Reverb speaker cables are a pair of two transparent wires used to make connections across speakers, audio amplifiers, and other audio components in offices, residential complexes, shopping malls, and stadiums.
Both wires of the speaker cable are electrically identical, but for easier identification, one of the wires is marked with a strip of Pressfit’s bright orange tracer along the entire length of the cable. This way, it becomes easy to remember and connect the correct cores as per the polarity at both ends of the cable.
Pressfit’s Reverb Speaker Cables are manufactured using bright annealed bare copper (BC) conductors for a clear, distortion-free voice with low dB loss. The electrical signals sent over these wires get converted into mechanical movements, causing the cones of speakers and subwoofers to vibrate with the appropriate rhythm, volume, and frequency.
Like all cables, Pressfit’s Reverb speaker cable has three main characteristics: capacitance, inductance and resistance. Due to the nature of its application , resistance becomes the most important. Most speaker systems have an impedance between about 3-4 Ω and about 15 Ω. Most speaker systems today have an impedance between 4 Ω and 8 Ω.
As the resistance in the cable increases, it will gradually affect system performance and audiophiles are usually concerned about the change in the speaker’s sound quality. Typically, the effects of the speaker cable are felt when the resistance of the cable approaches about 5% of the speaker impedance.
The resistance of the speaker cable can be altered by three main elements:
The resistance of the speaker cable is proportional to its length. So, it is a best practice to keep the length as short as possible.
The cross-sectional area or gauge (AWG) of the speaker cable has a major impact. The smaller the cross-section, the higher the resistance. It is therefore wiser to always choose a cable with a larger area.
Copper is usually the standard choice of conductive material. It has very good conductivity, can be bent easily and the cost is quite acceptable. Oxygen-free copper theoretically offers better conductivity, but does not improve perceptible audio quality and is significantly expensive.
