The Townshend Seismic Isolation was the easiest part of the installation. The settings were spot-on, fitting the Tannoy Westminsters like a glove, and the sound was incredible!

The Custom Podiums arrived at the installation perfectly calibrated for the Megolith speakers. It was the easiest part of a challenging day.

Seismic Platform: How it works

The Townshend Seismic Isolation Platform uses patented Seismic Load Cell™ technology to shield your hi-fi equipment from vibrations that degrade audio quality. Sensitive components like turntables, DACs, and amplifiers are vulnerable to disturbances from footsteps, speaker feedback, or even global microtremors. By acting as a low-pass mechanical filter, the platform isolates vibrations as low as 3Hz across all planes. This ensures your music remains free from jitter, noise, and distortion, delivering a soundstage with exceptional clarity and precision.

Enhanced Audio Fidelity for Every Component

Vibrations compromise the performance of critical hi-fi components,

such as a record player’s stylus tracking microscopic grooves or a DAC’s crystal oscillator maintaining timing accuracy. The Townshend platform stabilizes these devices, preserving their intended performance. The result is razor-sharp transients, deeper bass, and a level of detail that reveals nuances in your music you may never have noticed. Whether you’re an audiophile or a casual listener, this platform transforms your system’s output into a more immersive experience.
