- Speakon® Lockable Loudspeaker Connector / Chassis Connectors
- Extremely reliable and robust. 2,4 and 8 pole versions with `Quick Lock` system. The chassis types are fast and easy to wire with flat quick-connect terminations (e.g. Faston®). Excellent price / performance ratio. Speakon connectors are airtight for audio applications (leakage 30 cm3/s at 10 kPa differential pressure) unless otherwise stated.
