Pc speakers creative t40 or logitech z4

ok, i have a very small room. 2.4m by 3.7m. i have my pc in the corner. I need some pc speakers, as my 6.1 system won't fit. so im looking for some speakers. I will be using them for music and films. I'm at univeristy, so i cant make much noise, though i would love too. I duno what to get, the z4s look good, alright an all round system, i listened to them at a mates place, and they didnt sound any good compared to my sony 6.1 home cinema system. But reviews are saying the t40's are good, just lack a bit of bass. so i duno.
