The FS20 speaker cable delivers reliable signal transmission for connecting power amplifiers to passive PA speakers, guitar amplifier heads to cabinets, and mixing consoles to powered monitors. Built with 14-gauge, 2-conductor wire and PVC jacketing, this cable maintains signal integrity across demanding live sound applications.

This 20-foot cable handles the power demands of most PA systems while providing enough length for stage setups where amplifiers need to sit away from speakers. The 14-gauge wire construction ensures minimal signal loss even at higher power levels, while the durable PVC outer jacket protects against wear from repeated setup and teardown.

Each cable terminates in mono 1/4" connectors that fit standard speaker outputs and inputs found on power amplifiers, passive speakers, and guitar amplifier heads. The black cable construction keeps stage aesthetics clean and professional. At 20 feet, the FS20 provides the reach needed for most small to medium venue configurations without excess cable creating stage clutter.

Common applications include connecting power amplifiers to main PA speakers in venues up to 200 people, linking guitar amplifier heads to speaker cabinets, and running signals from mixing consoles to stage monitors. The cable works with any equipment featuring 1/4" speaker connections, from club PA rigs to church sound systems.

Setup requires no adapters or additional cables - simply connect the 1/4" plugs directly to your amplifier output and speaker input. Each FS20 cable includes Seismic Audio's one-year warranty and ships ready for immediate use in your live sound rig.

Frequently Asked Questions

What gauge wire do I need for speaker cables?

14-gauge wire like the FS20 handles most live sound applications effectively. This gauge provides low resistance for power transfer while remaining flexible enough for repeated setup. For very high-powered systems over 500 watts RMS or runs longer than 25 feet, consider 12-gauge cables, but 14-gauge works well for typical club and church PA systems.

Can I use this cable to connect my amplifier head to a speaker cabinet?

Yes, the FS20 works perfectly for connecting guitar or bass amplifier heads to speaker cabinets. The 1/4" mono connectors match the speaker outputs on most amplifier heads and the inputs on guitar speaker cabinets. The 14-gauge wire handles the power output of tube and solid-state amplifier heads without signal degradation.

How long of a speaker cable do I need for a small venue setup?

For venues up to 200 people, 20-foot cables like the FS20 typically provide enough length to position amplifiers at the side or back of the stage while reaching main speakers placed at the front corners. This length also works well for guitar rigs where the amplifier head sits on stage but the speaker cabinet is positioned for better sound projection.

What's the difference between speaker cables and instrument cables?

Speaker cables like the FS20 use thicker wire gauges (14 AWG) to carry amplified signals from power amplifiers to speakers without power loss. Instrument cables use thinner wire and are designed for low-level signals from guitars or microphones to amplifiers or mixing consoles. Using an instrument cable as a speaker cable can cause signal loss and potential damage.

Will this cable work with powered speakers?

No, the FS20 is designed for connecting amplifiers to passive speakers that require amplified signals. Powered speakers typically use XLR or 1/4" TRS inputs for line-level signals from mixing consoles or audio interfaces. For powered speakers, you'll need standard audio cables rather than speaker cables like the FS20.
