Light Weight Portable PC/Studio Speakers

Heloo Every one

Im to be going on my travels abroad in a couple months (Uk to NZ for a year or so) And in need of a lite weight portable pair of speakers, they don't have to have a massive volume out put, but be loud enough for use in a medium size bedroom, clarity is of the main importance, along with needing to be highly portable and 'Lite!' any recomendations on good quality PC speakers would be much appreciated

Thanks In advance
