[For Audio Equipment] Recommended Speaker Cables! A Complete Guide to Choosing the Right Cable and the Sound Quality
Speaker cables are often overlooked in audio systems, but they play a very important role in delivering the amplified signal to the speakers, their final destination, without any degradation in quality.
It is no exaggeration to say that the true capabilities of your system will be brought out depending on the cable you choose.
In this article, we'll thoroughly explain everything from the basics of choosing speaker cables to recommended models by price range and the sound quality trends of each cable. Find the one that will dramatically change your listening experience.

Four important points for choosing speaker cables
Here are four basic points you should check first when choosing a speaker cable.
Conductor (core) material and purity
The conductor material is the most important factor that determines sound quality.
| material | Features | Sound quality trends | Recommended users |
|
OFC (oxygen-free copper) |
High-purity copper that does not contain impurities (oxygen). |
High resolution, clear and natural sound |
Well-balanced and excellent value for money. The foundation of audio. |
|
PC-Triple C/6N, 7N copper |
Even more highly purified copper wire. |
Well-balanced, relatively inexpensive and high performance |
High resolution, wide sound field, and more natural and detailed sound. |
|
Silver (or silver-plated copper) |
It has lower electrical resistance than copper. |
A sound with a sense of speed and a smooth high range | The high frequencies are extended, there is a sense of speed, and the sound is clear and brilliant. |
Cable thickness (cross-sectional area/AWG)
The thickness of the cable is related to "conductor resistance." The thicker the cable, the lower the resistance, and the more efficiently the amplifier's power is transmitted to the speaker.
Guidelines for appropriate cable thickness (low impedance systems)
For low-impedance speakers, such as 8 Ω or 4 Ω, typically used in home audio systems, it is important to choose a cable thickness that ensures that the cable's resistance is not too high compared to the speaker's impedance .
Cable resistance is inversely proportional to its thickness and proportional to its length. Lower impedances (e.g., 4 ohms) require thicker cables, as the effect of cable resistance on losses becomes more significant.

|
8 ohms |
Less than 3m |
1.25mm ² or more |
16 AWG or larger |
|
8 ohms |
Approximately 3m to 10m |
2.0mm ² or more |
14 AWG or larger |
|
4 ohms |
Less than 3m |
2.0mm ² or more |
14 AWG or larger |
| 4 ohms | Approximately 3m to 10m | 3.5mm ² or more | 12 AWG or larger |
* The smaller the AWG (American Wire Gauge) number, the thicker the cable.
Key Takeaways
-
Low impedance (e.g. 4 ohms) : The lower the impedance, the more current will flow, so a thicker cable is recommended to prevent power loss due to resistance.
-
Long-distance wiring : The longer the cable, the greater the resistance, so a good guideline is to choose a thicker cable and ensure that the cable resistance is within 10% of the speaker impedance.
-
High-output systems : When using a high-power amplifier, thicker cables are also advantageous in terms of allowable current (however, the above guidelines are usually sufficient for home use).
Typical home theater and audio systems use 1.25mm ² (16AWG) to 2.0mm ² (14 AWG) cables are often used.
Cable Construction and Shielding
-
Twisting method (structure): Single wire, multi-core twisted, Litz wire, etc.
-
Litz wire: A structure in which thin wires are insulated and twisted together. It is said to be effective in suppressing the skin effect (the phenomenon in which high-frequency signals flow along the surface of the conductor) and preventing attenuation of high frequencies.
-
-
Shielding: Speaker cables are not easily affected by noise, but if you are running them alongside power lines or other signal lines, it is safer to choose a model with strong shielding (external coating).
Terminal type (terminal processing)
How you handle the ends of your cables (the parts that connect to the speakers and amplifier) also affects sound quality and convenience.
-
Banana plugs: Simply insert them into the terminals of your speaker or amplifier to connect, making them easy to replace or remove.
-
Y-lug (spade plug): Can be firmly fixed with screws and increases the contact area. It is often considered to be advantageous in terms of sound quality.
-
Direct cable: A method of connecting by exposing the core wire without attaching a terminal. This is simple, but there is a risk that the cable is prone to oxidation and the connection may become unstable.
The tendency of "differences in sound quality" depending on the speaker cable
Some people say that cables don't change the sound, but speaker cables in particular are directly related to impedance matching between the amplifier and speaker, so it's said that the change is easy to feel.
Low-frequency resolution and driving power
If the cable is thin or has high conductor resistance, the bass power will be lost and the sound will tend to become muddy.
-
High-quality cable: Low resistance transmits the amplifier's power without loss, tightening the low range and improving the sense of speed and volume .
High-frequency extension and information content
If the conductor quality or twisting structure is poor, high-frequency signals will be attenuated or drowned in noise.
-
High-quality cable: The high frequencies extend clearly , and delicate information such as the reverberation of cymbals and the airiness of the sound are reproduced vividly.
Sound field width and positioning
If the cable has good transmission characteristics, the phase information recorded on the sound source will be accurately preserved.
-
High-quality cable: The position (localization) of instruments and vocals becomes clearer, and the sound field (stage expansion) feels more three-dimensional .
