About the Seismic Podiums
The Townshend Audio Seismic Isolation Podiums are engineered to accommodate any size and weight of speaker, including standmounts, floorstanders, and subwoofers. They break the acoustic connection between the floor and speaker, preventing the passage of deleterious vibrations both to and from the speaker cabinets, which significantly improves sound quality by reducing bass boom, enhancing clarity, and expanding the soundstage. Each podium uses Townshend's innovative 'Captive' Load Cell technology, consisting of a high-quality alloy steel compression spring surrounded by a flexible synthetic rubber jacket with two end plates and a movement-sensitive air-resistance damper. This design allows free movement in all three dimensions and blocks vibrations from 3Hz upwards. The podiums have a stable four-square footprint extending beyond the speaker perimeter, with fine leveling adjustment via a rotatable top cap and an adjustable foot to compensate for uneven floors. The platforms are made of tough black steel with a large treadplate area suitable for any medium to large speaker or subwoofer, with or without spikes. They are suitable for wood, tile, or carpeted floors and increase speaker height by only 20mm (3/4 inch). Available in five standard sizes and custom sizes for very heavy speakers, the podiums provide a significant upgrade in musical performance, delivering clearer, more natural sound with a larger, deeper, and wider soundstage. They are highly regarded in the audiophile community for their fundamental contribution to high-end audio performance.
