The clue is in your mention of RMS. Your PC speakers are rated by PMPO,
"Peak Music Power Output," and this 240W rating is for both channels
combined. Your Williamson is 15W _per_channel_, for a total of 30W RMS.
Since PMPO usually represents about 5 percent of the true RMS output, each of
your amplified PC speakers is good for about 6W RMS, for a total of about 12W
(with huge distortion at that output level). Even this rating of the PC
speakers is probably grossly exaggerated.

There are Watts, and then there are Watts.

At least, this is the case with the speakers we sell in our shop. ;>)
