The Seismic Platform is a unique isolation concept that works by preventing vibration from corrupting delicate audio signals

 

The benefits of isolating gramophone turntables from mechanical vibration have been understood for some time.

But what about DACs and CDs?

CD mechanisms are almost as critical as turntables since they have to read 5-micron tracks accurately at speeds of over 5 miles per hour. Unfortunately, the crystals used in the clocks which control the timing circuitry of DACs and CD mechanisms are very sensitive to mechanical vibrations. So for optimum error-free performance, some isolation is necessary to protect these digital components from harmful vibrations.

The Townshend Seismic platform employs a mass-spring system to provide the perfect solution.

Why Choose Townshend Seismic Isolation?


An immediate sound upgrade for all Audio separates

Especially designed to isolate individual components such as CD players, turntables, DACs, preamplifiers, power amplifiers, computers and streamers from deleterious vibration.

The Seismic Isolation Platform includes a durable slim steel top plate that integrates unobtrusively under any hi-fi component.

The acoustically dead constrained-layer damped plate combined with a Seismic Load Cell™ attached to each corner is the ultimate combination to absorb and isolate unwanted vibration, including structural, air-borne and that generated by the hi-fi equipment.

Measuring up for your seismic Platform

The Seismic Isolation Platform is available in three standard sizes:

  • Size 1 43x30cm (17×12″)
  • Size 2 48x35cm (19×14″)
  • Size 3 52x40cm (20.5×16″)

 

Platform working height is approximately 40mm (1.5″)

The Platform can be levelled by turning the adjustable Seismic Load Cell™.

It is important to specify the weight of your equipment when ordering. Bespoke platforms are available for any size or weight of audio equipment.

Seismic Platforms are available with seven different weight range capacities, varying progressively from less than 1 kg up to 200kg.

The maximum load when using four ( 4) type “F” Load Cells is 200kg (440lb). For loads greater than this, simply add more Load Cells. Virtually any weight of equipment can be isolated.

Eliminate footfall issues

Our Seismic Isolation technology is engineered to eliminate vibrations as low as 3Hz. This is in stark contrast to rigid couplers, which are often tuned higher and can make music sound edgy and overly analytical. Our tuned suspensions ensure a smoother, more relaxing listening experience, free from the distortions introduced by higher-frequency vibrations.

levelling

Each Load Cell is screw adjustable in height to allow for out of balance loads where the centre of gravity of the component is not near its geometrical centre. If the level balance cannot be achieved, then it is suggested to use additional Seismic Pods positioned under the Platform as necessary, to balance the load.

For asymmetric components such as a valve (tube) amplifier with the transformers at the rear, different load capability Seismic Load Cells™ can be used to balance the load.

We suggest, for reasons of ease of set-up and loads that are not equally distributed, that consumers always select the stronger Load Cell where two values overlap in the graph below.

For example, when using four (4) type “C” Load Cells, the maximum supported weight should be equal to or less than 52.4 Kg.

Jason Kennedy reviews the Townshend Seismic Isolation Platform under the Rega RP6 Turntable, a Leema Antila CD Player & Naim UnitiLite Massive increase in stereo three dimensionality, sound is clearer” A degree of hardness has disappeared and left a stronger sense of timing. “Bass goes deeper” Voice has regained its full richness, Quite a transformation in truth, and one that you’d be hard pressed to replicate with any similarly priced upgrade. The Townshend Seismic Platform seems to be able to transform the potential of electronic components as well as, if not better than turntables. What is clear is that few hi fi components give their best without isolation and the platform delivers as much in a neat and effective package and comes highly recommended.”

Unlock the true potential of your audio system with the Townshend Audio Seismic Isolation Pods. Precision-engineered in the UK, these compact yet powerful devices break the acoustic connection between your equipment and structural vibrations, delivering a listening experience that’s clearer, deeper, and more immersive than ever before. Priced for the discerning audiophile, the Seismic Pods are the secret weapon to banish feedback, refine your sound, and keep the peace with your neighbors—all while fitting seamlessly under any piece of gear.
Cut the Feedback, Free the Music
Structure-borne vibrations are the silent enemy of great audio, traveling from speakers to sensitive equipment and muddying your sound with unwanted resonance. The Seismic Isolation Pods put an end to this interference. Positioned under any component—amplifiers, turntables, CD players, or speakers—these pods use a single Seismic Load Cell™ to float your gear above 3Hz, eliminating feedback across the entire frequency spectrum. The result? Enhanced clarity that reveals every detail, improved bass definition that hits with precision, and a wider, deeper soundstage that pulls you into the heart of the music.
Sonic Precision Meets Practical Design
Each Seismic Pod is a marvel of simplicity and performance. A robust Seismic Load Cell™ is paired with a circular foot for stability, while a screw-adjustable top end cap lets you fine-tune height and level uneven loads with ease. Soft felt pads on both ends protect your equipment from scratches and ensure smooth positioning. Whether your valve amp has heavy transformers at the rear or your turntable needs perfect balance, the pods adapt effortlessly—use different load capacities to match asymmetric weight distribution, or add extra pods for heavier setups. With a maximum capacity of 200kg (440lb) using four “F” Pods, and the option to scale up for even greater loads, no system is too big or too small.
Tailored to Every System
The Seismic Isolation Pods come in seven weight-range capacities, from under 1kg to 50kg per pod, ensuring a perfect fit for any piece of equipment:
  • <1kg: Ultra-light components like DACs or streamers.
  • Up to 13.2kg: Medium-weight gear (four “B” Pods).
  • Up to 52.4kg: Heavier systems like amps (four “C” Pods).
  • Up to 200kg: Full setups with four “F” Pods—or more for larger loads.
For uneven loads where the center of gravity isn’t centered, simply adjust the height of each pod or mix and match capacities. When weights overlap in the capacity chart, opt for the stronger Load Cell for easier setup and stability—e.g., four “C” Pods handle up to 52.4kg safely. This flexibility makes the Seismic Pods a universal solution, whether you’re isolating a featherweight phono stage or a hulking power amp.
Hear the Difference, Feel the Peace
The benefits are immediate and profound: bass tightens into punchy, articulate notes; mids open up with breathtaking transparency; and highs sparkle with newfound detail. Your soundstage expands in width and depth, creating a 3D listening experience that’s as close to live as it gets. Better yet, high-level listening becomes neighbor-friendly—vibrations that once rattled floors and walls are stopped in their tracks, letting you crank the volume without the guilt. Audiophiles call it “a revelation” and “the best tweak for the money”—a small investment with a massive payoff.
