The SA16SB20 speaker cable connects amplifiers with banana plug outputs to speakers with Speakon inputs, bridging different connector standards in professional audio setups. This 20-foot cable handles the transition between older amplifier designs and modern PA speakers that use the industry-standard Speakon connection.

Built with 16-gauge, 100% oxygen-free copper conductors, this cable delivers clean signal transfer with minimal resistance loss over the 20-foot run. The copper construction eliminates hum, buzz, and signal degradation that can occur with inferior conductors, ensuring your amplifier's power reaches your speakers efficiently.

The cable features professional-grade banana plug connectors on one end and a locking Speakon connector on the other, both built to withstand repeated connections in live sound environments. The durable PVC jacket provides protection against wear while remaining flexible enough for stage setup and breakdown. At 16 gauge, this cable handles moderate power levels suitable for most PA applications without the bulk of heavier gauge cables.

Use this cable to connect powered mixers or amplifiers with banana outputs to main PA speakers, floor monitors, or subwoofers equipped with Speakon inputs. It works well for small to medium venues, band rehearsal spaces, and mobile DJ setups where you need reliable connections between different connector types. The 20-foot length provides flexibility for stage layouts while maintaining signal integrity.

The cable comes ready to use with both connectors pre-installed and includes Seismic Audio's one-year warranty. Professional-grade construction at a practical price point makes this an essential cable for any sound system using mixed connector standards.

Frequently Asked Questions

What amplifiers and speakers work with this banana to Speakon cable?

This cable connects amplifiers or powered mixers with banana plug/binding post outputs to any speaker with Speakon inputs. Common applications include connecting older Crown, QSC, or Peavey amplifiers to modern PA speakers from brands like JBL, EV, or Seismic Audio. The cable works with any equipment using standard banana plugs and 1/4-inch Speakon connections.

Is 16-gauge wire sufficient for my PA system power requirements?

16-gauge cable handles most moderate power applications effectively, typically supporting amplifiers up to 500-800 watts depending on the run length and speaker impedance. For higher power systems over 1000 watts or longer cable runs, consider upgrading to 14-gauge or 12-gauge speaker cable. The 20-foot length of this cable works well within the power handling range of 16-gauge wire.

Can I use this cable for subwoofers or just main speakers?

This cable works for both main speakers and subwoofers, provided your power requirements stay within the 16-gauge capacity. Many powered subwoofers and monitor speakers use Speakon inputs, making this an ideal connection cable. For high-powered subwoofer systems over 800 watts, consider heavier gauge cable for optimal power transfer.

What venues or crowd sizes work best with this cable setup?

This cable length and gauge combination works well for small to medium venues accommodating 50-200 people, including clubs, churches, school auditoriums, and outdoor events. The 20-foot length provides good flexibility for stage layouts while the 16-gauge construction handles the power levels typically needed for these venue sizes without signal loss.

Do I need any adapters or additional cables with this purchase?

This cable comes complete with both connectors pre-installed and ready to use. No additional adapters are needed if your amplifier has banana plug outputs and your speaker has Speakon inputs. If your equipment uses different connector types, you'll need appropriate adapters or different cables to match your specific setup requirements.
