AudioQuest SureGrip 300 Multi-Spade Speaker Connectors (Tray of 40)

The AudioQuest SureGrip 300 Multi-Spade Plugs deliver a robust, high-fidelity connection between speaker cables and binding posts, engineered for demanding stereo and home-theatre systems. These spade plugs accept thick speaker cables up to 9 AWG, offering a low-resistance path and secure mechanical contact — ensuring reliable signal transfer even under heavy load or high power playback. Their build quality and precise termination method make them ideal for long-term installations or high-performance speaker systems.

High-Purity Beryllium-Copper Core for Efficient Signal Transfer

Each SureGrip 300 Multi-Spade Plug uses a beryllium-copper core known for excellent conductivity and mechanical strength. This metal choice reduces resistance and ensures the electrical connection remains stable over time. With such a conductive path, the audio signal retains its integrity — delivering tighter bass, clearer mids, and more accurate highs compared with standard connector metals.

Direct Gold or Silver Plating Without Nickel for Clean Signal Path

These spade plugs use direct plating of gold or silver directly onto the beryllium-copper core. By avoiding intermediate nickel or less-conductive layers, signal purity is preserved at the termination point. This plating approach minimizes contact resistance and helps prevent sonic coloration or distortion that can arise from inferior plating systems, leading to more transparent, neutral audio reproduction.

Key Features
  • Beryllium-Copper core for high conductivity and strength, enabling stable signal transfer
  • Direct gold or silver plating without nickel or inferior layers — maintains signal purity at the connection
  • Cold-weld termination system — solder-free, tight, low-resistance mechanical bond
  • Supports speaker cables up to 9 AWG — suitable for high-current, power-hungry speakers
  • Compatible with standard binding posts (1/4 inch to 5/16 inch) — broad amplifier and speaker compatibility
  • Ideal for bi-wiring, bi-amping, or multi-speaker installations — professional-grade connectivity
