Does Teufel Audio offer its own speaker cables?
Teufel Audio offers a large selection of cables in the accessories section. You can find our speaker cables here.
What is the difference between speaker cables and other cables?
Speaker cables have been specially developed due to their specific requirements for conductivity, signal quality, construction, and connection technology to ensure optimal audio transmission. These characteristics clearly distinguish them from other connection cables designed for different purposes and signal types.
Purpose and Signal Type
Speaker cables are specifically designed to transmit audio signals with minimal signal loss and the highest possible sound quality. Other cables such as RCA, HDMI, USB, or optical cables transmit data or low-level signals. This requires a special design and choice of materials.
Construction and Material
Speaker cables consist of two insulated conductors made of copper or tinned copper. The polarity is marked accordingly on the cables:
They usually have a larger cross-section to minimize electrical resistance. A low resistance is important so that the audio signal reaches the speaker without losses and thus ensures clear and powerful playback. Other connection cables, such as network cables, are often thinner because they transmit digital signals that are less susceptible to resistance losses.
Speaker cables do not have special shielding because they carry a strong signal that is less prone to interference. The insulation of the cables is also specially adapted to the requirements in the audio sector to minimize interference and maintain signal quality. Other cable types may use different materials or insulation better suited for their respective applications. For example, signal cables (e.g., RCA) are shielded to avoid interference with weak signals.
Conductor Cross-Section
Speaker cables have larger cross-sections (typically 1.5–4 mm²) to minimize losses at higher currents. Other connection cables often use thinner conductors because they only transmit small currents or digital data.
Impedance and Electrical Properties
Speaker cables must offer low resistance so that the amplifier can work efficiently. More on this here. Digital or analog signal cables often have defined impedances (e.g., 75 Ω for coax), which are crucial for signal quality.
Connectors
Speaker cables are often connected bare or with banana plugs. More information can be found here: Connecting Speaker Cables. Other cables have standardized connectors such as HDMI, USB, jack, RCA, DisplayPort, etc.
What influence does the speaker cable have on sound quality?
A speaker cable influences the sound – but only within physical limits. Pay attention to the recommended cross-section, length, material, and contact quality (how the cables are connected).
What impedance is recommended for speaker cables?
We recommend a maximum cable impedance of 0.4 ohms. Resistance would be a more appropriate term here, as measured impedance always depends on the frequency applied. However, for the cable, the frequency is not the relevant factor, but the length of the cable. The longer the cable, the higher the cable's resistance.
With 2.5 mm², you have a resistance under 0.4 ohms up to a length of 15 meters. Beyond this length, higher resistance occurs. However, if you choose a larger cable cross-section (e.g., 4 mm²) from this length of 15 meters onwards, you keep the resistance below 0.4 ohms.
Which speaker cable should I choose?
The speaker cables from Teufel are available in different thicknesses.
Length of the run / required cable length:
The longer the cable, the more important the cross-section: For short runs (up to 5 m), 1.5–2.5 mm² is almost always sufficient. For longer runs (10 m+), 2.5 to 4 mm² is advisable.
Reason: The longer the cable, the greater the cable's resistance. This means that with longer cable runs, power losses can occur and the maximum volume literally falls short.
Connection options on the speaker:
Of course, the cable should also fit into the connections of the satellites or speakers. Up to which cable cross-section the satellites are designed for is explicitly stated on the product pages.

How do I connect speaker cables?

Can I cut the speaker cable myself?
It is best to use side cutters to cut the cable. If you don't have any at hand, a utility knife or scissors will do in a pinch. Make sure not to damage the strands and to cut the cables cleanly.
Note: Cut or shortened cables are excluded from the contractual right of return.
If one of your speaker cables is too short, we have tips and tricks for extending speaker cables for you.
