14/4SPTC-DB-152M

14/4SPTC-DB-152M - 4x 2.5mm speaker cable, 14AWG, LLDPE, for direct burial, 152m reel, black

SCP 14/4SPTC-DB-152M is a four-conductor 14AWG speaker cable from the Pro Series, designed for direct burial and outdoor installations. The conductors are made of tinned oxygen-free copper (OFC) with a high number of strands (105 x 0.16mm, actual cross-section approx. 2.11mm²), ensuring efficient transmission of speaker signals in outdoor sound systems. The cable performs well in advanced garden and landscape speaker systems, in professional outdoor audio installations, and in home theater systems. It can be laid directly in the ground without a protective conduit. The gel filling protects the cable from moisture, while the UV-resistant LLDPE jacket provides high puncture resistance, flexibility in low temperatures, and rodent resistance. Four conductors in PVC insulation form two twisted pairs wrapped in PET tape: the first pair has black and red conductors, and the second green and white. This arrangement facilitates the identification of tracks and polarity when connecting speakers. The cable is supplied on a 152m wooden reel made from recyclable materials.
