Like most speakers, if they are decently made they should not blow up unless you overdrive them. I did once have some logitech speakers and found them flimsy, and that to be the case for most medium priced computer speakers. But I think the newer ones are probably better made than they used to be. The quality studio moniters are nearly always very solidly built as they are aimed at musicians, and that is good if you might ever move them to do a gig or a party. For the money, Maudio BX5s are hard to beat, but as I said, its all in the ear of the listener and opinions vary. I finally opted for the 4 inch because the sound quality did not drop off much, they were much cheaper, just as well built, and smaller and less obtrusive for home use.
One thing with many speaker systems - especially computer speakers- is to not be seduced by high wattage specs. The perceived volume produced by speakers is not always lined up with wattage specs. You have to hear them.
