Speaker cable HELUSOUND® 450 EXTREME FLEX PVC 2x2.5 mm² black, colored conductors 11017575

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 audio cabling. Designed for stage, touring and conference systems, it provides a reliable connection and excellent sound quality.

Construction and properties

The cable is made of multi-strand copper conductors with increased flexibility (class 6), guaranteeing exceptional flexibility and ease of laying even in difficult conditions. The conductors are insulated with PVC and available in red and black colors, making it easy to identify polarity. Twisting the conductors with an optimal pitch minimizes interference and ensures a stable signal. The whole is surrounded by a durable black PVC jacket (RAL 9005), resistant to UV radiation, making it ideal for outdoor use.

Additionally, the cable meets the IEC 60332-1 standard for fire resistance (PWIS: VW PV 3.10.7), increasing safety. The conductor resistance is a maximum of 7.98 Ohm/km for a cross-section of 2.5 mm², which minimizes signal loss over longer cable lengths.

Applications and user parameters

The HELUSOUND® 450 EXTREME FLEX cable is perfect for:

• Stage and touring installations: thanks to its flexibility and durability, it is ideal for frequent winding and unwinding during concerts and musical events.
• Conference systems: provides high-quality sound transmission in conference rooms, recording studios, cinemas and theaters.
• Temporary (outdoor) installations: UV resistance allows for safe outdoor use for extended periods.
• Mobile audio systems: lightweight construction and ease of transport make it an excellent choice for people who frequently change location.

The minimum bending radius is 8 x cable diameter for flexible laying and 5 x diameter for fixed laying, making installation easier even in tight spaces. The cable retains its properties over a wide temperature range – from -30°C to +70°C (flexible) and from -40°C to +70°C (stationary). The operating voltage is 300V. The outer diameter of the cable is 7.5 mm and its weight is 0.101 kg/m.
