We have to see the speakers to even being to guess at their low end performance.

Most PA systems are large and can produce bass, however if this is not a sealed box, or even ported box and what you have is an open baffle dynamic loudspeaker system then you may lack bass. However this would be my favorite kind of PA speaker as box colorations are reduced.

Remember, PA systems not only can be higher distortion (which you probably will not notice at your age) but they can less accurate and more colored as they are designed for efficiency not accuracy.

Shotgun verses sniper rifle.

The shotgun being the PA system.
