I'm assuming you're talking about the Logitech Z560's, and if so, I would rather purchase the Altec 641s. The Altec's have a nicer sharper clarity in the sound, where as the Logitech's also have very good sound, albeit very boomy from the bass. They're both excellent sets of speakers, I'm sure you'll be happy regardless of which set you choose. Also, take the controller into consideration. Logitech's is wired, and looks cheap compared to the rest of the system, in my opinion. The Altec remote seems a bit more stylish and is wireless (correct me if I'm wrong). Just giving you some things to consider - and since the Altec's are cheaper this should be a no-brainer .
