Speaker Terminal Adapter

This 70 mm by 28 mm board provides four spring-loaded pin positions for speaker cable termination. It suits installers and hobbyists building or repairing custom speaker cabinets who need a reliable screwless connection method. The pack contains twenty-five pieces for multi-driver projects.

Replaces Soldered or Screw Terminals

The push-type spring load design removes the need for soldering irons or screwdrivers during assembly. The upgrade is worth it when frequent driver changes or rapid prototyping are required, because wires can be inserted and released in seconds without tooling. Mounting holes spaced at 60 mm simplify panel layout.

Sustained Connection Stability

Spring pressure maintains consistent contact resistance over long periods, reducing the risk of intermittent signals caused by vibration or thermal cycling. The 22 mm overall height keeps the board clear of internal bracing in typical enclosures. No active cooling or power circuitry is involved, so thermal performance is not a factor.

Questions about this item

Will the 60 mm mounting-hole spacing and 3.3 mm hole diameter fit my enclosure?

The adapter has two mounting holes spaced 60 mm apart, each 3.3 mm in diameter.

How do I insert the speaker wire into the spring-loaded terminals without damaging the clamp?

Press the spring tab down with a small screwdriver, insert the stripped wire, then release the tab to lock it in place.

When should I replace these terminal boards in a speaker cabinet?

Replace a board if the spring tabs lose tension, the metal contacts show corrosion, or the plastic housing cracks from heat or vibration.
