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.



@hilde45  - I would be the Symposium platforms are better for distortion/noise drainage and the Townshend podiums are better for isolation. I needed more isolation for my turntable and drainage for my speakers, so that's why I use both companies. For speakers, I think Symposium provides a much bigger bang for the buck. If I remember back when I got them, the Townshend product that would have worked was about 2-3 times the cost, and I am sure would have been an improvement - I was just not comfortable with the rocking. My amp and preamp move around with so much as a nudge being on top of the rollerblocks, but I can live with that since they are very stable. 



Great news. Your experience just adds to the statistics and reinforced my belief that the Townshend Podiums register a 100% success rate with those who have tried.


I think you must have missed my post.


Informative video from Credo Audio Switzerland that compares spikes to their own isolation and that of Townshend Audio's.

The key takeaway here might be that isolation products do not alter frequency response unless you want to include major structural and cabinet resonances as part of the audio signal.


@cd318 Thanks. Just watched that video. Very interesting and it seems to advocate for both their custom product and Townshend. @brownsfan may be interested in this one.

I've seen that video and wanted to share it on your other thread but I couldn't remember the company name to find it again. It is very interesting and inspired me to explore different options for my speakers and subs.
