Chassis Connectors

  

The Speakon panel mount connectors are the standard chassis connectors for loudspeaker / amplifier interconnections. They feature a unique metal locking system, making contact only once fully locked. The Speakon receptacles are robust, versatile and easy to terminate with either flat tab (Faston®) or screw terminals, pcb mount or soldering. They are available in 2, 4 and 8 pole configuration utilizing D size or G size panel cutout. The chassis connectors are airtight for audio applications (leakage 30 cm3/s at 10 kPa differential pressure) unless otherwise stated.

Termination
No suffix = solder termination or 3/16" flat tabs
