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!
