Townshend Seismic Isolation Pods

  • 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.
Please note: There are 7 spring weight capacities. Please chose the type of spring from the table which is appropriate for the weight of your equipment and then select from the dropdown box before ordering. If you are unsure about the appropriate option for your equipment please contact us.
Please note: Price is for 1 individual pod. Add 4 to your basket for a complete set of 4 pods.
The singular Seismic Load Cell is available with seven different weight capacities, ranging progressively from 1kg up to 32kg. Virtually any weight of equipment can be isolated.


The spring rates are as follows: 


Spring Min weight Max weight Colour Code
AAA 0.5kg (1lb) 1kg (2lb) Brown
AA 1kg (2lb) 2kg (4lb) Red
A 2kg (4lb) 4kg (9lb) Orange
B 4kg (9lb) 8kg (17lB) Yellow
C 8kg (17lb) 16kg (35lb) Green
D 16kg (35lb) 32kg (70lb) Blue
E 32kg (70lb) 64kg (140lb) Silver

The maximum load when using four E springs is 256kg (560lb). For loads above this, eight or more load cells may be required. 

For out of balance loads where the centre of gravity of the component is not near the geometrical centre of the component, each support foot is screw adjustable in length to allow for this. If the degree of out of balance is too large, then it is suggested to use unequal springs. 

For example, a with valve amplifier with the transformers at the rear, then use two “B” springs at the front and two “C” springs at the rear. 

The simplest implementation is to utilise the Seismic Pods in sets of four. It is possible to utilise three pods, but this arrangement is difficult to level satisfactorily and the effect of the weight of the cabling may also complicate matters. 

It is advisable to dress the cables such that they do not act as a mechanical short circuit negating the effect of the Seismic Isolation. Common sense and a little experimentation is advised. Try to avoid very heavy and stiff cables. 

If it is difficult to position the individual Pods, it is advised to employ the Seismic Sink Platform. The advantage here is that the equipment may be re-positioned without upsetting the level. Also, for very heavy equipment, it is very difficult to position the Pods whilst holding up the equipment single handed.
