Use these spade connectors to terminate your speaker wire for optimal signal transfer, easier connection and disconnection and a great finished look. These compression type connectors will fit wire from 10 gauge to 16 gauge and can be installed in minutes with no tools needed. All you need to do is screw them on to the exposed wire. The Acoustic Research Performance Series includes many of AR's patented technical innovations for significant performance improvements over lesser brands. Some of them include: 24k gold contacts to maximize signal transfer and resist corrosion; Precision machined for a perfect tight fit; and a heavy duty design that allows these connectors to be connected and disconnected over and over again.
