Its 4-conductor design streamlines bi-wiring and cable management, delivering superior conductivity and durability for high-end sound systems. ## Description From the manufacturer Monoprice 102820 100ft 14AWG CL2 Rated 2-Conductor Loud Speaker Cable (for in-Wall Installation) 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. Review: The Pro Choice for In-Wall Projects – Clean, Safe, and Reliable - If you are running speaker wire through walls, under floorboards, or into a ceiling for a home cinema, you shouldn't just use any old "zip cord." This Monoprice 100ft spool is specifically designed for permanent installations, and the 4-conductor setup is a total game-changer for cable management. ​The "4-Conductor" Advantage ​Most speaker wire is 2-conductor (Positive/Negative). This cable houses four separate 18AWG wires inside a single outer jacket. ​Tidier Runs: Instead of pulling two separate cables from your AV receiver to a pair of speakers, you pull one cable. You then split the white/green and red/black pairs at the destination. It makes the "fishing" process through walls twice as fast and half as messy. ​Bi-Wiring: If you have high-end speakers that support bi-wiring, this single cable handles both the high and low frequencies perfectly. ​Safety & Build: CL2 Rated Pure Copper ​The "CL2" rating is the most important part of the spec sheet. It means the outer jacket is fire-resistant and rated for in-wall use to meet building codes. ​OFC (Oxygen Free Copper): Unlike "CCA" (Copper Clad Aluminium) which is cheaper but brittle and has higher resistance, this is Pure Bare Copper. You get better conductivity and it won't oxidise or become brittle over time. ​18AWG Gauge: This is the "Goldilocks" thickness for most home setups. It’s thick enough to maintain signal integrity over the full 100ft (30m) run without losing volume or high-end detail, but thin enough to be flexible around corners. ​Installation Tips ​The outer white jacket is smooth, which helps it slide through conduit or holes in studs without snagging. ​Note: Because it’s a 4-conductor cable, it is slightly thicker and rounder than standard flat speaker wire. If you’re planning to run it under a thin carpet, it might leave a slight visible "bump"—but for walls and ceilings, it's perfect. ​Final Verdict ​Pros: CL2 Fire-rated (essential for insurance/safety); Pure Copper (not the cheap aluminium stuff); 4-in-1 design saves massive time on installs. ​Cons: Slightly stiffer than 2-conductor wire; might be too thick for very small "designer" cable trunking. ​For a 100ft spool of pure copper, the price is unbeatable. It’s professional-grade gear that ensures your home cinema sounds as good in 10 years as it does on day one. Review: Great quality speaker wire and well priced - Very good quality speaker wire and pretty easy to work with. I found these by Monoprice to be just the right thickness, any thicker and they might be a problem for tight areas, and the sound quality from them is worthy of a medium to high-end sound system. ## Features - 100 continuous feet of 14AWG 2-conductor speaker wire on a spool - Designed with CL2 rated outer jacket for safe usage within the walls - International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001WHQ9C8 | | Best Sellers Rank | 32,207 in Electronics & Photo ( See Top 100 in Electronics & Photo ) 272 in Speaker Cables | | Brand | Monoprice | | Cable Type | Composite | | Cable type | Composite | | Colour | White | | Compatible Devices | Speaker | | Compatible Phone Models | No Compatible Phone Models | | Compatible devices | Speaker | | Compatible phone models | No Compatible Phone Models | | Connector Gender | Male | | Connector Type | Bare Wire | | Connector type | Bare Wire | | Country Of Origin | Hong Kong | | Customer Package Type | Standard Packaging | | Customer Reviews | 4.7 out of 5 stars 1,728 Reviews | | Data Transfer Rate | 14 Gigabits Per Second | | Gauge | 16.0 | | Global Trade Identification Number | 00710348838820, 00844660028208 | | Included Components | 14AWG CL2 Rated 2-Conductor Speaker Wire | | Indoor Outdoor Usage | Indoor | | Item Length | 100 Feet | | Item Shape | Round | | Manufacturer | Monoprice | | Manufacturer Part Number | 102820 | | Maximum Voltage | 100 Volts | | Model Name | 102820 | | Model Number | 102820 | | Number of Items | 1 | | Number of Pins | 2 | | Other Special Features of the Product | In-Wall Installation | | Outer Material | Fire-resistant PVC or similar plastic | | Recommended Uses For Product | Speakers | | Specification Met | CL2 | | UPC | 710348838820 844660028208 | ## Product Details - **Brand:** Monoprice - **Cable type:** Composite - **Compatible devices:** Speaker - **Connector type:** Bare Wire - **Special feature:** In-Wall Installation ## Images ![Monoprice 102820 100 ft 14AWG CL2 Rated 2-Conductor Oxygen Free Pure Bare Copper Speaker Wire Cable, White - Image 1](https://m.media-amazon.com/images/I/51+HNdPeHQL.jpg) ![Monoprice 102820 100 ft 14AWG CL2 Rated 2-Conductor Oxygen Free Pure Bare Copper Speaker Wire Cable, White - Image 2](https://m.media-amazon.com/images/I/31i03v8HmiL.jpg) ![Monoprice 102820 100 ft 14AWG CL2 Rated 2-Conductor Oxygen Free Pure Bare Copper Speaker Wire Cable, White - Image 3](https://m.media-amazon.com/images/I/31ncrvLhAOL.jpg) ![Monoprice 102820 100 ft 14AWG CL2 Rated 2-Conductor Oxygen Free Pure Bare Copper Speaker Wire Cable, White - Image 4](https://m.media-amazon.com/images/I/31seUa0zDyL.jpg) ![Monoprice 102820 100 ft 14AWG CL2 Rated 2-Conductor Oxygen Free Pure Bare Copper Speaker Wire Cable, White - Image 5](https://m.media-amazon.com/images/I/31YPzb3ER0L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ The Pro Choice for In-Wall Projects – Clean, Safe, and Reliable *by S***R on 21 March 2026* If you are running speaker wire through walls, under floorboards, or into a ceiling for a home cinema, you shouldn't just use any old "zip cord."
