PD Connex RX14 Speaker Cable – 100V Installation Cable for Professional Audio
The PD Connex RX14 is a 100V speaker cable designed for fixed audio installations in private and commercial settings. With a 2.5 mm² cross-section and 100 m length, it delivers reliable signal transmission for distributed speaker systems.
100 m length provides ample reach for multi-room or large-area audio installations
2.5 mm² cross-section ensures low resistance and consistent power delivery to speakers
CCA (copper-clad aluminium) conductor offers a cost-effective balance of conductivity and weight
Black outer jacket blends discreetly into installation environments
What sets the RX14 apart
The RX14 is built specifically for 100V line systems, the standard for distributed audio in commercial and institutional installations. Its CCA conductor keeps the cable lightweight and manageable while maintaining adequate conductivity for fixed speaker runs. The 100 m reel format is purpose-built for installation workflows, reducing the need for intermediate splicing.
Ideal for
Professional AV installers and system integrators working on commercial or private 100V speaker networks. Suitable for retail environments, offices, hospitality venues, and multi-zone audio setups where a single amplifier drives multiple speakers across long cable runs.
Application of PD Connex RX14
Run the cable from the amplifier output to each speaker location, keeping total impedance within the amplifier's rated range
Use appropriate 100V line transformers at each speaker to match impedance
Secure cable runs along cable trays, conduits, or wall channels per local installation standards
Connect speakers in parallel across the 100V line, ensuring the combined impedance stays within the amplifier's minimum load specification
PD Connex is a brand specialising in professional audio cabling and connectivity solutions for 100V installation systems. The RX14 speaker cable reflects the brand's focus on reliable, specification-driven cable products for fixed audio deployments.
It is a 100V speaker cable for fixed audio installations, connecting amplifiers to speakers in distributed speaker systems across commercial and private buildings.
The RX14 has a 2.5 mm² cross-section and comes on a 100 m reel, providing sufficient conductor area for typical 100V line runs.
The conductor is CCA (copper-clad aluminium), which combines aluminium core with a copper cladding for good conductivity at a lower weight and cost than solid copper.
The outer jacket is black, designed to blend discreetly into installation environments such as cable trays, conduits, and wall channels.
PD Connex provides a 24-month manufacturer warranty on the RX14 speaker cable, covering manufacturing defects under normal installation conditions.
