Red black speaker cable (standard type RVB) is a twin-core parallel unsheathed flexible cable with a simple core structure. It is mainly used to connect power amplifiers and loudspeakers for transmitting audio power signals.
Electrical Conductivity
Low resistance: Stranded pure copper design features low resistance, reducing power loss and signal attenuation. Thicker wire diameter results in lower resistance, making it suitable for longer-distance or high-power transmission.
Mechanical Properties
High flexibility: Stranded construction plus PVC material ensures excellent softness, easy bending and routing, and resistance to breakage.Flat shape: Parallel structure prevents tangling, facilitates organization and fixation, and occupies little space.
Application Characteristics
Polarity identification: Red and black color coding makes it extremely easy to distinguish positive and negative poles during installation, avoiding equipment damage from reversed connection.
Universality: With simple structure and low cost, it is the most common wire for low-to-mid-range audio systems such as household, automotive, and public address systems.
