AudioQuest 507 Series Multi-Spade Speaker Connectors (Set of 4)

The AudioQuest 507 Series Banana Plugs deliver a high-end, reliable way to terminate speaker cables and connect to amplifiers or speakers. Engineered for heavy-duty and high-fidelity systems, they accommodate speaker wire up to 7 AWG and are crafted to preserve signal integrity from source to speaker. Their robust build, precise contact design, and premium materials make them a top-quality choice for serious stereo rigs or home theater systems.

One-Piece Purple Copper Construction for Pure Signal Transfer

Each 507 banana plug is machined from a single solid piece of high-purity Purple Copper. This one-piece construction avoids the performance compromises of less-expensive, multi-part or brass plugs, ensuring a strong, consistent electrical path with minimal distortion. By using a high-grade conductor metal, the plugs maintain accurate and clean signal flow for bandwidth, dynamics, and detail preservation.

Direct Hanging-Silver Plating for Low-Loss, High-Fidelity Contact

The contact surfaces of the 507 Series are coated using a hanging-silver plating process rather than standard drum-tumbler methods. This results in a thick, uniform silver layer directly bonded to the copper core — with no intervening inferior metals. The direct plating reduces contact resistance and avoids sonic degradation sometimes introduced by nickel or other intermediary layers, supporting clarity, resolution, and tonal neutrality in playback.

Key Features
  • One-piece high-purity Purple Copper body — strong, distortion-free conduction path 
  • Hanging-silver direct plating — low contact resistance, no intermediary metal layers to degrade signal 
  • Cold-weld clamping system — solder-free, secure, and low-resistance termination
  • Accepts speaker cables up to 7 AWG — supports high-current, high-power applications 
  • Compatible with standard banana jacks/binding posts — broad amplifier and speaker compatibility 
  • Pack size and configuration options — set of 4 (full-range) or bi-wire/bi-amp packs available
