Good quality speaker cable. Connectors are very well made and durable. Just the right length for bar and restaurant gigging. These cables should last a very long time as the materials are of a superior quality to cheaper types available elsewhere.
As a note, these are specifically suited to connecting a power amplifier or integrated power amp mixer to passive PA speakers as they are designed to carry high capacity electrical signals. If your system is comprised of an amplifier with passive speakers, use these and NOT standard XLR microphone cables (which are only really suitable for powered or "active" speakers) as you will damage the XLR mic cables or your amp.
