No, not with the version that has a speaker amp in it. Return it and buy this one if you want to use powered speakers.

Also, the R-51PM's are pretty awful speakers. The Neumi BS5P's are better and they cost like $100 less.

Or better yet, keep the version of that Dynasty kit you currently have, and get some Emotiva B1+ speakers to use with it.
