Audio speaker cable SCP SP-1.5/2-LSZH-WT, copper conductors AWG16, low smoke halogen-free, white, 305 m

SCP SP-1.5/2-LSZH-WT is a 305 m speaker cable with two copper conductors sized 1.5 mm² (approx. AWG16) and a low-smoke, halogen-free white jacket. It is intended for fixed installations and audio distribution systems such as public-address, conference and background-music setups, providing consistent signal transmission between amplifiers and loudspeakers while meeting fire-safety standards for reduced smoke and halogen emissions.

Advantages

The cable combines oxygen-free copper conductors with a flexible stranded construction to maintain good conductivity and reliable audio performance. Its LSZH (low smoke zero halogen) outer jacket lowers toxic and corrosive gas output in case of fire, and the B2ca fire classification ensures compliance with stricter building regulations. Supplied on a 305 m reel in white, it is suitable for long runs and discreet installation in commercial or institutional environments.

Suitable for

• Fixed in-wall or in-ceiling speaker wiring in commercial buildings
• Public-address and evacuation systems
• Background music and paging systems in retail or hospitality
• Long runs between amplifiers and speaker arrays

When it may not be suitable

This cable is designed for fixed permanent installations and is not intended for frequent flexing or direct connection to portable loudspeakers where repeated movement occurs. It also may be unnecessary for small domestic projects where simpler, lower-specification speaker cable would suffice.

Key specifications

• Length: 305 m (reel)
• Conductor: oxygen-free copper, stranded
• Conductor size: 1.5 mm² (approx. AWG16), 2 conductors
• Construction class: standard flexible (class 5 strand)
• Jacket: low smoke zero halogen (LSZH), white
• Fire performance: B2ca-s1a,d1,a1 per EN 50575

How to use

Route the cable through walls, ceilings, or cable trays to connect amplifiers and speaker terminals. Strip the jacket and insulation carefully to expose the stranded copper conductors, then terminate with appropriate connectors or binding posts ensuring correct polarity. Secure the cable along its run to prevent strain on terminations and follow local building and fire-safety regulations when installing in public or escape-route areas.

What to consider before purchase

• Required run length and whether a 305 m reel matches project needs
• Compatibility with speaker and amplifier terminal types
• Installation environment and the need for LSZH and B2ca fire performance
• Whether a more flexible or portable-rated cable is needed for movable speakers

Usage recommendations

For best audio performance, keep cable runs as short as practical, maintain correct polarity between amplifier and speakers, and use secure, low-resistance terminations. When installing in occupied or escape-route spaces, choose LSZH, B2ca-rated cable like this model to minimise smoke and toxic gas risks.
