    Good cable. Little stiff but was easy to work with.

    High quality wire for high end sound systems at a very reasonable price. Delivery in a timely manner at a nominal fee. Overall outstanding value.

    Im sure different people have their preferences, but I always felt 12G was what I wanted, long term for my sitting room speakers. I chose Monoprice 250ft cos of the length (to reach the two back speakers). And I wasnt disappointed, thick but flexible and solid. Looks like the kind of wire that will last for ages, which is important for me because I plan to upgrade my speakers say in 2 years time, but Id rather not have to rewire when that time comes. Especially because I had to wire into ceilings and walls to keep the setup neat.

    Worked great in wiring my living room for my speakers and new receiver. Very pleased with product.

    At the time that I bought this 250 spool of 12AWG oxygen-free copper (not copper-clad aluminum) wire a year or 2 ago, it was the absolute best price I could find. As a matter of fact, I believe it was cheaper than other brands 14AWG OFC wire anywhere else. So the value is great. As for the wire gauge being true to size, I believe it is, or extremely close to it. Ive bought wire from multiple sellers/brands in the past, and a lot of times they advertise their wire one or two AWG sizes larger than it truely is. Due to that, I needed 14AWG wire but ordered 12AWG to make up for any upscaled false advertising. Regardless, this wire ended up being pretty true to size or very close to it. I used this to connect 4 big custom speaker enclosures that I hung in the upper corners of our 3-stall garage/shop. I still have some left that I occasionally use for automotive purposes, and I usually cut/pull the white loom/sheathing off first. However if you do remove that white sheathing, I dont recommend using it in a place that will either rub other objects that could wear through the insulation from vibration or movement, or melt through from heat. The wires have a thinner, cheaper insulation. I also dont really recommend using it in outdoor areas, and that includes on vehicles in engine bays or exteriors, because it wouldnt be as protective against the outside elements. The copper will likely oxidize much sooner in those applications. For indoor speaker wiring applications, its great.

    Installed for klipsch theater set up. Enough for 12 runs in a 20x12 room with 250ft

    For about $100 I pre-wired our new houses media room for 7-speaker audio with 12AWG wire. Cant beat that value!

Get the most out of your home audio system with high quality, oxygen-free, pure bare copper speaker wire from monoprice!

this speaker wire features two conductors made of high purity (greater than 99.95% pure), oxygen-free bare copper. Pure bare copper is a superior conductor to the copper clad aluminum (CCA) conductors used in most other inexpensive speaker wire. Cca is only about 68% as conductive as pure bare copper. This additional resistance is added to the impedance of your speakers and can negatively effect The sound.

for the wire to have no audible effect, The total wire resistance should be no more than 5% of the lowest impedance of your speakers. Even speakers rated for a nominal 8-ohms, may dip to as low as 4-ohms at some frequencies, which further reduces the total cable resistance allowed in the wire. Using pure bare copper speaker wire ensures that the total load put on the amplifier remains as close as possible to the impedance curve of your speakers.

for example, a 16AWG 2-conductor pure bare copper speaker wire has a total resistance of 0.803 ohms per 100 feet (both directions must be considered). by comparison, a 16AWG 2-conductor CCA speaker wire has a total resistance of 1.181 ohms per 100 feet. Assuming 4 ohms is the lowest impedance of your speakers, a speaker wire run can be no more 0.2-Ohms total. 20 feet of 16AWG pure bare copper would be 0.1606 ohms, well under the 0.2-Ohm limit. On the other hand, 20 feet of 16AWG CCA would be 0.2362 ohms, well over the 0.2-Ohm limit.

each conductor is jacketed with color-coded PVC for easy polarity identification. The entire cable assembly is jacketed in a white, CL2-rated PVC material. The CL2 rating indicates that the cable complies with fire safety and insurance requirements, making it safe for use inside the walls of residential class buildings.
