Regarding the several recommendations that have been made for Clear Day: Assuming the goal is for the cable to behave in as neutral/accurate a manner as possible, and given the 12 foot length you require in one channel, I would caution against using anything less than the double shotgun version.
For example, the single (two conductor) configuration is described as consisting of a single pair of 24 gauge silver conductors. In a 12 foot length, and given the 8 ohm nominal impedance of your speakers, the resistance of that cable would reduce the effective damping factor of your amplifier from its specified value of greater than 1000 to about 14.
