When loudspeakers are new they will take time to reach their full potential.
It is often debated whether any solid-state equipment, such as CD players or
transistor-based power amplifiers change with use, but the characteristics of
mechanical devices such as loudspeakers do alter and improve their performance
significantly after a short ‘running in’ period.
The science is simple; as the soft material surrounding the dome or woofer cone is
flexed it will eventually reach a point where it has optimum compliancy allowing the
drive unit to move more freely. This translates to greater accuracy and speed of
attack in the bass region and the mid and high frequency produces a far more vivid
audio picture. This short ‘running in’ period takes approximately 15 hours of
normal use.
