Professional speaker cable for demanding applications

This flexible HELUSOUND® 450 EXTREME FLEX speaker cable is the ideal solution for both professional installers and those looking for high-quality cables for audio systems. Designed for stage, touring and temporary installations, it provides a reliable connection and excellent sound quality.

Construction and properties

The cable is characterized by exceptional flexibility, making it easy to install and lay even in difficult conditions. Made of multi-strand copper conductors with increased flexibility (class 6), covered with PVC insulation, it guarantees durability and resistance to mechanical damage. Colored conductors – red, black, blue, white, green, yellow, gray and purple – facilitate identification and correct connection. The outer PVC jacket in black (RAL 9005) protects the cable from external factors.

Additionally, the cable is UV resistant, making it particularly recommended for outdoor use. It can be operated in a wide temperature range – from -40°C to +70°C (stationary) and from -30°C to +70°C (flexible). The resistance of the conductors is a maximum of 7.98 Ohm/km for a cross-section of 2.5 mm². The cable meets the IEC 60332-1 standard regarding flame retardancy of a single cable (PWIS: VW PV 3.10.7). The minimum bending radius is 8x the cable diameter for flexible operation and 5x the diameter for fixed installation.
