At lower frequencies acoustic waves become more omni-directional, which means it gets more difficult to pinpoint its source. It does not necessarily mean that it radiates in all direction from the source.

In a home audio system a single sub-woofer cabinet will perform well because of the onmi-directional nature of the bass frequencies. The more uni-directional nature of the higher frequencies require two sources interacting through constructive/destructive interference to provide imaging and sound-staging that stereo reproduction is designed to create .
