Seismic Pods


Townshend has optimised a solution that employs a low pass mechanical filter, comprising mass, compliance and proportional damping, which isolates from 3.5Hz and up in all three planes, up/down, left/right and back/forth. A movement-sensitive, air-resistance damper rapidly dissipates low frequency oscillation caused by disturbing the suspended equipment. Townshend incorporates the Seismic Load Cell as the core element within the Seismic Vibration Isolation range designed to optimise all Hi-Fi components

SKU: N/A Category:


  • Eliminates structure-borne feedback between speaker and vibration sensitive equipment.
  • Enhances clarity throughout the whole frequency range.
  • Improves bass definition. Produces a wider and deeper sound stage.
  • Neighbour friendly high level listening.

Positioned under any piece of equipment, Seismic Isolation Pods will dramatically improve the sound by breaking the acoustic connection between the audio system and structural vibrations in the room.

The Seismic Isolation Pod is a Seismic Load Cell™ with a circular foot attached to the lower end cap for stability. The length may be adjusted by turning the top end cap, which allows easy levelling of audio equipment placed on a set of four Pods. There is a soft felt protective piece on the top and bottom faces of the end caps to allow for easy positioning and to prevent scratching.

A singular Seismic Pod is available with seven different weight range capacities, varying progressively from less than 1 kg up to 50kg. Virtually any weight of equipment can be isolated.

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.The maximum load when using four type “F” Pods is 200kg (440lb). For loads greater than this, simply add more Seismic Pods.

Each Seismic Pod 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 degree of out of balance is too large, then it is suggested to use additional Seismic Pods as necessary, 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” Pods, the maximum supported weight should be equal or less than 52.4 Kg
