SEISMIC BARS
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.

By using Seismic Isolation Bars, you will be able to enjoy your music at its natural volume level, – as if you were listening to a live performance – without annoying the neighbours!

To install, first, remove any spikes or cones from your speakers and slip one bar under the front of the speaker. Then tilt the speaker forward and slide the second bar under the rear. Very small adjustments allow for setting the speakers vertical. Even though the speakers are floating, it takes a very big push to topple them.

The Seismic Bars are available with five different weight range capacities, varying progressively from less than 5kg up to potentially over 75kg.

We strongly recommend using Seismic Podiums for loads above 30kg if single-handed, or up to 75kg for ease of use and stability reasons, especially on equipment taller than 1m and/or high center of gravity.

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” Load Cells, the maximum supported weight should be equal to or less than 52.4 Kg, including the weight of the Podium base plate vibration into the speaker cabinet and thence to the speaker driver baskets where it is.

eismic Isolation Bars for Speakers and Sub-woofers

Seismic Isolation Bars are designed to break the acoustic connection between the speakers and the floor, thus preventing the passage of unwanted vibration between the two. Used in pairs under any speaker, be it floor standing, stand-mounted or sub-woofers.

Because of the very compliant nature of the Seismic Load Cells™, the speakers effectively float in the room at frequencies above 3Hz. Each bar comprises a very strong steel cross-piece with raised ends under which are attached two Seismic Load Cells™.

When installed you experience The Seismic Effect! The sound improves dramatically, with wider stage width and greater depth and the sound becomes independent of the speakers. Bass becomes tighter and more real, with thuddy boom greatly reduced. A major plus is that the sound of the speakers is no longer transmitted through the structure of the building with the same intensity, so your neighbours will probably not 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 coupling between the speaker and the floor and myriad 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-borne vibration into the speaker cabinet and thence to the speaker driver baskets where it is superimposed onto your music.

Neil Gader The Absolute Sound

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

Lee Dunkley Hi-Fi Choice

“The way it removes the speaker’s interaction with its surroundings is mind blowing, bringing clarity to the entire frequency range that enables it to communicate more effectively with the listener. You haven’t truly heard how your speaker can perform until you’ve placed it on one of these. Enthusiastically recommended.”

Jason Kennedy

“So what do Seismic Podiums do for sound quality? If I said “everything” you wouldn’t believe me, but the answer is not far off. They dramatically increase low level resolution so you can hear more detail, they clean up the bass like you wouldn’t believe and the improve dynamics and speed.”

Why Choose Isolda Speaker Cables?


Most speaker cables in the audio industry overlook the science of transmission line theory, resulting in micro-reflections that smear and veil the purity of sound. These reflections bounce between the source and speaker, muddying the music you love. The Isolda DCT Speaker Cable eliminates this issue through its unique geometry, closely matching the impedance of your amplifier and speakers. The result? A crystal-clear soundstage, lifelike 3d imaging, and seismic bass that transforms your listening experience.
