Seismic Isolation for Piano Forte

A major advance in piano technology

A surprisingly high percentage of the sound that comes out of a piano travels through the legs and into the floor. This can both ‘muddy’ the sound and become an annoyance to neighbours. 

Break this link with the seismic piano isolators and the result is simply magical!

The piano is now more responsive to the pianist’s touch and the sound is remarkably more lively, pleasant and tuneful. The improvement in sound is very noticeable and immediately appreciated by all who experience it.

Using the isolators, the piano is now decoupled from the floor, virtually eliminating the vibrations generated by playing the piano from entering the building. This makes it very neighbour friendly.

Townshend Audio, who are specialists in acoustic vibration control in the audio industry, introduces the Piano Isolators. The devices are placed under the piano legs to break the acoustic connection to the floor.

A central recess will accommodate and centre all sizes of castor. The isolators will accommodate pianos weighing up to 500kg and will raise it by about 25mm (1”), which is virtually unnoticeable when played. To install the isolators a purpose built hydraulic jack is available to lift the piano.

Stephan Hough's Experience

“These piano isolators are wonderful. Perhaps their original purpose was to prevent neighbours from being disturbed by the thunder of mighty chords through floorboards. But there’s a counter-melody here. 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.”

frequently asked questions

Townshend Piano Isolators are specialized devices designed to reduce vibrations and improve sound quality for grand pianos. They isolate the piano from its environment, minimizing the transfer of vibrations to and from the floor.

By isolating the piano from floor vibrations, they eliminate muddiness and enhance clarity, responsiveness, and tonal purity. Pianists often notice livelier, more vibrant notes with improved attack and decay, making the instrument sound freer and more transparent.
A significant portion of a piano’s sound travels through its legs into the floor, muddying the tone and potentially disturbing neighbors. The isolators break this acoustic link, keeping the sound pure and reducing structural noise transmission.
They’re designed for grand pianos with three legs and can support weights up to 500kg (1100 lbs). A central recess accommodates various caster sizes, making them versatile for brands like Steinway, Bösendorfer, Fazioli, and Kawai.
A purpose-built hydraulic jack (available from Townshend) lifts the piano slightly—about 25mm (1 inch)—allowing the isolators to be placed under each leg. The process requires care, often two people, but no permanent modifications to the piano are needed.
They raise the piano by approximately 25mm (1 inch), which is subtle and typically unnoticeable when playing. Pianists report the instrument feels more responsive and “agile” due to reduced vibration interference.
 
Yes, by decoupling the piano from the floor, they significantly reduce vibrations transmitted through the building, making it a neighbor-friendly solution, especially in apartments or shared spaces.
Each set supports up to 500kg, suitable for most grand pianos. The Load Cells are adjustable to ensure level placement and optimal isolation, even on uneven floors.
Pianists like Stephen Hough and Mark Swartzentruber praise their transformative effect—cleaner bass, clearer polyphony, and a more enjoyable playing experience. At around £1,208 (as listed on townshendisolation.com), they’re a premium upgrade for serious musicians or those in noise-sensitive environments.
Unlike rubber pads or rigid stands, which only dampen higher frequencies (e.g., 14Hz+), Seismic Piano Isolators block vibrations from 3Hz across all planes, offering superior isolation and a more natural sound compared to the “analytical” tone of rigid couplers.
No, once installed, they’re maintenance-free. The Load Cells are robust and designed for long-term use without adjustment or replacement.
Yes, they work on any floor type—wood, tile, carpet, or concrete. The adjustable feet ensure stability, though very uneven surfaces might need minor shimming for perfect leveling.
Classical pianist Stephen Hough notes, “Somehow these isolators sweeten and clarify the sound… pure notes singing freely in the air.” Mark Swartzentruber adds, “They improve responsiveness to touch… as if the room’s acoustics or the piano itself were upgraded.”

Installation is generally straightforward. Most products are designed to be placed directly under your equipment, and no special tools or modifications are needed. For instance, Seismic Pods or Platforms can simply be positioned beneath your components, while Podiums and Bars are placed under speakers or racks.

They’re available directly from townshendaudio.com or townshendisolation.com, or through authorized dealers like Future Shop or Analogue Seduction. Contact Townshend for custom inquiries or shipping details and guidance on installation.
The cost is notable, and installation requires careful lifting of a heavy instrument. Some might find the subtle height increase affects bench positioning slightly, though this is rare.
and the piano feels more alive—reacting to touch with heightened sensitivity. This takes getting used to but mimics the natural movement of instruments on the best concert hall stages, a quality most homes lack, allowing your piano to produce a professional-grade sound.
