Best Speaker Wire

Article Contents

Speaker wire, whether rated for use in-walls, outdoor, or indoor-only, all has the same purpose: carrying audio signals from an amplifier, receiver, or radio to one or more loudspeakers. In theory, any wire designed for carrying electricity will work. The reality is that speaker wire is designed for audio, and is constructed differently. The outer jacket of speaker wire is marked for polarity to help ensure you connect speakers in phase (a pair of out of phase speakers will sound thin due to bass frequencies being canceled out). Speaker wire also uses purer, higher-grade copper which is more consistent in its electrical properties. Some companies make fanciful claims about this and that technology, but in general, thicker is better in terms of wire gauge and insulation thickness.

Our reviews cover three types of speaker wire. Indoor speaker wire is for general use in the home, and includes wire that some could consider audiophile. In-wall speaker wire is rated for safe routing inside of walls and has a level of fire resistance. Outdoor speaker wire is suitable for direct burial and is also designed to resist damage from heat, cold, moisture, and UV. There is nothing stopping you from using outdoor wire indoors or vice versa, but it just makes sense to use the right tool for the job at hand.

Best Indoor Speaker Wire:

Speaker wire is important for an obvious reason: it carries the electrical signal to your speakers from your amplifier or receiver. An electrician will tell you that any insulated wire can deliver current. But cable thickness, insulation, length, and other factors can affect how much of the pure audio signal gets to your speakers.

When it comes to speaker wire, the general rule of thumb is "thicker is better," especially in systems with long wire runs, or with speakers that demand lots of power. Higher gauge wire with more individual strands can handle more current and has less signal loss. Higher grade insulation, often called the jacket, can help prevent external electromagnetic fields from introducing noise or distortion to the audio. That being said, lower gauge wire (16 ga) can work fine in many consumer audio systems, and is easier to install and hide. And, for those audiophiles using very low power tube amplifiers combined with super efficient speakers, thinner cables mean less electrical resistance. But that is a special case, and the subject for a future best list.

We've judged our picks for best indoor speaker wire (cable) based on gauge, price, and quality of materials used.

          Best In Wall Speaker Wire:

          Our in-wall speaker wire reviews encompass similar criteria to those of our assessment of indoor speaker wire, with a critical difference: any wire used in a wall simply has to be CL2, CL3, or CM rated for fire resistance. The best wire will also have aspects such as flexibility and slipperiness that make it easier to route around insulation, anchors, and other structures in a wall. But beyond that, the best in-wall speaker wire will be audibly superior to standard wire, and feature a higher-grade of copper, and other features that maximize the delivery of audio from your amplifier or A/V receiver. Our selections of in-wall speaker wire are based on conductor quality and gauge, certifications for fire resistance, and price.

                Best Outdoor Speaker Wire:

                If you want to have music outside, you'll need to have some speakers outside. Wireless is an option, of course, but you'll have many more choices if you use wired speakers.

                Many indoor/outdoor systems have long wire runs that are 50 feet or longer. The speaker wire will likely be exposed to moisture, large differences in temperature from summer to winter, UV radiation, and perhaps even vermin. With that said, thick, low-loss conductors and, tough UV-resistant coverings are a must. A CL-3 rating is a good starting point. And the reality is that outdoor listening is not the same as listening to a half-speed mastered LP in your living room. Thus, our best outdoor speaker wire selections are based on wire gauge (thickness), jacket toughness, and price.
