You can check with Bob Heil, but, I have had a very nice experiences with the ICM series (see link). I also LOVE the GM gold line dual element. I'm not sure if its computable out of the box.
Drop Bob an Email or give Donna at Heil a call (618) 257-3000. She will give you the scoop on the best bang for the buck etc.http://www.heilsound.com/amateur/products/icm/
Info on your specific rig.
