Review on Monoprice Nimbus Series 12 Gauge AWG 2 Conductor CMP-Rated Speaker Wire/Cable - 250ft UL Plenum Rated, 100% Pure Bare Copper with Color Coded Conductors: High-Quality Audio Solution for Professionals by George Johnson

2 core cable for 12 gauge Nimbus Series 12 loudspeakers are designed for plenum use (for use in walls and ceilings). I bought a 250ft roll. The cable is very rigid and intended for permanent installation in walls and/or attics. I installed mine with a low voltage pass-through wall plate and hit a very stiff wire with the screw-in banana plugs. Great price, reliable connection. Works perfectly!
