use 1/4 plug cable for speakers?

[liquidice]

I currently use 14 gauge for all speakers, and 10 gauge for center channel. The 1/4" plug cable is 12 gauge. It just seems like a waste sitting here doing nothing, and thought I could use it for my mains. I'm pretty sure it's an audio cable, as used in a studio to run to the mixing board. At least that's what I used to use it for. And also I don't like the idea of banana plugs, I'd rather have that direct connection from speaker to receiver, nothing else conducting through anything.
