did u saw the performance of the speakers yourself??

ideally logitech is known for making subwoofers with deep bass(thats one of the reason logitech speakers are successful)

i've read several reviews on this speaker set and they all recommended this set and it sounds odd that its not performing better than creative 5200...

i wud recommend to check the settings of the soundcard, maybe he's using the equalizer and has set the low frequency(bass) to very low level or maybe he has turned down the volume level of bass from the speakers

you can also try to run these speakers on any other computer...

one cannot rule out the possibility of speakers being faulty...so make sure how they perform on any other computer...also try to watch dvds in 5.1 mode and check how's the performance

ENjoy...
