Know before you buy
The Cold-Weld system creates a permanent, high-pressure connection between your cable and the connector without the need for solder. This prevents the signal degradation that can occur when heating metals during traditional soldering.
Purple Copper is a higher-purity metal that offers better conductivity and lower distortion than standard brass. By eliminating brass from the signal path, these connectors ensure a cleaner, more accurate audio signal.
These are multi-spade connectors designed to fit a wide range of standard speaker binding posts. The spade design provides a large surface area for a secure, low-resistance connection.
Yes, you will need basic hand tools to tighten the set screws for the Cold-Weld connection. The process is straightforward and designed to be completed easily by the end user.
The POM (polyoxymethylene) casing is used because it is non-conductive and durable. It protects the connection point while ensuring that the housing does not interfere with the electrical signal or cause unwanted capacitance.
