Furutech Speaker Reference III High End Perfomance Speaker Cable (3 or 2 m / pair)

Price range: 1 912.86€ through 249 302.40€

The Furutech Speaker Reference III is a premium high-end speaker cable pair designed to deliver a more transparent, controlled, and spatially stable connection between your amplifier and loudspeakers. Built with Furutech’s “Pure Transmission” philosophy—high-purity metallurgy, mechanically stable construction, and precision terminations—it targets lower noise, better separation, and stronger bass grip without adding glare or thinning…

Description

A reference speaker cable must do two things at once: preserve micro-detail and imaging while also letting the amplifier maintain real control of the loudspeaker load—especially during transient peaks. The Furutech Speaker Reference III is designed for systems where the last link (amp → speakers) must remain calm, stable, and tonally natural, even as current demand rises.

Built for coherence, separation, and bass control

In revealing systems, speaker cables can change perceived bass articulation, timing, and the “structure” of the soundstage. A truly refined cable improves control and separation rather than simply boosting treble energy. Speaker Reference III is aimed at:

  • A lower perceived noise floor (blacker background)

  • More stable image focus and depth layering

  • Tighter, better-defined low frequencies

  • A cleaner sense of attack and decay on instruments

  • A more coherent tonal balance from top to bottom

Pure Transmission approach: metallurgy + contact integrity

Furutech’s design philosophy focuses on what matters electrically and mechanically:

  • High-quality conductor material and consistent strand structure

  • Rigorous attention to connector quality and contact pressure

  • Mechanical stability to reduce micro-resonance and vibration effects

  • Reliable terminations that don’t loosen or oxidize quickly

In real-world terms, this is the difference between a cable that sounds impressive for a short demo and a cable that keeps the system sounding composed over long listening sessions.

Termination options: standard and BW variants

The model codes you listed indicate different termination configurations:

  • Speaker Ref. III-06: typically the 3.0m pair (common Furutech naming convention for “06” = 3m pair; confirm with your distributor sheet).

  • Speaker Ref. III-04-BW: typically the 2.0m pair, BW termination variant.

  • Speaker Ref. III-06-BW: typically the 3.0m pair, BW termination variant.

In practice, BW often indicates a specific termination set (commonly banana/wire or banana-related configuration), while the non-BW version is often spade-terminated. Because exact meanings can vary by market, it’s best to list the terminations explicitly in WooCommerce (e.g., Banana–Banana, Spade–Spade, etc.).

Where it fits best in a system

Speaker Reference III is ideal for:

  • High-resolution integrated amps and power amps where current delivery and damping factor matter

  • Loudspeakers that reveal changes in bass control and image precision

  • Systems that already have good source and amplification but feel slightly “flat,” “soft,” or “hazy”

  • Setups where you want more clarity and control without pushing the treble forward

If your system is sensitive to brightness, prioritize correct speaker placement and room treatment; then use a reference cable like this to improve stability and low-level definition without adding glare.

Setup tips for best results

  • Use the shortest practical length (2m if your rack layout allows it).

  • Keep left and right cable runs similar in routing and distance from power cords.

  • Ensure your speaker terminals and amp binding posts are clean and firmly tightened.

  • If using bananas, confirm a tight fit; if using spades, confirm correct fork size and torque.

RATING

High End Performance Speaker Cable for Audio Equipment

All metal parts are treated with the
※FURUTECH α(Alpha) Process (Super Cryogenic & Demagnetizing Treatment)

FEATURES

Top of the line double-shielded α (Alpha)-OCC conductor interconnects, power cords and digital cables featuring extraordinary build quality and Formula GC-303 antimagnetic EMI-absorbent modules surrounding the cable offering greater resolution, more powerful dynamics, and virtuoso performances from all your components. All connectors are rhodium-plated for optimal signal transfer.

” Furutech might rightly be thought of as WBT’s elder Japanese brother. Elder and bigger …
Shielding from and against noise pollution in cables has become more important than ever – and Furutech has developed a very powerful yet elegant antidote … Bravo.”

Features:
•Double-shielded α (Alpha)-OCC Conductors eliminate radiated noise
•Formula GC-303 Antimagnetic EMI-Absorbent Modules surround each cable
•High performance beautifully engineered and finished rhodium plated pure copper spades
•FP-201 (R) Spade terminals nonmagnetic rhodium-plated pure copper (Nonmagnetic rhodium-plated eutectic cast brass FP-202 (R) Banana connectors by request).
•Insulated with air-foamed Irradiated PE reducing capacitance and damping vibration
•Results in greater resolution, clarity, powerful dynamics, and an ultra-quiet soundstage in which music develops more fully without artificial upper-frequency “presence region” glare.
•GC-303 allows a deeper, tighter bass to form a solid foundation for the rest of the frequency range, better defining the original recording’s venue. Natural, unforced detail reveals nuance and energy for an engaging musical experience.

Here’s What The Critics Say
“The Furutech cable sound is easily described as one that completely avoids those peculiar striations that result from highlighting, the providence of certain silver cables that emphasize edge definition for nearly surreal image lock. Such sharp edging then becomes synonymous with etching. It gives a short-lived appearance of exceptional detail – short-lived since such sound is not only unrealistic but fatiguing.

“The Furutech cables patently don’t cause this. However, they are exceptionally detailed.
I can’t help but think that the hexagonal barrel innards [Formula GC-303 Modules] are at least somewhat responsible for this wealth of clearly intelligible inner detail. Rather than throwing detail at you, they throw out inter-note noise. While the end result might seem the same — more detail — the way it communicates is very different. Put plainly, the Furutechs never fatigue even at elevated levels yet they do remain ultra resolved.”
