Access™ Series 12AWG CL2 Rated 2-Conductor Speaker Wire, 500ft

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.

Pure Quality Comes At A Cost!

Pros: Realistically for the price. Everything.

Cons: For the quality expected, absolutely none.

I was doing a minor upgrade to my master bedroom's surround sound system with the installation of Kef T-305 7.2 speaker system. Was matching these with my Yamaha RX-A3030 AV. The Access Series 12AWG CL2 Rated 2-Conductor Speaker Wire, 500ft, was a small challenge fishing wire thru the walls, but the reward was well worth the effort. Where as I am unable to compare the before, I can truly say that my end setup is one of pure beauty to our ears. 12 awg wire was a slight overkill with 32ft runs, I would do a million times over, knowing my installation results, and with future proof. I've gotten my bang for a few extra bucks.

Pros: Great quality wire, solid, no imperfections
Jacket on the inner wires is tough (see con below)

Cons: Tough insulation on the wires makes stripping more time consuming than with some, but not overly difficult.

Pros: Easy to Pull
Lengths are clearly marked
Great quality overall

Cons: none

I have used this wire in multiple installations now and have not regretted it once. The most recent I was going back behind an installer and correcting his mistakes. I replaced some cheap undersized cable with this wire and the sound system went from dull and lifeless to vibrant and clear. The people could not believe the difference simply by using a quality cable that is the correct size. This was before any adjusting was done to anything other part of the system. I will continue to use this for all of my install needs.

Pros: CL2 Certified
Easy to pull through walls
Great price

Cons: None

Just what I expect when I order from Monoprice. Great price, fast shipping speed and high quality cable. Building an addition with a Home Theater gets expensive so it is nice to be able to rely on Monoprice to provide quality products while saving some $$.

Pros: Great cable. Great price. On par with cables three to four times as expensive.

Cons: None. It's 12AWG's supposed to be thicker than 14AWG and up. Duh.

Overall a great buy. The audio propagation quality of this cable is every bit as good as cables tripling and quadrupling in price. I measured the same and sometimes higher power values at the exact same distances as some other "audiophile quality" name brand cables I had left over from a previous project. No measurable difference in noise on the cable either. I will continue to buy only this cable for all of my customers from here on out.
