Townshend Audio Seismic Isolation Platform

Music is energy across the entire frequency spectrum — from the deepest foundations of bass to the finest shimmer of harmonics. 

Any vibration that reaches your equipment, no matter how small, interferes with that energy and diminishes the music.

Recent independent research into vibration isolation has confirmed what Townshend Audio has known for decades: a properly engineered damped spring offers the most effective and consistent protection across the critical low-frequency range. 

Townshend takes this principle further. Our patented Seismic Load Cell™ combines a precision spring with controlled air damping inside a flexible rubber jacket. This unique design delivers outstanding isolation at the lowest frequencies while completely eliminating residual ringing and unwanted energy in the mid and high ranges.

The result is a true mechanical low-pass filter that works in all planes, isolating your components from structural, airborne and self-generated vibration right down to 3 Hz. Your turntable, DAC, amplifier or streamer is left free to perform exactly as its designer intended — with wider soundstages, tighter bass, cleaner transients and a level of natural realism that transforms the listening experience.

The weight of your audio equipment is critical in choosing the correct Load Cells for flawless isolation across the audio waveband. Our precisely engineered Seismic Load Cells™ are calibrated to create the perfect spring-mass balance, enabling your record player, DAC, or components with piezoelectric connectors to “float” in a vibration-free state, shielded from external disturbances. Once this optimal balance is achieved, you’ll select a platform size that matches your equipment, as illustrated in our sizing guide. A slight overhang at the front or back is often acceptable.
