Reference Loudspeaker Performance in the Norse 2 Series | Available at Trimira Audio
The Nordost Heimdall 2 Speaker Cable is the entry point to Nordost's Norse 2 Series, combining the company's distinctive flat-ribbon geometry with silver-plated solid-core conductors, FEP insulation, and Micro Mono-Filament technology.
Designed to minimize unwanted electrical interaction and maintain a controlled low-loss signal path between amplifier and loudspeaker, Heimdall 2 is suited to demanding two-channel systems where transient precision, dynamic scale, and spatial resolution are priorities.
At Trimira Audio, we recommend the Heimdall 2 Speaker Cable for high-performance floorstanding and bookshelf loudspeakers, including systems configured for single-wire, bi-wire, or bi-amp operation.
Key Features & Proprietary Technologies
Flat Ribbon Extrusion Geometry
Nordost's characteristic flat-ribbon construction arranges the conductors in parallel rather than bundling them into a conventional round cable.
This geometry is designed to control:
- Conductor interaction
- Capacitance
- Inductance
- Electromagnetic coupling
- Dielectric interaction
Proprietary Micro Mono-Filament Construction
Each conductor is individually spiral-wrapped with a fine FEP filament before the outer FEP jacket is applied.
The resulting low-contact dielectric environment is designed to reduce dielectric interaction and energy storage.
18 Silver-Plated Solid-Core Conductors
Heimdall 2 employs 18 × 22 AWG solid-core conductors manufactured from high-purity OFC copper with pure silver plating.
The solid-core architecture maintains consistent conductor geometry without the strand interaction associated with conventional multi-stranded speaker cables.
High-Purity FEP Insulation
Each conductor is insulated with Fluorinated Ethylene Propylene (FEP), providing a low-loss dielectric environment with high mechanical and thermal stability.
Mechanically Tuned Spacing & Lay
Precision-controlled conductor spacing helps maintain consistent electrical geometry while managing mechanical resonance and high-frequency electrical characteristics.
Precision Hand Terminations
Heimdall 2 can be terminated with gold-plated:
- Z-plug banana connectors
- Standard 6.5 mm spades
- Large 8.5 mm spades
It is available in Shotgun, Bi-Wire, and Bi-Amp configurations.

Shotgun, Bi-Wire & Bi-Amp Options
Shotgun
A conventional stereo-pair configuration for loudspeakers using a single set of binding posts.
Bi-Wire
Separate cable runs connect the amplifier to the loudspeaker's high- and low-frequency terminals, where supported by the loudspeaker.
Bi-Amp
Separate amplifier channels can drive the loudspeaker's high- and low-frequency sections where the loudspeaker and amplification system support this configuration.
Trimira Audio can help determine which configuration best matches your amplifier and loudspeaker architecture.
