Speaker cable HELUSOUND® 450 EXTREME FLEX PVC 2x1.5 mm² black, colored conductors 11017574

Professional speaker cable for demanding applications

The HELUSOUND 450 extreme FLEX cable is a flexible solution for professional audio installations, both in stage and event environments. It is perfect for organizing events, concerts or conferences. Its exceptional flexibility and resistance to external factors make it an ideal choice for temporary applications, including outdoor use.

This black cable with a cross-section of 2x1.5 mm² is designed for durability and reliability. The construction with multi-strand copper conductors, class 6, ensures excellent conductivity and resistance to repeated bending. PVC insulation guarantees safe use, and twisted strands with an optimal pitch minimize interference.

Construction and properties

The cable is characterized by high flexibility, which facilitates installation and laying even in difficult conditions. The minimum bending radius – 8x cable diameter for flexible operation and 5x diameter for fixed installation – allows adaptation to the specifics of the installation. The operating temperature range from -30°C to +70°C (flexible) and from -40°C to +70°C (stationary) ensures reliable operation in various environments.

• Conductors: Copper, unplated, multi-strand class 6 – provide good conductivity and flexibility.
• Insulation: PVC – guarantees safety and durability.
• Sheath: PVC in black color (RAL 9005) – resistant to mechanical damage and atmospheric factors.
• Conductor resistance: 13.3 Ohm/km for a cross-section of 1.5 mm² – minimizes signal loss.
• Flame retardancy: Compliant with IEC 60332-1-2 and PWIS: VW PV 3.10.7 – increases safety.

The HELUSOUND 450 extreme FLEX cable is a solid choice for installers and users who value quality and reliability in professional audio systems. It will work well in recording studios, cinemas, theaters, as well as during outdoor events.
