Hello Vantz,
Looking closer at the photo of the powered JBL speaker, the XLR input is female (therefore, accepts a male XLR), and the XLR output is male. This is based upon zooming into the photo you provided in this thread. Assuming you wish to plug into the powered speaker, your 1/4" to XLR should be terminated in a male XLR cable, so as to be accepted by the female input XLR receptacle. By the way, that particular receptacle will also accept another 1/4" input cable.
If you have any questions, whatsoever, do call Sweetwater; they specialize in personalized service and would be glad to discuss your cable decision with you.
EDIT -- CORRECTION REQUIRED
I stand corrected; olepro is right in his subsequent response dated 09JAN2012 that the M-Audio features a line-level output rather than a 1/4" jack type output (that I had quoted from you in my original response -- without checking that the M-Audio photo you had supplied indeed only furnished line-level outputs).
Many thanks to olepro, as well.
Cheers,
Joe
