Nitpick: often we refer to &quot;omnidirectional&quot; bass because, given that subwoofers are usually much smaller than bass wavelengths (around 16 ft at 60 Hz), they have an omnidirectional radiating pattern.<p>Live sound is usually highly artifical, with the heavy use of compression, EQ, effects, and a very exagerrated bass. For instance, all reverb is usually digital, because instruments and singers have to be close-miked to avoid feedback. Also, past a certain venue size, it&#x27;s better to mike guitar amplifiers rather than make them louder or add more of them, since their radiation pattern gets very narrow at high frequencies, resulting in a &quot;pick to the forehead&quot; effect for the people standing directly on-axis and a muffled sound for the rest of the audience.
