Review on Voltive 12/4 Speaker Wire - 12 AWG/Gauge 4-Conductor - UL Listed In-Wall/Outdoor/In-Ground Rated - Oxygen-Free Copper (OFC) - 100ft Spool - Black by Brett Morrison

High quality solid copper wire, product description is correct (did what I promised). Used cables for fairly long runs (60ft) with Klipsch 5800-C II ceiling speakers (for home sound system) and couldn't tell any difference between 60ft and 3ft. The white jacket means that room inscriptions can be applied directly to the wire. Leg markers are great and save a lot of time when trimming. While ease of installation isn't necessarily a priority on individual projects (compared to sound quality and material durability), installation was very easy: the shroud slides on without snagging or tearing. The wire is very flexible and stays the way you want it rather than being springy.
