Access™ Series 16AWG CL2 Rated 4-Conductor Speaker Wire, 250ft

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 four 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.

Great wire for in-wall, on wall and outside!

Pros: Thin, two sets of wire inside white sleeve.

Cons: None

I used this to install in-wall speakers, a pair of surround speakers on wall, as well as inside a plastic conduit for outdoor install of Monoprice's outstanding rock speakers. Easy to work with and a quality product.

Pros: Great product for a great price

Cons: Spool is crap

Spool fell apart when I first started unwinding the wire making installing the wire just that much more difficult

This is great in wall speaker cable. It has a very thick pliable jacket. The strand count is high. The only thing I would like is 500ft spools. Or boxes.

I like the wire but hate the spool

Pros: Good price on quality wire. The jacket is a bit stiff but it works in your favor on some wire runs.

Cons: The spool is a cardboard tube with plastic ends and the last 3 out of 4 times I received this product one end of the spool is broken off.

This makes for a huge mess when pulling the wire as it will fall off the spool and be a big twisted mess. I have had to make end caps and pvc tube to hold together the broken spool. This product needs a hard plastic spool or a different design to prevent this from happening. I have been choosing other wire because of this problem. If you have the time to repair or rewind on a better spool then this is a great buy.
