12 AWG CL3 OFC Outdoor Speaker Wire, GearIT Pro Series 12 Gauge (100 Feet / 30.48 Meters / Black) Oxygen Free Copper UL CL3 Rated for Outdoor Direct Burial and In-Wall Installation Speaker Cable

Very good and nice quality

I was impressed with this cable it been waterproof and the length was very accurate I will be buying 2 more of these speaker wire functionality good quality No photos added at this time

As other reviews have stated this is a 2 pair wire, fully encased in a shielding (not just a regular slip on). By being completely encased they prevent moisture from become trapped and degrading the inside wires and also make this much more durable for underground burial. Definitely a well made product. The only thing they can improve is to add a single strand of wire to the center of it to make peeling the jacket a little easier. Either way, well worth spending a little extra time to get this to work. Works especially well with cable glands. The 12 gauge is about 10mm or 3/8 inch thick and the wire seemed very soft and easy to work with. Copper quality seems very good as well. Sound quality at 50 feet with this wire is the same as wiring the speakers directly to my amp.

I bought this wire because it has the most copper strands of any I could find. For sound quality that is perhaps the most important factor. The wire did not disappoint.

Used for garden speakers and subwoofer. Surprised by the quality, the copper is as thick as described.
