Clarus Crimson MKII Single-Wire Speaker Cable

Reference-level speaker cable engineered for maximum transparency, dynamics, and signal integrity.

The Clarus Crimson MKII Single-Wire Speaker Cable is Clarus' reference speaker cable, combining 10 AWG Pure Continuous Cast Copper (PCCC) conductors with specialized geometries engineered independently for bass, midrange, and high-frequency transmission.

Rather than using one conventional conductor throughout the cable, Crimson employs multiple solid bass conductors, a dedicated flat midrange conductor, and multiple spiral-ribbon high-frequency conductors. Clarus combines these with individually insulated conductors, a flat parallel cable architecture, sophisticated internal twisting, and MKII Spring Tension connectors to create an extremely low-loss connection between amplifier and loudspeaker.

10 AWG PCCC Copper Construction

Crimson uses Pure Continuous Cast Copper (PCCC) throughout its substantial 10 AWG conductor architecture.

The continuous-casting process produces long lengths of highly pure copper with minimal crystal boundaries, low electrical resistance, and excellent structural consistency.

For a reference speaker cable, the objective is to preserve the amplifier's signal with minimal resistance, interference, and alteration before it reaches the loudspeaker.

Frequency-Optimized Conductor Geometry

Clarus does not treat every part of the audio spectrum identically.

The Crimson architecture uses different conductor shapes according to their frequency role:

Bass: Multiple solid conductors provide substantial cross-sectional area for low-frequency energy and current delivery.

Midrange: A dedicated wide, flat conductor is optimized for the critical mid-frequency region.

High Frequencies: Multiple spiral-ribbon conductors provide a specialized low-mass path for high-frequency information.

By mathematically balancing these different geometries, Clarus designed Crimson to maintain clarity, tonal balance, transient detail, and dynamic consistency across the audible spectrum.

Multi-Stage Alternating Twist Architecture

Inside Crimson, conductor geometry becomes even more sophisticated.

Individual conductors are selectively twisted according to their frequency role, while counter-rotational core twisting is used to reduce induced distortion.

This multi-stage alternating twist architecture is designed to minimize magnetic-field interaction while helping time-align frequency propagation through the cable.

It is a significant part of what separates Crimson from a conventional large-gauge speaker cable.

Flat Parallel Cable Architecture

Crimson positions its positive and negative conductor groups in a flat parallel configuration rather than simply twisting the two sides together.

Clarus developed this geometry to minimize phase distortion and maintain more consistent signal propagation between the amplifier and loudspeaker.

Combined with the cable's large 10 AWG conductor area, the architecture also provides low electrical resistance for demanding high-current loudspeaker systems.

Individually Insulated Conductors

Every conductor within Crimson is individually insulated using precision-formulated polyethylene (PE).

Separating the individual conductors helps minimize interaction between them while maintaining the intended electrical behavior of the specialized bass, midrange, and high-frequency geometries.

The insulation system is therefore part of the cable's overall electrical design rather than simply an outer protective layer.

MKII Spring Tension Connectors

Crimson MKII can be terminated with BFA banana plugs, spade lugs, or a combination of the two.

Clarus manufactures its connectors from military-grade beryllium copper, selected for its conductivity, mechanical strength, and ability to maintain spring tension.

The MKII BFA banana compresses when inserted into a binding post to create 360-degree electrical contact. Its beryllium-copper construction continuously applies outward pressure to maintain the connection.

The MKII spade uses a machined center section that allows the terminal to flex under pressure. As the binding post is tightened, the inherent spring tension of the beryllium copper helps maintain a secure long-term connection.

Built for Reference Audio Systems

Crimson is designed for systems where the speaker cable should preserve the resolution and dynamic capability of reference electronics and loudspeakers.

Its combination of substantial conductor gauge, PCCC metallurgy, frequency-specific conductor geometry, controlled twisting, individual insulation, and low-loss terminations makes it particularly appropriate for highly resolving two-channel systems and demanding loudspeaker loads.

Technical Specifications

Important: Clarus packages Crimson single-wire speaker cables individually rather than as stereo pairs. A standard two-channel system requires two cables.
