Omnitronic 3030021L kaiutinkaapeli 2x2,5 mm², 50 m, musta

Omnitronic 3030021L speaker cable is a 50 m long, black two-conductor cable with 2 x 2.5 mm² conductor cross-section, designed to provide a reliable low-voltage connection between amplifiers and loudspeakers. The cable is intended for fixed or semi-permanent speaker installations in venues, rehearsal rooms, studios and home audio systems where longer cable runs and consistent signal transmission are required. Its flexible outer sheath and adequate conductor size support stable audio performance for a variety of speaker types.

Advantages

This speaker cable combines a generous conductor cross-section with flexibility, enabling lower resistance and improved power handling over extended lengths compared with thinner cables. The 50 m length allows long runs without the need for additional joins, reducing potential points of failure. The black outer sheath provides a neutral appearance suitable for professional installations and home setups, while the two-conductor design simplifies speaker polarity identification and connection.

How to use

Strip the outer sheath and the individual conductor insulation to the required length, taking care not to nick the conductors. Connect the two conductors to the corresponding positive and negative terminals on the amplifier and speaker, observing correct polarity to maintain phase consistency. For long runs, avoid tight bends and secure the cable at intervals to prevent strain. If the cable is installed in permanent or semi-permanent locations, ensure proper routing through cable management systems or conduits where required by local regulations.

Recommendations

For optimal audio performance use the full conductor cross-section without unnecessary splices; when joins are unavoidable, use soldered connections or approved speaker cable connectors and protect joints with heat-shrink tubing or approved junction boxes. Keep speaker cable runs away from mains power cables to minimize interference, and choose termination methods (banana plugs, spade lugs or direct screw terminals) compatible with the amplifier and speaker terminals.
