These SASPT12-50 speaker cables connect powered mixers, amplifiers, and rack gear to passive PA speakers and monitors that use 1/4" inputs. The two-cable pack gives you matching runs for stereo setups or backup cables for critical shows.

Built with 12-gauge conductors, these cables handle high-power applications without signal loss or overheating. The heavy-duty construction supports the current demands of modern amplifiers pushing serious wattage to your mains and monitors.

Each 50-foot cable features a locking Speakon connector on one end and a 1/4" TS male plug on the other. The 2-conductor design with shielded PVC jacket protects against interference while maintaining signal integrity across longer cable runs. This gauge and length combination works well for permanent installations and touring rigs alike.

Perfect for live sound engineers running power from rack-mounted amplifiers to floor monitors, or connecting powered mixers to passive PA speakers in medium to large venues. The 50-foot length covers most stage-to-FOH distances and allows flexible speaker placement for outdoor events and festival stages.

The Speakon end connects to professional amplifiers and powered mixers with Speakon outputs, while the 1/4" end plugs into passive speakers and monitors with standard phone jack inputs. Both cables come ready to use straight from the package.

Seismic Audio backs these speaker cables with a one-year warranty and ships them fast. Professional-grade construction at a price point that makes sense for working musicians and sound companies.

Technical Specifications

Frequently Asked Questions

What's the difference between 12-gauge and 14-gauge speaker cables?

The 12-gauge cables in this pack handle more current without voltage drop, making them better for high-powered amplifiers and longer cable runs. The thicker conductors reduce resistance and heat buildup when pushing serious wattage to your speakers.

Can I use these cables to connect my powered mixer to passive PA speakers?

Yes, if your powered mixer has Speakon outputs and your passive speakers have 1/4" inputs. The Speakon end connects to your mixer's speaker outputs, while the 1/4" end plugs into your passive speakers. This is a common setup for many live sound applications.

How much power can these 50-foot cables handle safely?

The 12-gauge conductors support the power output of most professional amplifiers without signal degradation or overheating. The exact power handling depends on your amplifier's output and speaker impedance, but these cables won't be the limiting factor in typical live sound setups.

Are 50-foot cables too long for a small venue setup?

Not at all - longer cables give you flexibility in speaker placement and room for growth. Extra cable length doesn't hurt audio quality with these shielded 12-gauge cables. You can always coil up excess length, and having longer cables means you won't get caught short when you need more reach.

Do these work with both 4-ohm and 8-ohm speakers?

Yes, speaker impedance doesn't affect cable compatibility. These cables pass the signal from your amplifier to any passive speaker with a 1/4" input, regardless of the speaker's impedance rating. The amplifier and speaker determine the impedance match, not the cable.
