Neutrik speakON, splashproof IP54 , 4-pole , metal-, Soldering-female connector, silver plated contact(s), straight, max. 6 mm_, black

The Neutrik NLT4FXX-BAG is a premium, ultra-rugged 4-pole female speakON STXX Series cable connector featuring a black metal housing and solder terminations.

This connector is the direct, updated successor to the discontinued legacy NLT4FX-BAG model. It has been structurally re-engineered to achieve full compliance with modern global device safety standards (IEC 62368-1 and IEC 61984). It remains the industry baseline for heavy-duty, tour-grade amplifier-to-loudspeaker connections where standard plastic plugs risk being crushed by forklifts, trampled on stage, or exposed to harsh weather.

Key Technical Enhancements (FXX vs. Discontinued FX)

• IEC 62368-1 Safety Compliance: The internal contact insulation block and glass-reinforced structural elements have been updated to meet modern strict touch-proof and fire-retardant safety standards under high-wattage amplifier loads.

• Upgraded KTL Black Coating: The rugged zinc die-cast outer shell features an advanced black KTL (cathodic e-coat) and black-chrome finish. This ensures a non-reflective stealth profile on stage and highly improved scratch and corrosion resistance compared to older models.

Critical Design Features

• Heavy-Duty Solder Contacts: Instead of screw-clamp terminals found on standard plastic speakON lines, the STXX series features extra-large internal solder cups. Soldering creates an airtight, permanently stable physical bond capable of handling extreme low-frequency subwoofer vibrations without wires rattling loose.

• IP54 Weatherproof Barrier: The connector features a built-in rubber sealing gasket integrated into the metal housing. When mated to a matching companion STXX series panel plug, the connection achieves an IP54 rating, shielding the internal silver contacts against dust ingress and outdoor rain showers.

Technical Specifications Matrix

Operational Guardrail & Intermating Compatibility

• Cross-Compatibility: The NLT4FXX-BAG is fully backwards-compatible and will intermate seamlessly with standard 4-pole plastic speakON chassis connectors (such as the NL4MP and NL4MP-XX) as well as legacy STX metal inputs.

• The "Male Latch" Logic Shift: Note that in the premium metal STXX series, the locking release latch is located on the panel/chassis side rather than the cable connector shell itself.

• Strict Safety Warning: Although it is built with heavy-duty contacts and massive electrical headroom, the speakON architecture is strictly engineered for audio signal paths only. It must NEVER be used as an AC mains power supply connector.
