Coherence, timing, and drive are as good as any I’ve encountered
- Eliminates structure-borne feedback between speaker and vibration sensitive equipment.
- Enhances clarity throughout the whole frequency range.
- Improves bass definition.
- Produces a wider and deeper sound stage.
- Neighbour friendly high level listening.
Seismic Corners provide vibration isolation for almost any equipment rack, stand and platforms. Each Seismic Corner is a small platform suspended from two Seismic Load Cells™ on which the equipment legs or spikes are placed.
Designed to float your existing equipment rack in an unobtrusive manner, the Seismic Isolation Corners slip discretely under the bottom corners of your support furniture and bring you all the benefits of Seismic Isolation without major upheaval.
There are two types of Corners; one for flat feet (F) and one for spikes (S).
The level may be adjusted easily when fully loaded.
Four Corners units are able to hold equipment weighing up to 400kg.
The Seismic Corners are available with five different weight range capacities, varying progressively from less than 20kg up to 400kg. Virtually any weight of equipment can be isolated.
We suggest, for reasons of ease of set-up and loads that are not equally distributed, that consumers always select the stronger Load Cell where two values overlap in the graph below.
For example, when using a set of four (4) Seismic Corners with eight (8) type “D” Load Cells, the maximum supported weight should be equal to or less than 170.4 Kg.
Solutions for equipment with either more or less than four supports/legs are available.



The Definitive Guide to Vibration Control in Audio Excellence
There are few audio products that are truly revolutionary, that can legitimately claim to have redefined the state of the art.
For audiophiles chasing the ultimate listening experience, this trio from Townshend, EAT, and STAX is a worthy investment
What makes the Allegri Reference truly exceptional is its ability to disappear from the listening experience
Colloms describes the Allegri Reference as a “virtually indistinguishable” link between input and output, offering a level of transparency that makes it a “clear window into the sound stage.
A real improvement of focus @ the top end. Even the bass is tighter. Huge change in the soundstage, The system has almost gone from stereo to surround sound. The Dusty in Memphis album, female vocals, full orchestra, especially show how the individual instruments are separated. It's quite possible to identify which bit of the cymbal the drummer is hitting. Pet Sounds of course uses every instrument in the book. Bass harmonicas, tambourines, and the vocals are just so separated & tight. Porcupine Tree, beautifully produced & pressed vinyl. Every instrument inhabits a different piece of the soundscape. Strip the Soul is just exquisite. I'm sure as they bed in, the Townshend's will get better still, but... so far it's love at first sight. Always loved the 989's but these supertweeters have taken them to a whole new level.
We sat down and i played one of my all time favorites Neil Young Comes a Time i now this album very well but not heard it like this before, the attack of the guitars, the extra resolution and bite of the guitars was nothing short of amazing, there was more snap to the drum beat, the top end is so much more realistic and enjoyable, while the mid range has gained resolution and body, the vocals are very natural sounding but also revealing, the bass seems to have improved, there is definitely more of it its early days but I'm keeping them and i am very happy with level 3, my speakers are Soundlabs Dynastats,
Lossless on the MacBook, DAB, Cd and analogue, vinyl and tape cassette all benefit from a fuller more emotional sound. Science is great, and will one day crack cancer and HIV but it struggles to quantify certain things in life and one of those things is emotion. I'm sure my hearing doesn't extend much above 16kHz or so and yet the super tweeters work and work well for me. I think transients, atmosphere, detail, attack and sustain all benefit as does timbre between instruments, sounds and especially vocals within the hearing range due to less distortion, less smearing and better definition at frequency extremes. Definitely not snake oil in my opinion.. ..A worthwhile investment and I will not be returning them or selling them on. Many Thanks Toni and keep the music musical..
