These dual speakon and dual 1/4" jack plates are essential components for DIY speaker builders, repair technicians, and venue operators who need reliable connection points for PA speakers and monitor cabinets. Each metal jack plate provides four total connection options, giving you maximum flexibility for different cable types and backup connections.

The 4 1/2" x 6 1/4" black metal construction handles the rigors of live sound environments while providing secure, stable connections for both professional speakon cables and standard 1/4" instrument cables. The dual configuration means you can run parallel connections or have backup inputs ready when needed.

Installation requires a 3 3/8" x 5 1/8" cutout in your speaker cabinet, making these plates compatible with most standard PA speaker designs. The metal construction resists wear from frequent cable changes and provides proper grounding for your connections.

Perfect for custom speaker builds, replacing damaged jack plates on existing cabinets, or upgrading older speakers with outdated connection options. Sound engineers often use these when building monitor wedges or side-fill speakers that need both professional speakon connections and standard 1/4" compatibility for different venues and mixing consoles.

You get two complete jack plates with all necessary hardware. No additional connectors or wiring included - you'll need to supply your own wire and solder connections based on your specific cabinet design.

Each jack plate comes with Seismic Audio's one-year warranty and ships ready to install in your next cabinet project.

Frequently Asked Questions

What size cutout do I need in my speaker cabinet?

You'll need to cut a rectangular hole measuring 3 3/8" x 5 1/8" in your speaker cabinet. The jack plate itself measures 4 1/2" x 6 1/4" on the outside, so it will overlap the cutout by about 1/2" on all sides for a secure mount.

Do these jack plates come with the internal wiring connections?

No, these are just the metal jack plates with the connector housings installed. You'll need to supply your own wire and make the solder connections between the jack plate terminals and your speaker drivers or crossover network based on your specific cabinet design.

Can I use both speakon and 1/4" inputs at the same time?

Yes, you can wire both connector types in parallel to give yourself maximum flexibility. This is common in professional installations where you might need speakon connections for main PA feeds but want 1/4" backup options for different mixing consoles or amplifier types.

Are these suitable for high-power PA applications?

These jack plates use standard speakon and 1/4" connectors that can handle typical PA power levels. The metal construction provides durability for frequent cable changes in live sound environments. However, your power handling will ultimately depend on your internal wiring gauge and speaker components.

What tools do I need to install these jack plates?

You'll need a jigsaw or router to cut the rectangular opening, a drill for mounting screw holes, and basic soldering equipment to connect your internal wiring to the jack plate terminals. Standard hand tools will handle the mounting hardware installation.
