Introduction

Bi-wiring is a popular technique among audiophiles for improving the audio quality of speakers, as it allows for separate transmission paths for the high and low frequencies, reducing interference and enhancing overall sound clarity. The Furutech U-4.1T Speaker Cable is specifically engineered to excel in bi-wiring configurations, providing superior signal transfer, minimal signal loss, and exceptional performance. Its advanced design and high-quality materials ensure that your speakers receive a pure, accurate signal from your amplifier.

Key Features

1. High-Purity α (Alpha) OFC (Oxygen-Free Copper) Conductors
   • The U-4.1T features high-purity α (Alpha) OFC conductors, known for their superior conductivity and low resistance. These copper conductors undergo Furutech’s proprietary α (Alpha) cryogenic and demagnetization treatment, enhancing their conductivity and reducing internal stresses. This results in a more natural, detailed, and dynamic sound reproduction.
2. Dedicated Bi-Wire Design
   • The U-4.1T is specifically designed for bi-wiring applications, featuring separate conductor paths for high and low frequencies. This dedicated design reduces crosstalk and interference, ensuring that the audio signal remains clean and accurate, resulting in improved clarity, separation, and detail in your music.
3. Multi-Stranded Conductor Configuration
   • The multi-stranded design of the U-4.1T provides flexibility and excellent signal integrity. The carefully engineered strand structure minimizes skin effect and resistance, ensuring that the audio signal remains intact and unaltered, even over longer cable runs.
4. High-Quality Insulation and Jacket
   • The cable is insulated with a special polyethylene (PE) dielectric, which offers excellent electrical insulation properties. This insulation minimizes signal loss and interference, ensuring that your speakers receive a clean, accurate audio signal. The flexible and durable outer jacket allows for easy handling and installation in various setups.
5. Pure Transmission Technology
   • Furutech’s Pure Transmission Technology is applied throughout the U-4.1T, ensuring that every component is optimized for maximum signal transfer. This technology reduces signal loss, interference, and distortion, providing a more natural, transparent, and dynamic sound experience.

Benefits

• Enhanced Audio Clarity and Separation: The bi-wire design ensures that high and low frequencies travel separately, reducing interference and improving the clarity and separation of your audio signal. This results in a more detailed and dynamic listening experience.
• Superior Signal Transfer: The high-purity α (Alpha) OFC conductors and cryogenic treatment ensure that the U-4.1T delivers a clean, unaltered audio signal, allowing your speakers to reproduce sound with exceptional accuracy and fidelity.
