Running In - PMC twotwo.5 User Manual

Running-In
When brand new, PMC loudspeakers will take a short period of use before they
reach their full potential.
This is because the mechanical and acoustical characteristics of the bass
driver and tweeter alter slightly after manufacture as the flexible elements in
their construction relax and reach their optimum compliancy. The
parameters are critically designed to load the bass driver accurately only when
it has reached its long-term, optimal compliancy.
Consequently, during the initial running-in period of about 20 hours, the
performance of the twotwo series active monitor will change and improve. You
will notice the bass tonality becoming fuller, more accurate and neutral, and
the bass extension will increase significantly. As the tweeter relaxes the treble
tonality also sweetens and integrates perfectly with the bass unit, and the sound
staging improves.
