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.

It is one of the few audio products that is universally praised by people who actually own them.

 

I agree the overwhelming proportion of reports on the Townshend isolation base/bars are positive.  That's one of the reasons I tried them (Isolation Bars).

Unfortunately I found they weren't to my taste.  I lost a bit too much "room feel" in the bass and they changed the tonality a bit more than I wanted, and also reduced a bit of the "body" of the sound.   My speakers sounded a bit more tonally full, dense and energetic without the Townshend bars so I returned them.

Most people keep them, though.

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.

 

 

Regarding raising the height of the speaker/tweeter:  Yes that certainly is an issue, and in many speaker designs it will change the sound.  Sometimes a speaker will sound more mellow and rich below the tweeter, but sometimes it could be a bit more recessed or sucked out sounding.  Depends on the design.

My Thiels sounded more lightened and hollow when raised a couple inches with some (cheap) spring footers.  I just tried Gaias under my Joseph speakers and because I couldn't get the original spikes off the Joseph I tried the Gaias under those spikes, which raised the speakers about 2 inches.  It didn't work.  The sound got less focused, more smeared, and a bit too mellow in the highs.  However I DID like the slightly higher soundstage.  I experimented and found a compromise that raises the speakers about an inch or so, and I like the sound this way.

One of the selling points for me was that the Townshend speaker bars wouldn't raise the speakers which would hopefully not change the tonal balance of the speaker as I was used to.  They worked quite well in that regard - the sound didn't change nearly as much as the higher spring footers or other devices I tried.

(Though, as I mentioned, in the end I still preferred the speakers on the floor, or in the case of my Thiels, with the Gaia...even though there is a slight change in tonality).
