Seismic Corners

Seismic Corners by Townshend Audio: Instant Isolation for Your Hi-Fi Rack

Elevate your audio experience with Townshend Audio’s Seismic Corners, the ultimate solution for instantaneously isolating your entire hi-fi rack and all its components in one elegant step. Designed to slip effortlessly under the four corners of your audio rack, these innovative devices decouple your system from destructive groundborne vibrations, delivering unparalleled sound clarity across every piece of equipment.
 

Sizing up

The weight of your speakers is crucial in determining the right load cells for perfect isolation within the audio waveband. Our carefully calibrated Loadcells ensure the ideal spring-mass load, allowing your speakers to “float” and achieve comprehensive isolation from external vibrations. Once this balance is achieved, you’ll select a platform that fits your speakers as shown in the diagram. If there is a slight overhang at the front or back, this may be acceptable. For speakers that don’t fit any standard platforms, we offer a bespoke service to create a custom stand that perfectly suits your setup.

Calculating the Right Load Cell
To ensure optimal performance, calculate the total weight of your hi-fi rack including all equipment (amplifiers, turntables, DACs, etc.) and the rack itself. Divide this total by four to determine the load per Seismic Corner, then select the appropriate Seismic Load Cell™ rating from our range (e.g., 5-20kg, 20-50kg per corner). For example, a 100kg rack with gear requires four corners rated for at least 25kg each. Refer to our Load Capacity Guide for precise sizing.

Two Types for Perfect Compatibility

Seismic Corners come in two variants to suit different rack designs:
  • S-Type (Spiked or Column Racks): Tailored for racks with spiked feet or narrow columnar legs, the S-Type features a precision-engineered cup to securely cradle spikes or pointed supports, ensuring stable isolation.
  • F-Type (Flat-Bottomed Racks): Designed for solid, flat-bottomed racks, the F-Type provides a broad, stable platform to evenly distribute weight and maximize isolation.
 
Refer to our Load Capacity Guide for precise sizing.

I’ve used Townshend Seismic products under my rack and turntable, and the difference is night and day. Bass is cleaner, and there’s a sense of calm in the soundstage.” While not explicitly about Corners, this user experience aligns with the expected benefits of rack-wide isolation, particularly for sensitive components like turntables.

The Seismic Corners under my audio stand stopped all vibrations from nearby traffic. My turntable no longer picks up floor noise, and the overall sound is crisper, especially in the highs.” – User, Townshend Seismic Isolation forum

My entire system has benefited from the corners. I have moved the platform over to my DAC. I am so astounded by the platform’s benefits and corners that I have ordered the podiums to go under my speakers. I’m bought into the benefits of the Townshend isolation products.

Perfect for standmount, floorstanding, or subwoofer setups, this award-winning platform is a game-changer for audiophiles. Discover ten compelling reasons to make the Seismic Podium the cornerstone of your audio system

Revolutionary Vibration Isolation

Our Seismic Podium isolates speakers from groundborne vibrations above 3Hz, using damped spring Load Cells™ to block microtremors from traffic, footsteps, or seismic activity. This decoupling prevents speaker cabinet resonance, delivering pure, undistorted sound. The Absolute Sound (2020 Product of the Year) calls it “fundamental to the high-end experience,” making it essential for pristine audio.

 

Dramatic Bass Control

Say goodbye to bass boom. The Podium’s isolation reduces floor resonance, producing tight, articulate low frequencies. HiFi+ praises its ability to “clean up the bass like you wouldn’t believe,” ensuring every note is precise, not bloated. Perfect for bass-heavy genres like EDM or classical.
 
 

Expansive 3D Soundstage

Our Podium creates a holographic soundstage, freeing speakers from room constraints. Instruments are pinpointed with lifelike precision, as Tracking Angle describes: “Widened soundstage with better pin-point imaging.” Your listening room transforms into a concert hall, immersing you in music.
