The B12SP35 connects powered amplifiers with banana plug outputs to passive speakers with Speakon inputs, bridging the gap between older and newer pro audio gear. This 35-foot cable handles the power demands of live sound reinforcement, DJ setups, and installed sound systems where you need reliable signal transfer across longer distances.

Built with 12-gauge, 2-conductor wire, this cable delivers consistent power transmission for high-wattage applications without signal degradation. The heavy-duty construction uses shielded PVC jacketing that stands up to repeated setup and teardown cycles common in mobile sound reinforcement.

The 12-gauge wire thickness ensures minimal power loss over the 35-foot run, making it suitable for driving main PA speakers, floor monitors, and subwoofers in medium to large venues. Gold-plated banana plugs provide secure binding post connections, while the locking Speakon connector ensures your speaker stays connected during performances.

Perfect for connecting vintage amplifiers to modern PA speakers, this cable works in churches upgrading their sound systems, bands mixing old and new gear, and venues with established amplifier racks feeding newer speaker systems. The 35-foot length covers most stage-to-audience distances without requiring extensions.

Simply connect the banana plugs to your amplifier's binding posts and lock the Speakon connector into your speaker's input. The cable's flexibility makes routing through cable management systems straightforward.

Seismic Audio backs this professional-grade speaker cable with a one-year warranty, and it ships ready to use in demanding live sound environments.

Technical Specifications

Frequently Asked Questions

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

This cable connects any amplifier with banana plug outputs (binding posts) to passive speakers with Speakon inputs. It's commonly used with vintage or entry-level amplifiers that lack Speakon outputs, connecting them to modern PA speakers, monitors, or subwoofers that use Speakon connectors for reliable power handling.

How much power can this 12-gauge cable handle safely?

The 12-gauge wire construction safely handles high-power applications typically found in live sound reinforcement. This gauge is suitable for most amplifiers driving passive speakers in venues up to 500 people, ensuring minimal power loss and heat buildup over the 35-foot cable run.

Do I need this cable if my amplifier already has Speakon outputs?

No, if your amplifier has Speakon outputs, use a standard Speakon-to-Speakon cable instead. This banana-to-Speakon cable specifically solves the compatibility issue when you have older amplifiers with only binding post outputs that need to connect to modern speakers with Speakon inputs.

Will 35 feet cause signal loss or affect sound quality?

The 12-gauge wire minimizes signal loss over 35 feet, maintaining consistent power delivery to your speakers. This length is well within acceptable limits for professional audio applications, and the heavy-duty construction ensures reliable performance without introducing noise or power degradation.

Can I use this cable for both main speakers and monitors?

Yes, this cable works for any passive speaker connection where you need to go from banana plugs to Speakon. Whether connecting main PA speakers, floor monitors, or subwoofers, the 12-gauge construction and 35-foot length handle the power requirements and distances typical in live sound setups.
