundary reinforcement from the floor surface reflections (or something )

This from Bill Fitzmaurice and I hope he won't mind that I pinched it from another thread about cab-tilting:
[color=#282828][font=helvetica, arial, sans-serif]"The picture below shows +/- 30 degree dispersion, which is about average in the upper mids from a bass cab. In the upper frame the cab flat on the floor puts the audience within the dispersion pattern, but not the player. In the lower frame with the cab tilted both the audience and player are within the dispersion pattern.[/font][/color]

[color=#282828][font=helvetica, arial, sans-serif]The issue with lifting the cab is that if you lift a small cab high enough off the floor to hear the mids at close range you will lose boundary reinforcement in the midbass. That can be beneficial, if the room is boomy, as that will reduce the output in the boom frequencies. But in a dead room you may not want that reduction in the midbass. If you want to be ready for any contingency have the ability to either tilt or lift the cab to suit the room."[/font][/color]
