Some questions about the Logitech Z-5500 Digital speakers

Hi,

I am thinking about buying the Logitech Z-5500 Digital speakers. I am going to be using them for watching movies and playing on my xbox. I am also thinking about using them in small party. The room is about 65 feet long and 30 feet wide. Do you think this system would be enough for a room of that size? I'll be the dj.

Thanks
