Speakon to Speakon Cable: What to Specify for PA and Installation Crews
The Speakon Cable Is the Most Handled Cable in the Rig
Speakon-to-speakon cables connect amplifiers to passive loudspeakers in PA systems, installed sound and touring rigs. They are plugged and unplugged on every show, coiled into cases and run across stages — so both ends of the cable matter: the connector has to lock reliably and take repeated abuse, and the cable inside has to survive the same treatment. This guide covers what to specify when you buy or build Speakon cable assemblies for PA and installation work.
The Connector: What Makes a Pro Speakon Different
The LBS LBSSPK Professional Speaker Twist Lock Connector is built for the duty cycle of professional audio:
- Heavy-duty glass-fibre reinforced, shatterproof shell with an impact-resistant insert — the connector survives being stepped on, dropped and packed.
- Fast, tool-free field assembly — technicians can terminate a cable on site without special tooling, which matters for rental repairs between shows.
- Integrated chuck-type strain-relief clamp — superior cable retention and pull-out resistance, so the termination does not fail when the cable is yanked.
- Smooth quick-release locking latch — solid, vibration-proof electrical contact that unlocks cleanly instead of jamming.
These features are exactly what to look for in a Speakon that will be used daily. For a full overview of the connector family, see the Speakon connector product page.
Pairing the Connector with the Right Cable
A Speakon assembly is only as good as the cable inside it. For PA work, the cable should be matched to the amplifier power and run length. For main feeds and subwoofers, a reinforced construction such as the tour-grade speaker cable guide recommends 2×4.0 mm² and 2×6.0 mm² sizes; for shorter monitor or satellite runs, smaller sizes work. The strain-relief clamp on the LBSSPK grips the cable jacket, so the jacket diameter should match the connector’s clamping range — a point to confirm with your cable supplier when ordering pre-made assemblies. The full range these connectors are specified with is in the professional speaker cable category.

Buying Speakon Cables: Pre-Made or Field-Terminated?
There are two practical routes:
- Pre-made assemblies — consistent quality, consistent length and factory-terminated strain relief; ideal for rental stock where every cable must behave identically.
- Field-terminated with LBSSPK connectors — useful for repairs and custom lengths on site, because the connector is designed for fast, tool-free assembly.
Many rental and installation companies use both: a standard set of pre-made lengths for the daily rig, plus spare connectors and cable for site repairs.
Speakon to Speakon Cable FAQ
Q: Can any speaker cable be used with Speakon connectors?
A: Speakon connectors are designed for two-core speaker cable. The key checks are conductor size matching the current and the jacket diameter fitting the strain-relief clamp. Reinforced speaker cable such as the LBSRVH series is a good match for touring and PA use.
Q: Why does the LBSSPK have a tool-free assembly design?
A: So technicians can terminate or repair cables on site without special tooling. The chuck-type strain-relief clamp gives strong cable retention while keeping field assembly fast — both matter for rental operations.
Q: Is the locking latch important for installed sound?
A: Yes. Vibration from loudspeaker cabinets can loosen ordinary connectors over time. The quick-release locking latch on the LBSSPK is designed to keep vibration-proof contact in both touring and fixed installations.
