Training Tips
Do You Know About Directivity?
By Clay Wade, Assistant Global Product Line Manager

Ever wonder why no one bats an eye when a subwoofer is not pointed directly at the listening position? Meanwhile, if an audiophile were to see left and right speakers pointed at the wall instead of the sweet spot, there wouldn’t be enough sleepy time tea in the world to calm them down (ourselves included). To what phenomenon do we ascribe this strange situation?
Directivity
Simply put, “directivity” is a term used to describe the directional behavior of sound waves as they are emitted by a source. It turns out that frequency and directivity are directly correlated, meaning low frequencies tend to travel outward in all directions (less directivity), and high frequencies tend to be more focused in one general direction (high directivity).


In what may seem like a paradox, high frequencies need a bit more guidance than their low frequency counterparts, as they can be a bit too directional at times. For a next-level education on how JBL guides high-frequency sound waves using its trademark HDI™ Waveguide technology, try the the JBL HDI™ Series training course. This is yet another opportunity to learn from some of the most skilled audio scientists in the world.
