Speaker cable PSSO 4 x 2.5 mm², 10 m, black

PSSO speaker cable with four conductors of 2.5 mm² cross-section and a 10 m black jacket is engineered for multi-channel and bi-wiring audio installations. The cable delivers reliable signal transmission between amplifiers and loudspeakers in home, studio or commercial environments. Flexible outer sheath and standard conductor dimensions simplify routing, bending and termination for both professional installers and DIY enthusiasts.

Advantages

The four-conductor design allows separate positive and negative runs for two speaker channels or bi-wiring a single loudspeaker, reducing interference and improving cable management. Conductors with 2.5 mm² cross-section balance current capacity and flexibility for typical speaker loads. The black jacket offers a neutral appearance for visible runs and provides mechanical protection against abrasion and handling during installation.

Suitable for

• Home stereo systems requiring two-channel or bi-wiring connections
• Multi-room and distributed audio installations
• Small commercial sound setups and meeting rooms
• Custom speaker runs where flexibility and neat routing are needed

Key specifications

• Conductor count: 4 cores
• Conductor cross-section: 2.5 mm² per core
• Length: 10 m
• Jacket color: black
• Outer sheath: flexible PVC (protective and insulating)

How to use

Measure and cut the required length of cable, taking into account routing paths and strain relief. Strip the outer jacket and insulate conductors only to the length required for termination. Connect corresponding positive and negative conductors to the amplifier and speaker terminals, observing polarity to maintain correct phase. For bi-wiring, use two conductors for the low-frequency terminal and two for the high-frequency terminal on compatible loudspeakers. Secure cable runs with appropriate clips or conduit to prevent mechanical stress.

Usage recommendations

For best performance, keep cable runs as short and direct as practical, avoid tight bends below the cable's minimum bend radius, and maintain correct polarity at both ends. In installations with long runs or high-power amplifiers, verify that the 2.5 mm² conductor size meets impedance and power-handling requirements for your speakers. Use proper termination types (banana plugs, spades or bare wire) matched to your equipment for reliable connections.
