These speakers are rated to produce between 30 and 50 watts RMS. In the
past, RMS (root mean square) was used to determine audio power output.  Some
manufacturers have gone to using PMPO (Peak Music Power Output), whatever
that is!?!  RMS wasn't perfect, but at least it was consistent, PMPO doesn't
really mean anything.  Caveat Emptor, PMPO seems to smack of advertising
hype - If it sounds too good to be true, it probably is.  Having got that
off my chest - PMPO "true wattage" (RMS) can be generally determined by
dividing by 10.

>Is there any way to check whether the speakers are producing sound at 300w?

No, PMPO is not a standard, the manufacturer decides what PMPO "means" and
what "wattage" to put on the box.  Divide by ten and you've got an
approximation of true RMS wattage.

Take Care,
