Transform Your Sound Quality with Complete Vibration Isolation
At Townshend, we believe in the power of optimized vibration isolation to elevate your audio experience. Our philosophy is simple: fully float your entire Hi-Fi system independently from the speakers and the floor to unlock its true potential. With our complete solution, you can achieve this in the most optimal way by swiftly dissipating low-frequency oscillation caused by external disturbances allowing free movement in all three dimensions: up/down, left/right, and back/forth. This unique design effectively blocks all detrimental vibrations from 3Hz upwards and from any direction. As the frequency increases, the isolation capabilities further improve, ensuring that virtually no vibration can pass to or from the suspended equipment.
With each hi-fi component isolated using our technology, you will experience a progressive improvement in sound quality. Say goodbye to unwanted vibrations and welcome a pristine audio performance like never before.
By floating your hi-fi system with our vibration isolation solutions, you can unleash its full potential and immerse yourself in the captivating world of music. Join countless enthusiasts who have already experienced the transformative power of Townshend Vibration Isolation.
Elevate your sound quality today and explore our range of products designed to deliver an unparalleled audio experience.
Unlike other isolation methods that may address only limited resonances within the audio band, our Seismic Vibration Isolation range is meticulously designed to optimize all hi-fi components. Polymer materials, inertia blocks of granite, bungee cords, and other exotic substances may offer limited results, but they often fall short of achieving complete resonance interruption within the audio band. We believe in the Theory of More Stuff, pioneered by Proff. Jack Dinsdale, which highlights the limitations of such technologies.
Our Seismic platforms and podiums, however, employ a highly effective mass-spring system to provide the perfect solution. Designed to decouple audio components from external mechanical vibrations above 3Hz, our Seismic Isolation products filter out virtually all unwanted vibrations, including footsteps, doors closing, operating lifts, and global seismic effects. By utilizing a damped mass-spring system, our products allow for easy adjustment to accommodate a wide range of audio components, resulting in a revelation in sound quality.
We understand the importance of personalized solutions, which is why we work closely with our clients to determine the ideal load mass solution for their specific needs. Our dedicated team continues to refine the setup until all unwanted vibrational resonances are eliminated from the audio chain, resulting in clearer and greater musicality for your cherished music library.

Thank You for debunking the spike myth. For those of us on a budget, and space constraints, an appropriately cut piece of acoustic nub foam will have to take the place of the platform solution for smaller speakers. I tried it, and while not a perfect solution, it helps a lot. I did the test with a seismograph app, it's makes a big difference. Probably wouldn't work with bigger speakers for stability reasons though.

@geokrilov 5 лет назад

Never put your speakers on a foam nub. Spikes are not a myth. You don't need science (though there is science in it, but the opposite to mr. Townshend's one) - just listen to your speakers.

@jimboblivesforever 2 года назад

@@chrisrichards2827 My measurements with a seismograph app tell another story. They certainly don't kill all the vibrations, but for me, the foam pads reduce them significantly. Again, this is with small Tannoy bookshelf speakers, and I don't know how effective (or even safe) this is with bigger ones. But for my use case,the nub foam in the size of the speaker base solved the problem well enough, my neighbours are happier for it and the sound has actually tightened up a bit since the bass resonating through the stands and into the floorboards has decreased. I'd love to give those platforms in the video a go, but one of them costs more than my pair of Tannoys. As far as spikes go: Never again. Maybe they're better with concrete floors, but in my living room with wooden floor they made things worse, sound-wise AND for my neighbours.

Great information well presented. I found even the most basic decoupling improved the sound of my system. I can only imagine the possibility of using something well engineered for the purpose. I found it particularly revealing when you point out the relationship between seismic background movement and the movement of a cone reproducing low level information in music.

@townshendaudio7867 6 лет назад

In engineering, we are taught to put numbers on things, not just guess! It is quite clear in the video that in the case of a 40g cone and a 40kg cabinet, (floating) will loose 40/40,000 = 1/1000 of the signal, according to Newton's third law (which you quote). This means that the sound level will drop by 999/1000 = 20*LOG(999/1000) = -0.00869dB. I don't think even Gord Thor could hear that. What does go, when isolating, is the resonance between speaker and floor akin to a plucked ruler in a bench vice. The bloom smear and colouration taken away is immediately obvious to all listeners, regardless of the floor or the speaker. Do the experiments yourself. To measure, use Android, playstore, seismograph, Calvico. Max

Have just looked at your video again and think you may have forgot an other clear advantage of your system vs spikes! If your system don't have spikes, your system dos also not put marks in the floor that maybe many while you are adjusting the speaker placement or the marks at the finale placement is getting deeper as the time goes on.

@florincoter1988 3 года назад

To me best knowledge (that may be not very much indeed) the oscillating modes of an acoustic device is function of the boundary conditions. Normally, a loudspeaker is designed with fixed contact points. So, making it float is not a good idea. At least not related to design principles. Additionally, the real energetic ground waves are transversal and in a range outside the human ear. Even assuming that these noise reaches the speaker, it cannot reach the ear as transversal waves are not sustained by air. Just some Physics and some 20 years of experience with positioning of high quality loudspeakers.

@michaelporter1870 3 года назад

Aside from the expense of the Seismic Isolation Podium (SIP), it is too spongy to prevent movement of the speaker cabinet/assembly due to the throw of the speaker voice coil which propagates sound waves unless a sizeable amount of mass loading is added. I would like to see these speakers set up as shown in this demo on a flat level vinyl tile floor driven at 90db pulsed output for various frequencies (start at 50hz and work through the audible spectrum in 50hz increments to 20,000hz) and use a frequency meter (which is insulated from sound transmission through everything except the air) set at 1 meter from the front of the speaker cone which is propagating the sound waves for the frequency being tested, and see what the differences are in the propagated frequencies between the speaker on spikes and the speaker on the SIP. I have come up with a solution which could be used for the speaker with spikes shown in this video for less than $50 + tax: two 2'x2'x2" concrete paver stones (90lb each) approx. cost $16.00; eight spike cones approx. cost $25.00; eighteen 2"x2"x7/8" antivibration pads approx. cost $5.00. Here is how to set up: I have found the best sound from my system is achieved through the use of spikes/discs/antivibration pads/concrete pavers: drive.google.com/drive/folders/1C1w4HcZuThrTxImadujOdftffK3s_2K3?usp=sharing. If you have wood flooring or some other flooring material which is relatively smooth and hard, and you don't want to ruin it with concrete pavers being set upon it, use the antivibration pads under the concrete pavers, one near each corner and one in the center.

@Max Townshend Sorry, you are wrong: if I were to suspend a speaker cone/driver devoid of its holder/cabinet assembly by, say, a string hanging down from a stationary point say 20' above in perfectly calm air and pulse it (when it is perfectly stationary and still) to propagate a sound wave, there will be a forward movement of the cone with a responding rearward movement of the cone/driver assembly similar to a rifle recoil when a bullet is fired. But, unlike the rifle recoil, the return movement of cone rearward will be responded to by the cone/driver assembly moving forward. The very movement of the cone/driver assembly rearward responding to the cone's forward movement will cause a frequency shift in the propagation of the sound wave. If you don't believe this, do the experiment and learn the truth for yourself.

Townshend podiums a lot of money undoubtedly yes, worth it unreservedly recommended the best upgrade I've made. Better than any interconnect stand ancillary. So what do they improve? Everything..! Yes everything. But you don't lose anything its cleaner deeper wider more enjoyable. Mids female vocals are divine all midrange it's cleaner more audible. Top end clearer. What these stands do is take away all the splashy treble all the muddy mids all the boom and bluster in the bass. What your left with is not less but more of what your speaker CAN deliver, which for me is far far FAR away from what I had. So I hear you say what am I using? An all naim pre power with supercap cds3 through focal 948s. All cable is from chord mains and inters and speaker cable. Townshend have long been on my to have list at some point, at 60 years old the journey is far from over, owning an allegri+ in my second system has proven equally as enjoyable.

The frequency would be identical as Newton's 3rd law applies. If you, as you suggest, the frequency changes, then how come the music from hung columns at rock concerts isn't weirdly distorted and lacking in intensity? Antivibration pads are far far too stiff, as they only start to isolate above 30-40Hz- we abandoned that approach in 1985 and went for the very soft springs which are 20dB+ down at 10Hz.

So all about Isolation, what are the differences of just putting it on a big pillow?

@maxtownshend8375 4 года назад

We have been researching this subject for 50 years and have decided that the Victorians had it right by applying Newton's laws and used the mass/spring low-pass filter. A normal big pillow will not hold a 50kg speaker, but if you filled the pillow with something that would hold the speaker, the speaker would fall over. Remedy; you could tie four lengths of fishing line from the top of the speaker to the four curtain rails around your room to stop the speaker from toppling, it would not work anywhere as well as the Seismic Isolators, because the isolators use music wire springs. They work!

There are so many incorrect premises stated here, I wouldn't know where to begin with this video. Just one example. Hopefully, it doen't take a rocket scientist to understand that vibrations and shock / impact are entirely different subject matters and both require entirely different / opposing remedies.

@maxtownshend8375 4 года назад

Shock and impact are just vibrations at a different amplitude and covered under the same engineering analysis

@ToadStool942 4 года назад

@@maxtownshend8375 That's incorrect. Remember that we're generally dealing with sensitive instruments designed for high precision and accuracy. Sure, shock / impact can and will induce ensuing vibrations. If I take a sledgehammer to a vertical support beam in my house, eventually the entire house will vibrate. If it doesn't collapse first. And yes, I'd like my vertical beam to absorb the impact from the sledgehammer. But nowhere in high-end audio are we talking such impact. Unless you wanna include the 400 lbs. guest at a party dancing 3 ft in front of a turntable. We're talking resonant energy originating from 3 primary sources, floor-borne, air-borne, and internally-generated. Nowhere is a source of vibration considered a stomp on the floor or ding on the side of a speaker cabinet as that is not reasonble nor practical in high-end audio. For example. You mention protecting the speaker from the 1M+ earthquakes registering 2.3 or greater on the reichter scale. That sounds fine from a lay-person's perspective, but you make no mention that the speaker itself is the epicenter of its own little earthquake continously generating its own vibrations and associated energy which is far worse the earthquaks registering 2.3 or above. Your "isolation" device indeed protects the speakers from outside floor-borne vibrations but what about all the unwanted energy within the speaker you've now trapped within and must now release all of its energy within the speaker including the drivers and crossover? IOW, you've just trapped all unwanted air-borne and internally-generated vibrations within the speaker cabinet. Unless one only listens to string quartet music at 65db, how have you possibly improved the effects of unwanted energy within the speaker cabinet? Unless perhaps you think air-borne and internally-generated vibrations induce no sonic harm. Mechanical energy's first behavioral principle is to travel away from its point source. But when trapped, the 2nd behavioral principle is to release its energy at the most easily excitable object within that trapped space. Think crossover and drivers perhaps? Moreover, when trapped mechanical energy will often times generate sympathetic vibrations over and above the vibrations already captured. Again, on the most easily excitable objects within. Again, think crossovers and drivers. But then you also talking about objects like a speaker cabinet ringing after being dinged. Indeed. But a plastic spoon will also ring just like a tuning fork when anchored into a vice and dinged. Most any object under stress will ring when stressed. That's just evidence of energy being released. So let me ask you. What does a stressed object like a speaker or even a plastic spoon potentially become when it is sufficiently damped?

@super-z8943 4 года назад

@@ToadStool942 spiking a speaker to a rigid floor does not damp internal vibrations. A well designed cabinet would damp vibrations on its own. But a floor is a lousy resonant system and will repeatedly excite the caninet. Isolation is good, damping ( CLD is even better). But yes, stomping is dramatic but not the best way to demonstrate this. Proper method should be though excitation of the driver itself by sine waves.

@ToadStool942 4 года назад

@@super-z8943 You are correct when you say spiking a speaker to a floor does not damp internal vibrations. I never said it did. Isolation is evil. First because it's impossible to isolate anything from all sources of vibrations simultaneously - though many go to their graves trying to defy basic laws of physics. Second because as Townsend said above, we're dealing with sensitive instruments whose presicion and accurracy are at stake. Sadly the isolationist thinks the floor induces the most harmful vibrations but this is just common folkore perhaps because when taken on its face, it seems to make sense. More importantly, if one were to successfully isolate one source of vibrations, that inherently implies at least one other source of vibrations will remain trapped within and must release all of its energy within. Kind of a pick your poison. If you wanna play vibration expert, you should at least ask yourself what does to a material / object become once it is sufficiently damped?

@super-z8943 4 года назад

@@ToadStool942 Have you ever measured vibrations in a well built loudspeaker? Or are you imagining things in your head? A loudspeaker cabinet is damped in itself. The floor beneath it might not be. Thats why coupling might be a bad idea. Isolation might have only one potential drawback, in that the cabinet moves back against the cone resulting in far less than 0.1dB bass SPL, which shouldn't be an issue. Isolation is always good. The logic is to protect the floor from loudspeaker vibrations, not damp loudspeaker vibrations in itself. Now, there are some rules to isolation. The resonant frequency of the isolation platform (which also depends on the speaker weight) should be far lower the frequency to be isolated. These isolation system you see might have reaonance less than 5 Hz, thats why they are so soft. That is why putting a random rubber piece underneath your speaker might backfire. Don't do it and call it speaker isolation. (You can get away with foamy stuff which creates a frequency dependant isolation with controlled transmission at resonance unlike rubber. Always measure, as it is to naive to generalize given differences in materials and implementation) Now, coming to the 3rd and the best method. Vibration damping using viscoelastic materials. These might work from best to terrible depending on design and implementaion but can be very very expensive. Like I said, always measure. Measurements don't lie. Don't measure with stomps, use actual drive unit excitations. But again, sine waves doesn't tell the whole picture!

@@florincoter1988 Aside from the expense of the Seismic Isolation Podium (SIP), it is too spongy to prevent movement of the speaker cabinet/assembly due to the throw of the speaker voice coil which propagates sound waves unless a sizeable amount of mass loading is added. I would like to see these speakers set up as shown in this demo on a flat level vinyl tile floor driven at 90db pulsed output for various frequencies (start at 50hz and work through the audible spectrum in 50hz increments to 20,000hz) and use a frequency meter (which is insulated from sound transmission through everything except the air) set at 1 meter from the front of the speaker cone which is propagating the sound waves for the frequency being tested, and see what the differences are in the propagated frequencies between the speaker on spikes and the speaker on the SIP. I have come up with a solution which could be used for the speaker with spikes shown in this video for less than $50 + tax: two 2'x2'x2" concrete paver stones (90lb each) approx. cost $16.00; eight spike cones approx. cost $25.00; eighteen 2"x2"x7/8" antivibration pads approx. cost $5.00.
