Does anyone know of a good pair of surround speakers for my UMBP?

[djvic87]

I been having Creative surround speakers for about 7 years and the speakers are about to die. The subwoofer is already cranking. I was wondering, are there a set of speakers that are good enough for my UMBP? Is there a speaker set that can use 5 speakers with the subwoofer for the UMBP?
