# Flex Audio 14/2 Speaker Cable - 2 Core - LSZH

The Flex Audio OFC Speaker Flex 14AWG 2 Core is a professional-grade LSZH speaker cable offering a heavier gauge conductor for installations where low resistance over longer cable runs is essential, including large home cinema rooms, open-plan living spaces, and multi-room audio systems.

Built with 99.9999% pure oxygen free copper, the 14AWG conductors deliver a conductor DC resistance of less than 9.2 Ω/km — significantly lower than 16AWG equivalents — making this cable the better choice wherever cable runs are extended or speaker loads are more demanding.

The LSZH (Low Smoke Zero Halogen) outer sheath meets IEC60332-1, IEC60754, and IEC61034 standards, making it a responsible and regulation-compliant choice for permanent installations in occupied buildings, schools, hotels, and commercial premises where fire safety matters.

-   **Heavier 14AWG Gauge:** Thicker conductors offer lower DC resistance than 16AWG cable, reducing signal loss over longer runs and delivering more power to the speaker with greater efficiency.
-   **Oxygen Free Copper:** 99.9999% pure OFC construction ensures maximum conductivity and long-term signal integrity for audiophile and professional installations alike.
-   **LSZH Sheath:** Low smoke, halogen-free outer sheath reduces toxic emissions in the event of fire, meeting IEC60332-1, IEC60754, and IEC61034 requirements.
-   **EN50575 CPR Rated:** Carries an Eca CPR classification as standard, with Cca, s1a, d1, a1 available for projects requiring a higher fire performance rating.
-   **2 Core Configuration:** Clean, straightforward two-core layout with Black and Red colour coding for fast, accurate polarity identification during installation.
-   **Wide Temperature Range:** Rated from -20°C to 80°C, suitable for installations in loft spaces, plant rooms, and other environments subject to temperature variation.
