Sizing up

The weight of your speakers is crucial in determining the right load cells for perfect isolation within the audio waveband. Our carefully calibrated Loadcells ensure the ideal spring-mass load, allowing your speakers to “float” and achieve comprehensive isolation from external vibrations. Once this balance is achieved, you’ll select a platform that fits your speakers as shown in the diagram. If there is a slight overhang at the front or back, this may be acceptable. For speakers that don’t fit any standard platforms, we offer a bespoke service to create a custom stand that perfectly suits your setup.

The Seismic Podiums become so fundamental to the listening experience that calling them mere accessories fails to give them enough credit.

Gader awarded the Podium Accessory of the Year 2020

 

Neil Gader, The Absolute Sound

The sensation of having a precision device is immediately clear… conferring a detailed and precise soundstage, with the same listening pleasure that restores the music from live performances.

AudioSinapsi

The way it removes the speaker’s interaction with its surroundings is mind-blowing, bringing clarity to the entire frequency range… It’s difficult to overstate the effect that these podiums can have.

Lee Dunkley, HiFi Choice

I couldn’t quite believe the improvement in coherence and timing it wrought, and the extent to which the sound is able to escape the boxes. Then there’s the bass, which is suddenly incredibly articulate, three-dimensional and powerful

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.

By isolating speakers from floor resonance (e.g., 50Hz on wood, 100Hz on concrete), the Podium delivers:
  • Transparency: Reveals hidden details with a “detailed and precise soundstage.”web:6
  • Dynamics: Tightens bass for “articulate, three-dimensional power.”web:0
  • Bandwidth: Creates a “holographic soundstage” across genres.web:5
    Users report, “The effect on clarity, soundstage, and bass cleanup has to be heard to be believed.
The Podium supports standmount, floorstanding, and subwoofer speakers from 13.2kg to 200kg (custom options up to 240kg), with five platform sizes for bases from 30cm x 40cm to larger custom dimensions. It’s ideal for speakers like Focal Sopra 2, Martin Logan Summit X, or Dynaudio Consequence.
Both use identical Seismic Load Cells™ for equivalent sonic benefits, but the Podium’s broader platform offers greater stability for heavier speakers (>30kg) or complex setups. “The Podiums are fundamental to the listening experience,” unlike the Bars’ compact design for smaller speakers.
Remove speaker spikes, place the Podium on the floor, and position the speaker on top, using the fine-leveling adjustment screws to ensure stability. Setup takes minutes, and the 20mm height increase optimizes bass without repositioning. Detailed instructions are provided.

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.

Yes, it works on wood, tile, concrete, or carpeted floors, with adjustable Load Cells compensating for uneven surfaces. Users confirm effectiveness across setups, including suspended wood floors, reducing neighbor disturbances.
Unlike spikes that transmit vibrations, the Podium’s 3Hz isolation outperforms partial solutions like Sorbothane or IsoAcoustics Gaia. An Audiogon user noted, “There is definitely more clearly defined bass notes” compared to Gaia 1, with superior midrange detail.

Crafted from high-grade steel with robust Load Cells, the Podium is built for longevity, backed by a 5-year warranty. Its UK-made construction withstands environmental variations, ensuring consistent performance. Designed for a lifetime of enjoyment
Low-frequency vibrations (3–10Hz) from footsteps, traffic, or HVAC systems resonate through floors, muddying bass and blurring mids. The Podium’s 3Hz cutoff eliminates these, ensuring “incredibly articulate, three-dimensional bass” (Hi-Fi+) and a cleaner soundstage, especially in urban environments or on suspended floors.
By isolating speakers above 3Hz, the Podium prevents low-frequency vibrations (e.g., bass rumble at 20–100Hz) from transferring through floors to neighbours, unlike spikes that amplify structure-borne noise. Users on What Hi-Fi? Forum confirms, “No vibration through the floor,” enabling louder playback without complaints, ideal for apartments or shared spaces.
Yes, for unusual or very heavy speakers (e.g., >200kg or non-standard footprints), we can create bespoke Podiums tailored to your speaker’s exact footprint and weight. Contact Townshend with your speaker’s dimensions and specifications for a custom platform, ensuring optimal stability and 3Hz isolation, as used for 250+ lb Dynaudio Consequence speakers.
For unusual or very heavy speakers, we need to make a drawing and get the plate cut to size, which can add a few weeks to the lead time. Custom Podiums are a little more expensive due to the added time to make, but they are worth the investment, and we strive to keep the price down—contact us at mail@townshendaudio.com (mailto:mail@townshendaudio.com) for a quote.
Precise levelling is needed to avoid wobble, especially for heavy speakers (>100kg), which may require custom Load Cells. Select the correct size and weight capacity using Townshend’s chart. Prices start at £1,750 per pair.web:
Unlike attenuators like IsoAcoustics Gaia (6–8Hz isolation), Stillpoints (~5Hz), or Sorbothane (10–15Hz), which partially dampen vibrations, the Podium’s 3Hz decoupling fully isolates speakers from low-frequency floor resonance (e.g., 3–10Hz from footsteps, traffic), preventing bass smearing and midrange blur. An Audiogon user switching from Gaia noted, “There is more clearly defined bass notes” and “more hidden clues in the music,” revealing a transformative clarity, dynamics, and soundstage depth unattainable with mere attenuation.
