Furutech DSS-4.1 Uses α-OCC + α-DUCC Hybrid Conductors for Reference-Grade Signal Purity
Furutech DSS-4.1 Reference α-OCC/α-DUCC Speaker Cable (per metre) is a high-performance, 11AWG speaker cable designed for uncompromising audio reproduction in premium stereo and multichannel systems. Engineered with a hybrid blend of Furutech’s Alpha-OCC and α-DUCC (7N class) copper, this reference-grade cable preserves signal integrity with exceptional clarity, dynamic control, and tonal balance.
The unique conductor formulation combines Pure Transmission α-OCC — copper processed through Furutech’s proprietary cryogenic and demagnetising treatments — with DUCC Ultra Crystallized High-Purity Copper, developed in partnership with Mitsubishi Materials. This combination offers both large-grain continuity and precision crystal alignment, dramatically reducing internal electrical resistance and transmission distortion. With DUCC’s advanced lattice structure, the signal path remains smooth and directionally stable, making the DSS-4.1 ideal for long cable runs and high-current speaker applications.
Multi-Layer Spiral Construction Improves Electrical Coherence and Mechanical Control
Furutech DSS-4.1 speaker cable uses a complex, multi-layered spiral geometry to enhance phase coherence and eliminate resonance. Three distinct conductor zones, each with tightly controlled strand gauge and rotational direction, are concentrically arranged around a stabilising core. This design not only balances mechanical tension but also reduces crosstalk and time-domain smear, allowing music to emerge with exceptional focus and dimensionality.
Internal twisting of the dual conductors ensures minimal electromagnetic interference and controlled inductive behaviour, while the layered construction dampens mechanical vibration. In high-resolution systems, this translates to improved imaging, tighter bass articulation, and effortless treble extension — particularly evident in systems with revealing transducers or valve amplification.
Advanced Dielectric and Shielding System Ensures Ultra-Low Noise Floor
Furutech DSS-4.1’s insulation architecture is crafted from premium-grade fluoropolymer and polyethylene materials selected for their low dielectric constant and high thermal stability. This ensures consistent capacitance and superior electrical isolation throughout the cable length. Combined with robust internal shielding, including copper foil and high-coverage OFC braid, the cable effectively rejects EMI and RFI from power sources and nearby signal lines.
To further refine performance, Furutech incorporates barrier wraps, vibration-damping fillers, and a flexible yet durable inner sheath infused with nano-ceramic and carbon particles. This internal shielding matrix provides outstanding control over stray currents and microphonic pickup, preserving the cable’s black background and dynamic resolution.
Audiophile-Grade Outer Construction Offers Flexibility and Aesthetic Sophistication
Furutech DSS-4.1 is encased in a rugged, aesthetically refined outer jacket, finished in deep purple PVC and wrapped with a black/silver nylon braided sleeve. Though substantial in diameter, the cable maintains installation flexibility, making it suitable for complex rack systems or full-length runs to floorstanding loudspeakers. The outer layers are not only visually striking but also contribute to long-term durability, resistance to abrasion, and reduced mechanical stress on the internal conductors.
Designed for those who demand the purest possible signal path between amplifier and speaker, Furutech DSS-4.1 Reference α-OCC/α-DUCC Speaker Cable delivers immersive realism, microdynamic detail, and tonal neutrality in a form tailored for high-end audio systems. Its meticulous material selection, layered construction, and cryogenic processing reflect a no-compromise approach to cable design — one that prioritises sonic truth above all else.
