Experience with Townshend Seismic Podiums on Concrete Floor (they're great)


​I have tower speakers on a concrete floor covered with carpet. Recently, I tried out the Townshend Seismic Podium (size 1)  on my Ascend Acoustics Towers (RAAL tweeter) for about 4-5 hours. Here is a brief recounting of my experience.

At first, I set up the podiums and just listened to well known tracks; next, a few days later, I used that same set of tracks to compare, A & B, the speakers on the podium vs. without the podium (but at the same height). A friend with me also compared this A/B setup. We listened to a simple jazz arrangement, a Mozart aria, a rock recording by Chesky, and a country/rock piece. All were well recorded.

The difference made by the podiums are not subtle. In general, it is as if the entire sonic presentation was brought into focus, as if a light veil or layer of dust had been wiped away. It organizes everything; it makes the parts of the whole make sense.

More specifically, these were the effects I noticed: 

Bass was slightly fuller, much cleaner and more distinct; for an electric bass, this meant that rounded notes that previously blurred in a sequence (too legato) become individual notes. String bass notes gained dimensionality and texture; the finger on the string became more real, and the resonance of the large wooden bass got fuller and richer. Rhythm sections were better able to stand out *as* rhythm sections, that is, as musicians who are working together.

As far as midrange and treble go, there was -- as with the bass -- more definition, clarity, detail. They sound more like instruments-in-the-room rather than the presence of instrument appearances. Not much about their tonal character changed, but they became more palpable and more exactly located.

That brings me to the soundstage. The width of the soundstage grew by about 10-14% — 5-7% on each side. It was remarkable. Instruments gained space, separation, and definiteness of location. They didn't sound apart or isolated but just more distinct, separated from other instruments. I imagined this as fidelity to the way the microphone recorded them or as the mixing engineer intended. 

When I ordered the podiums, I made sure to ask for the ability to return them. I was assured that I could return them if I just paid shipping. (No restocking fee.) I was skeptical and wanted an escape clause. I had watched a few videos and was curious about whether Mr. Townshend's scientific claims would translate into audible differences that would be worth the money (the podiums cost about 1/3 of my speakers' cost). 

Well, my skepticism is gone — and it disappeared rather quickly at first, and then after careful comparison. I am keeping the Townshend podiums. Are they better than Isoacoustics footers or other products? I don't know, because I have not compared them. But they're making a huge difference and, should I want to put other speakers on them, they'll fit the others I have, easily. I'm pretty sure I'll never give these up.

I have owned the Seismic platforms for a couple years and they are transforming .

Prior to the Podiums I was using spikes with Combak Harmonic footer. 

It is one of the few audio products that is universally praised by people who actually own them. Yes they are expensive but chances are they make up less than 10-15 percent of total system cost. They’re improvement is actually a great value. The beauty is every single piece of your equipment benefits and changes in cables,fuses,power supplies, are much easier hear. 
My biggest takeaway from them are the space around the instruments and not only the depth of the stage but the actual placement of the players. Live recordings are especially impressive as you will hear the audience in front and the singer a few feet back and guitar player a couple more feet back and to the left  and the drummer 12 ft behind the singer but 8 ft behind the guitar player etc. I guess you would call it layering . 
All the other goodies apply, texture in vocals, improved bass control, etc.

I do have a golden ratio room which helps, it is a converted garage with a cement floor. 2x12 floor joist filled with foam built on top of the existing cement slab. I knew where my system was going to be so much more than typical cross bracing etc. 

Finished flooring is LVP with cork backing . It floats so probably not the best but it looks great and easy to take care and self installed   Could be another reason I felt I had such an improvement with the Podiums  

The Townshend folks are awesome to work with and will work hard to make sure you can afford your Podiums . I went thru all Herbies, Stillpoints,Combak Harmonic ,chain . Save up your money and buy the Townshend Podiums .You won’t have to worry about selling them for 50 cents on a dollar in a couple of years!!

 

 


 

I watched the video on my big system. Really liked what I heard. I am sure part of the reason was the podiums allowed me too. If they do that for an amp I can only imagine what they can do for a speaker. 
I checked the exhibitors list at Axpona and don’t see them there. Maybe a dealer or  someone else may be using them. 

@laynes. So you have them under your Spatial speakers? 
My buddy has a pair of X5’s but looking at them I wondered how a podium would work because of their wide footprint. 
Glad to hear you are enjoying them.  Well worth the investment 

Nice fit for your speakers. Townshend makes a great speaker cable called a Fractal F1.  Its as good as a cable as the Podiums are for vibration.
