If you've ever stared at the back of a PA speaker or power amplifier wondering which cable goes where, you're not alone. XLR and Speakon are two of the most common connector types in live audio — but they serve very different purposes. This guide explains what each one does, when to use them, and how to avoid the most common mistakes.
XLR cables are the standard for carrying balanced audio signals between devices. You'll find XLR connectors on microphones, mixers, audio interfaces, and powered (active) speakers. The three-pin design carries a positive signal, a negative signal, and a ground, which allows the cable to reject electromagnetic interference — making XLR ideal for longer cable runs without noise or signal degradation.
XLR cables carry line-level or mic-level audio signals only — they are not designed to carry speaker-level power.
Speakon connectors were developed specifically for speaker-level connections — that is, the high-current signal travelling from a power amplifier to a passive speaker cabinet. Unlike XLR, Speakon connectors are designed to handle the much higher voltages and currents involved in driving speakers.
Speakon connectors lock into place with a twist, preventing accidental disconnection during a performance — a critical safety feature when dealing with high-power speaker systems.
| Feature | XLR | Speakon |
|---|---|---|
| Signal type | Balanced audio (mic/line level) | Speaker level (high current) |
| Typical use | Mic, mixer, active speaker input | Amp to passive speaker |
| Pin count | 3 pins (standard) | 2, 4, or 8 pole |
| Locking mechanism | Latch clip | Twist-lock |
| Max power handling | Low (signal only) | High (up to 40A per contact) |
No — and you shouldn't try. XLR cables are not rated for speaker-level current. Using an XLR cable to connect a power amplifier to a passive speaker can damage the cable, the amplifier output stage, or both. Always use a proper speaker cable with Speakon or 6.35mm (1/4") connectors for passive speaker connections.
If you're using powered speakers — which have a built-in amplifier — you only need XLR cables. The signal path goes from your mixer via XLR to the speaker's input, and the internal amplifier drives the speaker driver directly. No Speakon cables are needed.
For XLR signal cables, longer runs are generally fine thanks to the balanced design — runs of 30m or more are common in professional setups. For Speakon speaker cables, keep runs as short as practical to minimise power loss, and always use an appropriate cable gauge for the power levels involved.
