Use AudioQuest SureGrip 100 Multi-Spades to create a secure, high-performance connection between your speaker cable and loudspeakers. AudioQuest uses High-Purity Purple Copper base metal, which is stronger, more conductive, and sounds better than the typical phosphor-bronze used in most connectors. Direct-Gold/Silver Plating looks great while avoiding sonically degrading intermediary layers of lesser-quality metal. The included mini-wrench creates a simple, secure cold-weld connection without requiring sound-damaging solder. Bare speaker wire is messy and unreliable. Compatible with universal speaker binding posts and cables up to 9AWG, AudioQuest SureGrip 100s create a clean, finished look while ensuring excellent sonic performance.
