So, I sold my friend my HSU STF-2 subwoofer, and recommended that he get M-Audio AV40 speakers because of his budget. I looked at the picture and thought I saw an output for the sub, but alas, it was and input for the music. Is there a way to hook up the sub to the speakers? If so, that'd save me the thought of having him buy speakers that won't even work with the sub 
Thanks.

Thanks.
