Description
Most generic connectors are made of hard, low-conductivity metals just to maintain their structural shape. The EGM Audio Reference Speaker Banana Plugs shatter this compromise by using Australia’s first laboratory-certified, 99% ultra-pure copper core. By pairing pure copper conductivity with an ultra-strong, high-tensile steel tension spring, these plugs slide effortlessly into your binding posts with absolute contact force. They remove the bottlenecks in your signal path to deliver an explosive, highly transparent audio performance with an unyielding mechanical grip.
Batch-Tested 99%+ Pure Copper Core
Maximum Conductivity
Crafted from high-purity copper rather than standard brass. This drastically reduces electrical resistance across the plug interface.
Independent Lab Verification
Randomly sampled plugs from every single manufacturing batch are sent to TAC Bullion (a local bullion dealer) for definitive metallurgical analysis.
QR-Code Transparency
Includes a scannable QR code on the packaging, allowing you to instantly view the independent chemical purity certificate for your exact batch of plugs online.
Specialized High-Tensile Steel Tension Spring
The Hybrid Solution
Because pure copper is naturally soft, traditional copper banana plugs lose their tight friction fit over time. EGM solves this by embedding a high-tensile steel outer spring over the copper pin.
Universal Fitting
The spring geometry provides consistent tension to adjust and lock perfectly inside almost any manufacturer’s 4mm speaker terminal or binding post.
Heavy-Duty Dual-Screw Termination
Dual 2mm Hex Grub Screws
Features two large, independent hex-head grub screws that squeeze the bare wire securely against the copper inner barrel. This eliminates the risk of loose connections or wires pulling free.
Thick Wire Clearance
Built with an extra-large interior termination capacity designed to accept heavy-gauge audiophile speaker cables up to 5mm in diameter (10 AWG).
Plating and Shell Variations
Gold Plating
Provides a classic, highly conductive, and corrosion-resistant surface finish.
Rhodium Plating
Offers extreme material hardness and total protection against atmospheric oxidation, mechanical scraping, and silver/gold tarnish.
Nude or Shielded Configurations
Available completely bare (“nude”) or housed in non-conducting, red and black anodised aluminium sleeves to completely prevent accidental short-circuits if the plugs touch each other behind your amplifier.
Pack Size
Shipped in a premium retail 8-pack box (comprising 4 matching pairs) to fully terminate a standard stereo pair of speaker cables.
