The Mogami GOLD SPEAKER SO-25 is a 25-foot speaker cable with speakON connectors at both ends. It is designed to connect a compatible amplifier or powered output to a passive speaker cabinet. This is a professional audio speaker cable, not an instrument, microphone, or line-level signal cable.
This cable is suited to musicians, sound engineers, rehearsal spaces, studios, and PA users who need a longer speaker-level connection with speakON terminations. Its 25-foot length can be useful when an amplifier and cabinet need to be positioned farther apart onstage or in a rack-based system. Confirm that both connected devices use compatible speakON connections and matching pin assignments.
The GOLD SPEAKER SO-25 uses four conductors of Mogami 2921 speaker cable. Its low-resistance, 14 AWG conductors are intended for speaker-level signal transfer between an amplifier and cabinet. The star-quad cable construction is designed to keep inductance low for a consistent connection over its full 25-foot run.
Mogami 2921 uses highly stranded bare NEGLEX oxygen-free copper conductors with color-coded PVC insulation. A flexible matte-black PVC outer jacket protects the internal conductors while supporting repeated setup and teardown. The completed cable uses 4-pole speakON connectors for locking amplifier-to-speaker connections.
Use the GOLD SPEAKER SO-25 where a speakON-to-speakON speaker run is needed between compatible equipment. It can fit bass, guitar, keyboard, studio-monitor, and professional PA speaker-cabinet applications when the equipment is designed for speaker-level speakON wiring. It is covered by Mogami's lifetime warranty.
Key Features
- 25-Foot Length: Provides extra reach for amplifier-to-cabinet speaker connections.
- speakON-to-speakON Ends: Connects equipment using compatible locking speakON ports.
- Mogami 2921 Cable: Uses Mogami's four-conductor studio speaker cable platform.
- 14 AWG Conductors: Uses 2.53 mm² conductors for low-resistance speaker wiring.
- Star-Quad Construction: Four-conductor layout is engineered for low inductance.
- Lifetime Warranty: Includes Mogami lifetime warranty coverage.
Design & Installation
The cable is built around four highly stranded bare NEGLEX oxygen-free copper conductors, each protected by PVC insulation. Its flexible PVC jacket has a matte-black finish, an 11.3 mm outside diameter, and color-coded internal conductors in brown, red, orange, and yellow. The cable is rated for use from -20°C to +70°C (-4°F to +158°F).
Connect one speakON end to a compatible amplifier or powered speaker output and the other to a compatible passive speaker cabinet input. Twist each connector until it locks, and route the cable to avoid pinching, sharp edges, and excessive strain. Verify connector pinout and speaker-load compatibility with the documentation for the amplifier and cabinet before powering the system.
