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.

Have been able to adjust pods on my Podiums and Platform independently for leveling and only issue is the Platform pods need more grip on the bottom and I’ve had to often align each one so they are perfectly vertical. 
What I have learned is that with both products maximizing the surface contact of your loudspeakers, in my case Osiris stands, to the constrained layer surface of Podium/Platform. CD player was problematic due to varying buttonhead screws on the base plate and so began with Rollerblock 2+, various cones, pads, etc.

Today after tearing system apart to apply a annual beeswax to the audio rack I replaced the 3 thin 1/8” stainless plates with 6 Rollerblock Jr. discs (without bearings) evenly under the CD player. This is the best I have been able to do to this point but May still try a set of Precision Couplers as well. The difference each change made was immediately audible and required attention. 
 

Hope this might help others and updated my system page today for those who may be curious. 

tmiddle,

Thanks for the response. Are you sure you are actually adjusting? I have moved the knob(s) up and down and all the speaker does is move with the spring; the overall level doesn't change. The weight of the speaker just re-adjusts.

The Podiums do adjust differently than the exposed pods on the Platforms. With the Podiums you need to use the small wrench provided and turn it while holding the pod stationary. I did use a level when adjusting during installation, but it’s been some time ago. 

Ozzy did you watch and listen 2 the video I posted?  The sound on the video paints a big picture.Tom
