What one does hear is an all-important midrange that is lucid and lifelike, with the effortless transition to high frequencies and bass that provides an eerie simulacrum of real low-frequency energy, albeit within the volume of a nutshell.

Did You Know?
It's easy enough to shed some light on the origins of lucid: it derives—via the Latin adjective lucidus, meaning "shining"—from the Latin verb lucēre, meaning "to shine."
Lucid has been used by English speakers since at least the late 16th century.
Originally, it meant merely "filled with light" or "shining," but it has since developed extended senses describing someone whose mind is clear or something with a clear meaning.
Other shining examples of lucēre descendants include translucent, lucent ("glowing"), and the somewhat rarer relucent ("reflecting light" or "shining").
Even the word light itself derives from the same ancient word that led to lucēre.
