Speaker Terminal Overview

This two-pack provides spring-loaded speaker terminals for custom speaker builds or upgrades. Each unit uses a push-type design that accepts bare wire through a 5 mm hole. The red and black colour coding simplifies polarity identification during installation. Two pieces are included for stereo or multi-channel setups.

Mounting and Connection Details

Terminals measure 57 mm by 57 mm by 31 mm overall with an 18 mm by 3.5 mm screw footprint and a 4 mm mounting hole diameter. The spring mechanism holds wires securely without soldering or screw tightening. Black plastic housing blends into speaker cabinets. No tools are required beyond a screwdriver for panel mounting.

Sustained Use Behaviour

Under continuous signal the spring pressure maintains consistent contact resistance without loosening. The passive design generates no heat and draws no power, so performance remains stable during extended listening sessions. Mechanical fatigue is minimal because the spring only deflects during wire insertion and removal.

Questions about this item

How do I install the 57mm spring speaker terminal board into a speaker cabinet?

Cut a 57mm square opening in the cabinet panel, insert the terminal board through the front, and secure it with four 4mm mounting screws through the corner holes.

What maintenance or replacement will the spring-loaded wire terminals need over time?

The spring mechanism maintains tension indefinitely; only replace a terminal if the plastic housing cracks or the metal contacts show visible corrosion.

What is the maximum wire gauge that fits the 5mm inner-diameter wire holes?

The 5mm holes accept bare wire up to roughly 4 mm² cross-section; thicker conductors will not insert fully and may damage the spring clips.
