Reply to Best way to connect my powered PAs to my Mixtrack pro?

Mixtrack Pro only has 2 sets of RCAs. My speakers (Eurolives b215d) has a 1/4" and XLR inputs

I've been using an RCA cable to plug into one of these http://www.fullcompass.com/product/376833.html

However that adapter is super flimsy. I was also believe of using an XLR to connect from one speaker to the other.

Thoughts?
