Seismic Waves

What is it that distinguishes the sound of a great hi-fi system from a merely good one? Is it how loud it will go? Does it depend on the amount of bass energy it can pump into your listening room? Is it something to do with pace, rhythm and timing or what hi-fi reviewers sometimes refer to as the sound being ‘fast’? These are a few audible characteristics among many. Some can be emphasised or attenuated to alter the sound, and there any number of cable and ‘accessory’ manufacturers out there that will help you achieve such an ‘effect’, some arguably desirable, some less so. Either way, and however beneficial the changes might seem, they are most likely benign distortions, and minimising distortion, in all its forms, is a principal goal of hi-fi. Only then will a true sense of realism be won.
So here’s the sobering fact. Every hi-fi system, from humble to high-end, has its performance ceiling set not by the cost and quality of its individual components but by how completely those components – the source, the amplification, the loudspeakers – are isolated from the world around them. And when we say ‘world’ we mean that literally, as we’ll explain in a moment.
Vibration.
Without it, we wouldn’t hear a thing. Yet, as interference, it can destroy the realism – critically realised in the finest, low-level detail – of the music we love. The aim, therefore, is to preserve the good vibrations (something worth signing about as the Beach Boys would no doubt agree) by preventing contamination from the bad ones.
This used to be thought of as a singularly circular problem. That is, it was all the fault of the loudspeaker, as it was both the means for converting electrical signals into the vibrations we perceive as music and (because it was physically coupled to the room in which it was being played), also the culprit for resonant interference – not only to the detriment of its own performance but also everything else in the playback chain.
Nothing much has changed in this respect. If unchecked these unwelcome resonances are a fundamental cause of under-achieving sound quality, and well recognised as such – to the extent that, over the years, the burgeoning ‘isolation’ business has spawned myriad ‘solutions’ to the problem, ranging from the widely favoured spiked speaker stands and equipment racks to simple, cushioning elastomers and, more recently, exotic, expensively-encased ceramic balls with mysterious ‘energy-draining’ properties. We wouldn’t dispute that they all do something to change the sound – maybe enough, in some cases, to persuade the listener that unwanted vibrations have been vanquished and all is well with the world. It isn’t.
Microtremors.
Any group of components brought together with the aim of accurately reproducing music or a film soundtrack is at the mercy of our planet, and the consequences truly are seismic. Every moment of the day and night, global activity is occurring, mostly manifested as a phenomenon known as microtremors. These ground-borne seismic vibrations are always present, everywhere, all the time. They are Mother Earth’s never-ending backing track, the residual noise recorded on seismographs between earthquakes. Unless filtered out, the microtremors join in and wash away crucial fine detail.
So how come we can’t feel them? Their amplitude is very low, measuring between force -1 and force 2 on The Richter Scale, as shown (fig. 1) from the US Geological Survey. No, you can’t feel them and the only way you can see them is as a graphic trace. But you can hear their degrading influence. The presence of low-level seismic activity 24/7 is responsible for undermining your hi-fi’s potential to give true musical satisfaction and ultimately compromises your financial investment in whatever hardware you own or choose to own.
The solution.
Townshend Audio is the world’s only manufacturer of isolation systems that protect hi-fi and AV equipment from seismic microtremors. The first line of defence is the Seismic Podium. Designed as a range to accommodate any size and weight of speaker – standmount plus stand, floorstander or subwoofer – the Seismic Podium breaks the acoustic connection between the floor and the speaker, preventing the passage of deleterious vibrations both to and from the speaker cabinets. For a detailed explanation of why this is an absolute necessity before any speaker can perform to its true potential, read ‘Earthquakes on hi-fi’, http://goo.gl/sv3GsX.

Why Choose Isolda Speaker Cables?


Most speaker cables in the audio industry overlook the science of transmission line theory, resulting in micro-reflections that smear and veil the purity of sound. These reflections bounce between the source and speaker, muddying the music you love. The Isolda DCT Speaker Cable eliminates this issue through its unique geometry, closely matching the impedance of your amplifier and speakers. The result? A crystal-clear soundstage, lifelike 3d imaging, and seismic bass that transforms your listening experience.

Engineered for Audiophile Perfection

Crafted by hand in small batches, Townshend Isolda cables feature closely spaced, insulated flat copper conductors encased in a polyester braid sheath. This design makes them virtually immune to Radio Frequency Interference (RFI), ensuring a silent background that lets every note shine. Whether you’re listening to intricate classical compositions or powerful rock anthems, the Isolda delivers sound so natural, it feels like the artist is in the room.

Pure, Uncolored Sound

 

The Isolda DCT’s impedance-matched design (8 ohms) eliminates signal reflections, delivering music exactly as recorded. The Ear praises it as “one of the best speaker cables money can buy” for its neutral, fatigue-free sound.

Seismic Bass Power

Closely spaced EDCT copper ribbons produce deep, articulate bass with unrivaled solidity. townshendcable.com highlights “bass with a power that is truly seismic,” making every low note punchy and precise.

Stunning 3D Imaging

he cable’s low-inductance geometry creates a holographic soundstage, placing instruments with pinpoint accuracy. 6 Moons notes it “can convey a huge and realistic soundstage,” immersing you in the music.

 

 

 

Silent Backgrounds

 

Virtually immune to RFI due to its flat, closely spaced conductors, the Isolda DCT ensures pitch-black backgrounds.
 
With genuinely silent backgrounds,” letting subtle details shine.
 
 

Perfect Impedance Matching

With an 8-ohm impedance matching typical speakers, the Isolda DCT prevents distortion from mismatched cables. townshendcable.com explains this preserves square waves, ensuring “no ringing or distortion.”
 
 

Unequal Lengths, Same Sound

Unlike other cables, Isolda DCT Speaker Cables perform flawlessly even in unequal lengths. Thanks to their advanced impedance-matching technology, the sound from each speaker remains identical, regardless of cable length. This flexibility makes them ideal for any audio setup, from compact home systems to sprawling high-end rigs.

Explosive, Precise Dynamics

 

EDCT-treated conductors deliver lightning-fast transients and vast dynamics for thrilling playback. Every note snaps with energy from whispers to orchestral peaks, as HiFi Pig praises its “bass clarity and space,” emphasising high-current handling, ideal for dynamic genres like rock or classical. The Isolda DCT brings music to life with unmatched precision and power.
 

Natural, Fatigue-Free Sound

We’ve engineered the Isolda DCT for a relaxed, natural sound, free from harshness or edge. Impedance matching and RFI immunity ensure effortless music flow, perfect for vocals or acoustics, and one astute audiophile’s tale of his relief from “Alice-in-Wonderland” cable woes. Enjoy hours of fatigue-free listening with emotional depth and clarity.
