Since the op is feeding active speakers I assume he's using single ended output probably through RCA connectors or TRS to send the signal to the active monitors. Since it's single ended there would be no common mode noise rejection from twisted pair balanced wire. So wouldn't a grounded shield cable like Canare Star Quad be better for RFI noise protection? I would think RFI noise would be much more of a concern compared to high frequency signal loss to capacitance because any RFI picked up will be amplified in the active monitors. The key here is the op really isn't discussing speaker wires because he's sending the signal to the speakers to be amplified remotely. We're really discussing an interconnect cable which would benefit from a shielded cable.
dclaz, I would use the Canare Star Quad cable to feed the active monitors. For single ended common ground use I'd use the two white wires for Left +, the two blue wires for Right +, and the cable shield for the common ground Left - and Right -. This will ground the shield and give you noise protection.
This is Canare Star Quad cable but the markings are for balanced line use:
