I'm sure that @jaxs' shop has tremendous acoustics, but I don't know if he wants to sink a couple of grand into wiring the speakers...I think you need speaker wire specifically for the best results.
Most low cost wire marketed as speaker wire is pretty light weight, and not really up to the task of longer runs due to the resistance in the wire. It would work, but not well. As audio signals are basically DC, and travel almost exclusively in the copper, not the surface of the copper, so lots of strands only buys you flexibility and resistance to fatigue from repetitive flexing (think elevator power and control cables). Go for the really pricey "oxygen free copper speaker wire" if you like paying extra for no practical advantage. "Oxygen free copper" has conductivity and impedance virtually identical to normal copper. Of course, it does make for bragging rights in certain crowds...
I would strongly discourage the use of copper clad aluminum (CCA). It is an inferior product, fragile, prone to mid-circuit breaks from bending, corrosion at the terminations, and higher resistance. If you do use CCA, I would recommend the use of Noalox, or similar products on all the connections.
Speakers are very low impedance, so having straight runs of low resistance wire will make for better sound quality. Romex, stranded, all work well.
All the best,
