The Townshend Seismic platforms and Podiums employ a mass-spring system to provide the perfect solution. Here’s how: Designed to decouple audio components from external mechanical vibrations above 3Hz, a frequency chosen to be well below the audio band but high enough to filter out virtually all unwanted vibrations such as footsteps, doors closing, lifts operating and global seismic effects. These Seismic Isolation products use a damped mass-spring system which is easy to adjust to suit the weights of a wide range of audio components and a revelation in sound quality. We work closely with clients to find the right load mass solution for you and continue until all unwanted vibrational resonances are eliminated from the audio chain. Giving clearer and greater musicality to your cherished music library.

Master Class Dynamic Parallel AC Line Conditioner (MainStream)

Elevate your high-end audio or video system with MainStream, a cutting-edge parallel AC line conditioner designed to banish interference from your home’s power lines. Everyday appliances—refrigerators, air conditioners, washers, dryers—and even external sources flood your AC mains with disruptive RF noise and energy pulses. MainStream tackles this head-on, delivering cleaner power to your components without ever restricting current flow.

Unlike traditional “series” conditioners, MainStream works in parallel—simply plug it into the mains socket nearest your equipment. It filters out interference across multiple frequency bands using a streamlined topology with minimal, high-quality components. No current passes through it, so there’s no limit to how many you can use—perfect for large systems. Say goodbye to hum, hiss, buzzing, or vibrations in your speakers, turntables, or chassis, and banish fuzzy images or moving bars from video displays.

MainStream’s tuned reactive filters target noise known to degrade audio and video performance, reducing system background noise to near-silent levels. Encased in a sleek, milled aluminum housing with a subtle blue glow to signal operation, it’s built for a lifetime of reliable service. Laboratory-proven via Fast Fourier Transform graphs, MainStream offers premium performance at a reasonable price—no resonant transformers, just pure interference elimination.

Key Features:

Reduces AC mains noise across multiple frequency bands
Enhances audio clarity and video quality
Parallel design: no current restriction, scalable for any system

Townshend Audio Seismic Podium – The Ultimate Foundation for Sonic Excellence

Elevate your listening experience to new heights with the Townshend Audio Seismic Podium (starting at £1,750 per pair). Engineered in the UK, these award-winning isolation platforms break the acoustic connection between your speakers and the floor, unleashing a sound so clear, deep, and natural that it’s nothing short of revelatory. Designed for any speaker—stand-mounts with stands, floorstanders, or subwoofers—the Seismic Podium eliminates structure-borne feedback, banishes bass boom, and delivers a wider, deeper soundstage that transforms your music. Priced for the serious audiophile, this is the no-compromise solution for neighbor-friendly, high-level listening.

Sever the Ties, Free the Sound

Speakers don’t just play music—they interact with the floor, sending vibrations downward and receiving seismic interference in return. This coupling muddies bass, blurs clarity, and sends irritating boom into adjacent rooms. The Seismic Podium stops this dead in its tracks. Using four ‘Captive’ Seismic Load Cells™ in a stable, four-square configuration, it floats your speakers above the floor’s influence, isolating vibrations in all directions from 3Hz upward. The result? Enhanced clarity across the entire frequency range, improved bass definition that’s tight and controlled, and a soundstage so expansive it feels like the performers are in the room with you.

A Revolution in Audio Precision

Crafted from tough black steel, each Seismic Podium offers a large, adaptable platform that supports any medium-to-large speaker or subwoofer—spikes or no spikes. The Load Cells feature adjustable top caps for fine leveling and bottom feet to compensate for uneven floors, ensuring a rock-solid foundation on wood, tile, or carpet. Raising your speaker by just 20mm (¾”), the Podium maintains optimal bass balance while severing the resonance between the cabinet and the floor. Suddenly, the sound becomes more tuneful, natural, and enjoyable—free from the distortions that once held it back. Playback at realistic volumes becomes a guilt-free pleasure, as vibrations no longer rattle walls or annoy neighbors.

Tailored to Every Speaker

Available in five standard sizes (or custom-ordered for behemoths), the Seismic Podium comes in multiple load capacities to match your setup:

Type A: Up to 13.2kg (four Load Cells).
Type C: Up to 52.4kg—perfect for most floorstanders.
Type F: Up to 200kg for massive systems.

Check the load capacity graph to select the right rating, and contact us for guidance on uneven or heavy loads. For stability and ease, we recommend sticking to weights within the specified range per type—e.g., four “C” Load Cells handle up to 52.4kg safely. Whether it’s a sleek stand-mount or a towering subwoofer, the Podium’s extended footprint ensures unwavering support without tipping risks.

Award-Winning Performance

The Seismic Podium isn’t just a product—it’s a phenomenon, lauded by the audio world:

The Ear Editor’s Choice 2018
HiFi+ Accessory of the Year 2016
Stereo Times Most Wanted Component 2020
The Absolute Sound Product of the Year 2020
HiFi Choice 5 Stars & more.

Reviewers and owners alike call it “magical” and “a must-have,” praising its ability to reveal details in music they’d never heard before. It’s the ultimate speaker support for both professional installations and home hi-fi, delivering unprecedented performance with zero compromises.

Vibration Isolation: Blocks feedback from 3Hz up, eliminating floor coupling.
Design: Steel platform with four adjustable ‘Captive’ Load Cells™.
Load Capacity: Five types, from 13.2kg to 200kg (four Load Cells).
