Seismic Isolation for Piano Forte

Watch Stephen Hough Video

Unleash the Soul of Your Piano

Imagine a grand piano that sings with newfound clarity, its notes vibrant, responsive, and free from the constraints of the floor beneath it. Townshend Audio’s Seismic Isolation for Piano Forte redefines piano performance by breaking the acoustic connection between your instrument and the ground. A surprising amount of a piano’s sound—rich, resonant, and dynamic—is lost through its legs, absorbed by the floor, and muddied by structural vibrations. Our cutting-edge isolation technology sets your piano free, unlocking its full tonal potential while silencing disruptive vibrations that travel to adjacent rooms or buildings.

Key Benefits You’ll Love

Unrivaled Clarity:

Users consistently praise the isolators for cleaner bass, clearer treble, and a more responsive playing feel, particularly for soft dynamics and timing nuances.

neighbor-friendly

The neighbor-friendly aspect is noted, as the isolators reduce floor-transmitted vibrations, making them ideal for apartments or shared spaces

Floating Piano

The slight “wobble” (due to the piano floating on Load Cells) was mentioned by one user but deemed unnoticeable during play after adjustment

Why Your Grand Piano Needs Seismic Isolation

Sizing up

 
Grand pianos, whether a petite 400-pound Yamaha or a concert-ready 1,100-pound Steinway, transmit a surprising amount of sound through their legs into the floor. This not only muddies the tone but can also disturb neighbors. Townshend Seismic Piano Forte Isolators use advanced Seismic Load Cell™ technology to decouple your piano from the floor, virtually eliminating vibrations that interfere with sound quality and travel through the building structure. The result? A more responsive piano, crystal-clear notes, and a neighbor-friendly performance that lets you play with confidence.
Tailored to Your Piano’s Weight and Make
Every grand piano is unique, with weights varying significantly by make and model:
  • Petite Grand (e.g., Yamaha GB1K, 4’5”–4’10”): 400–500 lbs
  • Baby Grand (e.g., Kawai GX-2, 5’11”): 540–700 lbs
  • Medium/Parlor Grand (e.g., Steinway Model M, 5’7”): 500–700 lbs
  • Ballroom/Semi-Concert Grand (e.g., Bösendorfer 214, 6’2”–7’): 900–1,000 lbs
  • Concert Grand (e.g., Steinway Model D, 8’11”): Up to 1,100 lbs
To ensure your piano floats compliantly and is fully isolated, we customize the Seismic Load Cell™ capacity based on your piano’s specific weight and make. Each isolator, comprising a suspended triangular platform supported by three adjustable Load Cells, is placed under the piano’s legs and can support up to 500 kg (1,100 lbs) total. For heavier pianos or unique setups, we offer bespoke solutions with higher-capacity Load Cells.

“Somehow these isolators sweeten and clarify the sound of the instrument itself. Instead of a muddy confusion of carpet, wood and plaster I hear pure notes singing freely in the air. It’s a joy to have them under the castors of my pianos. Thrilled with these!”
Spephen Hough
Spephen Hough a renowned pianist and MacArthur “Genius” award winner
The Townshend under-piano floating isolators have been a remarkable upgrade to my 1909 Bösendorfer piano. The slightly muddy sound of this vintage piano has been transformed, the bass is much cleaner and articulate, and the whole piano benefits from a huge leap in clarity, without sacrificing the quintessential charm of the instrument. A several thousand pound upgrade in an instant!”

I have used the Townshend Piano Isolators on Steinway, Fazioli, Bösendorfer and Kawai pianos, and am impressed by the significant effect they have on sound quality and projection.”
Mark Swartzentruber
Mark SwartzentruberThe Cross-Eyed Pianist
In the beginning I was afraid that my piano would ‘wobble’ a little too much because of the isolating system. My grand piano weighs 295 kg, so we changed the tension a bit. It still wobbles a bit, but I don’t notice it when playing. The sound is more relaxed, more sonorous, not louder. It sounds natural, with warm, fabulous basses, and a less ‘tingling’ sound in the higher part of the piano… It’s especially easier to play soft, to separate lines. I feel more free in small timing details. My piano feels more ‘agile’: it reacts quick and feels more sensitive.”

The Science of Sonic Freedom

At the heart of our Piano Isolators lies Townshend’s proprietary Seismic Load Cell™ technology, a revolution in vibration control honed over decades in high-fidelity audio engineering. Each isolator is a precision-engineered platform suspended by adjustable Load Cells, comprising a high-tensile steel spring encased in a flexible synthetic rubber jacket with air-resistant damping. This creates a low-pass mechanical filter that isolates vibrations from 3 Hz upward, effectively floating your piano in a vibration-free zone.
Why It Matters: A piano’s sound travels not only through the air but also through its legs into the floor, where it becomes muffled or distorted. This structural coupling dulls the instrument’s responsiveness and muddies its tone. Our isolators sever this link, ensuring every note resonates with pristine clarity.

A Neighbor-Friendly Revolution

By decoupling the piano from the floor, our isolators virtually eliminate vibrations that transmit to adjacent rooms or buildings, making high-level practice sessions peaceful for those nearby.

Beyond elevating your piano’s performance, Townshend’s Seismic Isolation for Piano Forte is a game-changer for shared spaces. Vibrations from a piano can travel through floors and walls, causing annoyance in adjacent rooms or neighboring buildings—especially in apartments, studios, or historic venues. Our isolators stop these vibrations at the source, ensuring your music stays where it belongs: in your space.
Eliminate Structural Noise: By isolating vibrations above 3 Hz, our technology prevents the “irritating boom” that couples through floors to nearby rooms 

Practice Without Disturbance: Enjoy high-level playing at any time without worrying about complaints, making it ideal for urban settings or multi-unit buildings.
