<< What kinda speaker should i get for turtle beach sound card? >>
To realy answer this one, it would help to know your budget and what you plan on using the speakers for. Examples would be gaming, mp3's, DVD's etc.
<< What does 2.1, 3.1, 5.1 speaker system mean? Thanks >>
Don't you mean 2.1, 4.1 and 5.1? Although I've seen 3.1 setups, I have never heard of them being used for computer speakers. Anyway, the first number either 2, 3, 4, or 5 is the number of speakers in the setup. The .1 is simply a designation for the powered sub.
