Running-In
When brand new, PMC monitors 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 alter
slightly after manufacture as the flexible surround elements relax and reach their
optimum compliancy. Once run-in, the compliance remains stable and consistent
and the
TM
cabinet parameters are critically designed to load the bass driver
accurately only when it has reached this long-term, optimal compliancy.
Consequently, during the initial running-in period of about 50 hours, the performance
of the
twotwo
active subwoofers will change and improve. You will notice the bass
tonality becoming fuller, more accurate and neutral, and the bass extension will
increase significantly.
