Machined of pure copper.
Then plated with copper.
Originally made for Audial amplifiers, these binding posts are now available as DIY or OEM parts.
They accept the usual 4 mm banana connectors (axially) and 6.3 mm (0.25″) spade lugs. And they fit 1-6 mm thick amplifier panels, requiring 10 mm (0.4″) holes. We ship 1 mm and 1.5 mm deep grommets and a washer for each binding post, so you can combine them to suit your needs the best.

Rationale
As opposed to conventional binding posts and connectors in general, usually made of copper alloys, mostly brass and sometimes bronze, which improve on copper mechanical properties, making the production more practical and less expensive, Audial binding posts are made of real, 99.98% pure copper.
It is important to understand: alloys, and electroplating by other materials, are used for practical reasons. Purely sonically, they are nothing but compromise.
Real copper connectors can be easily distinguished from ubiquitous brass products, and even from copper connectors plated by precious metals, for their natural and relaxed tone, and higher resolution.
We don’t regularly produce a long thread version of these binding posts anymore.
The long thread version, intended for use at up to 20 mm thick loudspeaker panels, is now available only on special request (please ask for a quote).
