.....So I was listening to a CD the other night and I heard a little rattle, I go turn the CD player up a little bit and it turns out I've blown out another pair of speakers. @#$#@$@

.
I plug a pair of CREATIVE (I figured I would buy a name-brand speaker after I blew out my last ones) computer speakers into a portable CD player. I don't play it particularly loud, but for some reason after a year, maybe a year and a half my speakers keep blowing out. Is there a better alternative? or a better brand? .....I always get the computer speakers with the woofer, so that I can have full control of the bass, (as opposed to book shelf speakers).
I would like not to spend money on a pre-amp. Any suggestions?
