TOWNSHEND AUDIO ADJUSTABLE SEISMIC BARS SIZE 2 420mm - 724mm 16.5" - 28.5" Inches

  • Produce a wider and deeper sound stage.
  • Enhance clarity throughout the whole frequency range.
  • Improve bass definition.
  • Eliminate structure-borne feedback between the speaker and vibration sensitive equipment.
  • Allow for neighbour friendly high level listening.
  • Eliminate irritating boom caused by coupling through the floor to adjacent rooms.


The Seismic Bars add a mere 2cm to the height of a loudspeaker. This is important not just for obvious centre-of-gravity reasons, but because boundary proximity affects low frequency performance, so raising a speaker up too far will make for a leaner bass than originally intended.


Seismic speaker Isolation Bars are designed to break the acoustic connection between speakers and the floor, thus preventing the passage of unwanted vibration between the two. Used in pairs under any speaker, be it floor standing, or stand-mounted, including sub-woofers. They are used in pairs under any speaker whether it is floor standing, stand-mounted or a sub-woofer. Due to the exceptionally compliant nature of the Seismic Load Cells, the speakers effectively float in the room at frequencies above 3 Hz. Each bar comprises a strong steel cross-piece with raised ends under which two Seismic Load Cells are attached.

Each bar comprises a very strong steel cross-bar with raised ends under which are attached two Seismic Load Cells.
When installed you experience The Townshend effect, the sound improves dramatically, wider width and greater depth and becomes independent of the speakers. Bass becomes tighter and real, with thuddy boom eliminated. A major plus is that the sound of the speakers is no longer transmitted through the structure of the building so your neighbours can no longer hear your music.   
Conventional so-called rigid supports (spikes or cones) aim to hold the speaker cabinet "still" at audio frequencies. However there will be a resonance set up by the mass of the cabinet reacting with the unavoidable springiness of the floor, which can cause vibration of the building structure in the audio band. Rigid coupling also transmits ground-bourne vibration into the speaker cabinet and thence to the speaker driver baskets where it is superimposed onto the music. By using Seismic Isolation Bars you will be able to enjoy your music at its natural volume,- as if you were listening to a live performance-without annoying the neighbours 


"Townshend Seismic Speaker Bars produce a result that goes way beyond what you might expect from ‘speakers on springs’. To get an improvement in absolute resolution, precision of timing and solidity of stereo image from something so apparently simple is extraordinary. These things really do change the game, move the goalposts, and revolutionise the way we should think about speaker support. This is not an accessory… it’s an essential." Jason Kennedy HIFI+
