These aeco ABI-0611S speaker terminals offer excellent design quality. They use low-mass contacts made of high-purity tellurium copper with silver 120µ plating, ensuring both excellent conductivity and resistance to oxidation. The body of the terminal blocks is meticulously machined from a single piece of polyoxymethylene (POM) using CNC (numerical control). An internal cable is simply fitted using a screw system. These terminal blocks also accept bare wires (Ø4mm max), banana plugs and forks (Ø6/8mm).
