Townshend Audio Seismic Podiums Review


Seismic Isolation Podiums: A Game-Changer for Bass Control and Overall Sound Quality

After attending the Capitol Audio Fest, and returning home to evaluate my system against what I’d heard, I was reminded just how much I love the sound I’ve cultivated in my setup over the years. In many ways, it stood up favorably against some of the best systems I heard at the show—some costing many times more. That said, the experience left me inspired to try to push my system further and find how I could make it even better.

One issue I’ve been wanting to address is the bass boom in my room caused by my large speakers coupling with my raised floor. My listening room is on the lower level of a split-level home with an open floor plan and a suspended floor that behaves a bit like a drumhead. While I’ve installed bass traps in the corners and experimented with absorbers and isolators, I was still searching for a way to decouple the speakers from the floor entirely.

That’s when I discovered Townshend’s Seismic Isolation Podiums. I was already familiar with Townshend’s supertweeters, but I had no idea how highly regarded their isolation products were. After combing through countless reviews (seriously, I couldn’t find a bad one which was amazing), I reached out via an Audiogon listing to Townshend’s Worldwide Sales Manager, John Hannant, for guidance. He’s a really responsive guy, and he recommended and sold to me the Size 5, E-weight Podiums for my massive 250+ lb Dynaudio Consequence Ultimate Edition speakers.

The Podiums arrived in Virginia in under a week, all the way from England, and my first impressions  were:

1. They’re frickin big.

2. They’re frickin solid.

3. How on earth am I going to get 250 lbs speakers onto these spring-loaded platforms

Thankfully, the process turned out to be much easier than I feared. Using Teflon furniture sliders, I carefully tilted and slid the speakers onto the Podiums, fine-tuned their positioning, and bubble leveled them according to the directions. Despite how unnerving it feels to see, and feel, my hefty speakers perched on a bouncy interface, the results speak for themselves: the bass response has been transformed.

The muddying boom I’d been battling is gone, replaced by bass that is tighter, quicker, and far more defined. It’s truly amazing how much of a difference these Podiums have made. Beyond the bass improvement, they also reduce vibrations transferring from the floor to my equipment rack, which further improves other aspects of the sound in more subtle ways. Everything is just a little better.

The build quality of the Podiums is exceptional, as you’d expect from a product hand made in England essentially of just heavy specialty coated steel, carefully chosen tempered springs and a custom rubber dampening system.  While they’re not inexpensive (what is, in this hobby/industry), they deliver on every claim I read about, and can be considered a lifetime investment because there is nothing to wear out.

Townshend has truly created a stellar product, backed by fantastic customer service. The Seismic Isolation Podiums have exceeded my expectations, and I can’t recommend them highly enough to anyone looking to elevate their system’s performance, particularly if resonance is a known issue.

Kudos to Townshend for such a well-engineered solution that makes a real difference!

Note: I have no affiliation with Townshend, nor was any monetary or product provided to me to generate or influence my review.

The Townshend web site has links to Mr. Townshend showing significant vibration absorption even directly on concrete. That said, my implementation was to try to solve an audible problem with a crappy floor that the stands seemed tailor made to fix. I have no idea how much difference you would hear/feel in your application on what should be a good floor situation. Maybe play some reasonably heavy bass and actively try to feel how much vibration is transmitted directly from the speakers to your flooring, and from it to your gear. With the Townshend’s, I can stand barefoot right next to the speakers and feel nothing, up to a pretty decent volume level. That was not the case before them.

@hollandw I had the same situation as you.  I tried spikes, no spikes, gliders, and limestone platforms.  Nothing worked until I got the Townshend podiums and acctually de-coupled the speakers from the floor.  I sold all of my other "isolation" devices and use the platforms under all of my equipment.

Having twice moved into homes where I picked the basement for my listening room, I found that, right off the bat, music sounded better on the concrete basement floor than on suspended wood floors, even one room where I built as ASC Wall Damp system. I accounted for everything but the (springy) floor. Interestingly, when I lived in San Francisco, I lived on the first floor of a 2 family home, and that floor was completely solid. That was probably due to the San Francisco Earthquake of 1906 happening 5 years before that house was built, so probably construction was much sturdier after that seismic event!

The listening room in Connecticut was surprisingly mediocre sound-wise compared to the basement immediately after the Room Damp treatment and I moved into the room. I eventually got around it, but after moving down the Eastern seaboard yet again, and moving into the basement, I noticed immediately how ’solid’ the sound was overall.

I would think the concrete floor should eliminate the need for the Townshends (I have Townshend’s iso pods and a Seismic Isolation platform for electronics), but I could be wrong. Hollandw seems to have had great success with them, and Townshend's products work. The thing is whether they are worth it to you. If you’re at all able to try them out, that seems to be the best way to go.

I have a suspended floor. I'm using Podiums under my Usher Mini 2 Diamonds. They helped the speakers to disappear even more when listening. They do have a large footprint. I'm a big fan of Townshend products. Using Pods in my DIY wall mounting system. Even own a Rock 7.
