Sizing up

 
Unlike conventional audio cables, Townshend Audio Fractal™ and Isolda Speaker Cables are impedance-matched, eliminating the need for equal lengths to achieve optimal performance. Traditional non-impedance-matched cables require identical lengths to avoid phase or timing issues, which can waste money and space on unnecessary cable runs.
The Fractal™ and Isolda cables, designed with precision engineering, match the impedance of your speakers and amplifier, ensuring consistent signal delivery regardless of length differences. This saves costs by allowing shorter runs where possible and simplifies setup in space-constrained systems, all while maintaining exceptional clarity, dynamics, and soundstage. For best results, pair with the Townshend Allegri Reference and F1 Fractal™ interconnects.

.

Why match the nominal impedance of the amplifier to the speakers?

Matching the nominal impedance of the amplifier to the speakers ensures efficient power transfer, optimal performance, and minimal signal distortion. When the amplifier’s output impedance aligns with the speaker’s input impedance, the system delivers maximum power with a clean, undistorted signal, preserving dynamics, clarity, and frequency response. Mismatched impedances can cause signal reflections, power loss, or strain on the amplifier, leading to reduced sound quality, smeared transients, or even equipment damage. Using impedance-matched cables, like Townshend Audio’s Fractal™ and Isolda, further enhances this synergy, ensuring tight bass, articulate mids, and crisp highs for a superior listening experience.

Townshend Audio’s mechanical low pass filter exemplifies true decoupling, offering a level of vibration isolation that far surpasses conventional attenuation methods. By effectively isolating components from vibrations down to below 3 Hz, Townshend ensures that high-fidelity audio systems perform at their best, free from the distortions caused by external vibrations.

The Fractal Speaker Cable is our flagship audio solution, hand-crafted to deliver unmatched transparency and accuracy. It combines our proprietary Fractal-treated copper, impedance-matched geometry, and advanced vibration damping to elevate your listening experience beyond what standard cables can offer.

Unlike generic cables—often just basic wire in a fancy sleeve—the Fractal cable is built from first principles. It uses two Fractal-treated copper strips, impedance matching to reduce signal reflections, and a damped conduit to kill vibrations. The result? Tighter bass, a vivid 3D soundstage, and silence between notes that generic cables can’t match. Curious about the details? See this review: HiFi and Music Source.

It’s our proprietary process that enhances the copper’s conductivity and clarity—think of it as taking deep cryogenic treatment to the next level. We keep the specifics under wraps, but it’s what lets the Fractal cable reveal details and dynamics others miss.

Upgrading to the Fractal speaker cables takes the already exceptional Isolda design to new heights. The Fractal cables feature enhanced damping and vibration control thanks to a robust conduit surrounding the copper conductors, minimizing interference and noise. The proprietary Fractal treatment further refines the wire, reducing internal resistance and unlocking a new dimension of sound—reaching deeper into the silence between notes for unparalleled clarity and detail. If you’ve wondered how to improve upon near perfection, the Fractal cables deliver, offering a transformative listening experience.

Fractal F1 Speaker Cables: Precision Engineering for Pure Sound
Townshend Audio reimagines the original Isolda geometry with Fractal F1 speaker cables, embedding premium copper ribbons in synthetic silicone rubber to eliminate internal noise. This advanced design blocks external vibrations, keeping conductors stable for pristine audio clarity. Handcrafted over several days, each cable features precise conductor placement within a unique damping enclosure, paired with our exclusive Townshend Audio Fractal treatment. This non-directional cable delivers unrivalled sound quality.

How the F1 Fractal Speaker cable was born

The F1 Fractal™ Speaker Cables and Isolda Interconnects advance Shin Edo’s 1979 impedance-matched design, lauded by Max Townshend as the “holy grail” for pure sound. By eliminating micro-reflections, they deliver deep bass, clear mids, and sparkling treble. Backed by Max’s research, these precision cables redefine hi-fi excellence where you may hear detail within detail- Fractal Sound

The Sound of Music and Error in Your Speaker Cables

Max Townshend’s research paper, “The Sound of Music and Error in Your Speaker Cables,” investigates how speaker cable geometry affects audio quality by measuring signal reflections caused by impedance mismatches. Using a computer spectrum analyzer, Townshend tested various cable designs, finding that non-impedance-matched cables produce micro-reflections—seen as “ringing” on oscilloscopes—that smear transients, brighten sound, and veil clarity. His Isolda and F1 Fractal™ cables, with closely spaced ribbon conductors, achieve a near-flat frequency response (close to 8-ohm speaker impedance), minimizing reflections for pure, undistorted sound. This work, validated by listening tests, underscores why impedance-matched cables outperform others, especially for complex music
Analysis

Townshend Audio Fractal-Wire™ Technology

Fractal-Wire™ is Townshend Audio’s cutting-edge conductor technology, delivering zero-distortion audio signal transfer for unparalleled sound purity. Surpassing our renowned Enhanced Deep Cryogenic Treatment (EDCT), the proprietary Fractal™ treatment process reduces the electrical resistance of 99.99% pure copper by up to 10%, ensuring transparency even over long runs, like the 290 meters in each channel of the Allegri Reference Preamplifier. Compared to untreated copper (dull, lacking dynamics), silver (steely, thin), or EDCT copper (detailed but less sparkling), Fractal-Wire™ offers unmatched clarity and detail without grain or hardness.
Used in F1 Fractal™ interconnects, Isolda impedance-matched speaker cables, speaker driver coils (9m per driver), turntable arm wiring, microphone cables, and transformers, Fractal-Wire™ consistently enhances sound quality. Listeners report vivid, natural audio with deeper layers and precise musicality, making it ideal for high-fidelity systems. Pair with the Allegri Reference for a transformative listening experience.
