Sub Cable Through Walls... RG6 or RG59 or other?

I'm running sub cable through the walls in a new construction. I talked to Monoprice and they recommended "High-quality Coaxial Audio/Video RCA CL2 Rated Cable - RG6/U 75ohm (for S/PDIF, Digital Coax, Subwoofer & Composite Video)". My local audio guys use RG59. I decided to order the Monoprice recommended cable. I'm just wondering if I need to change course... your thoughts and recommendations would be appreciated. Thanks!

Thanks! The type I purchased for the subwoofer is all copper... according to the product description, " 99.999% pure oxygen-free copper conductor" and "This cable allows jitter-free transfer of digital audio signals. The low-loss cable design includes a pure copper center conductor and shielding to preserve signal strength and minimize noise. Gold-plated RCA connectors and pins provide solid corrosion-free contact." However, it's only double shielded, "High-density double shielding for maximum rejection of EMI and RFI"... http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10236&cs_id=1023603&p_id=2684&seq=1&format=2#description So, how important is quad versus double shielded?
