well im downloading big torrents here taking up all bandwidth so i cant view those pages but i will say that you cant go wrong with anything from Logitech.
Iv bought some 2.1 Logitech z230's and i was absolutly blown away with it when i first set it up, couldnt believe how much sound and bass that was coming from these small speakers and sub, and pretty much all the time the sound level is right down and its still booming with the explosions on games and music etc, so yeah the Logitechs come highly recommend, infact anyone with speakers from Logitech will agree with me, plus there really cheap, you simply cant go wrong chap
