Footers under new speakers

No matter what you do that 1" of shag carpet and padding is going to impact (sic) stability. How about laying down one or two 24" off-the-shelf concrete patio slabs to act as a base? Then add your springs etc.

I'm using the oem spikes which sit on isolation discs.  Basically, two machined discs with carbon ball bearings between them.  My floor is carpet on concrete. I would guess that the discs prevent a lot of bass from going into the floor. 

In the test we did at my friend's room, his speakers were on carpet on concrete, in the basement. We tapped on one speaker (left) and saw a jump on the right speaker, about 8 feet away. And this was with the Gaia III footers. After the speakers were on the Townshend podiums, we tapped again – and saw nothing. Really amazing to see how much comes across even a concrete floor!

Ever watched the videos where Max Townshend setup an accelerometer, A/B ing on concrete floor?

If removing vibrations make one's system sound bad, you have another issue.

In my experience, with modding my VPI Jr. up to Mk.IV status and beyond, decoupling is the way to go.

I bought a Townshend Rock 7, later that confirmed the benefit of springs. Then developed my wall decoupling shelves, integrating Townshend Pods

Tekon sells footers for $20.00. Remember every dollar saved can go to new vinyl.

I know there is a fundamental debate between using traditional spikes and advanced isolation platforms like Townshend Podiums. While spikes have long been a common solution, aiming to "couple" the speaker rigidly to the floor, the podiums offer a fundamentally different and I think superior, approach – decoupling.

Why is it superior?

Consider that traditional spikes concentrate the speaker's weight onto small points so that vibrations are drained into the floor, which then acts as an inert mass. 

But this coupling is a double-edged sword. It not only transmits speaker vibrations into the floor, potentially exciting it and leading to boomy or muddied bass, but also allows external vibrations from the floor (like footfalls or traffic) to travel back *into* the speaker cabinet. This bidirectional transmission can introduce unwanted resonances, coloration, and a general degradation of sound quality. 

Podiums, in contrast decouple the speaker from its environment. They achieve this through a spring-loaded, air-damped system (called "Seismic Load Cells" by Townshend). This acts as a mechanical low-pass filter, effectively isolating the speaker from vibrations down to very low frequencies (below 3Hz). This isolation works BOTH ways: preventing speaker-generated vibrations from affecting the floor and preventing floor-borne vibrations from affecting the speaker.

The other thing I've liked about the podiums is their ability to adjust for height and leveling and the way they can accommodate various speaker sizes and weights, with or without their original spikes. 

My two cents.

Spikes through the carpet/pad making contact with the slab.

Isoacoustic GAIA are my choice, but in your situation frankly I don't think they are your best option.  Of the suggestions made so far I recommend you carefully consider the link provided by ditusa.

+100 on the Townshend platforms. I have a 30 year audiophile buddy who had the Gaia footers and he did a bunch of A/B with the Townshends and they won the day. I have used the podiums with both floorstanders and bookshelves – under the stands. There is really no doubt that these do a lot for the imaging clarity and soundstage width and depth. Easy company to work with, communication wise.

I use Townshend Podiums under my floor standers. Love them.

Read lots of good things on Stack Audio as well.

Although the Iso Accoustic Gaia's are expensive,  they are worth it imo. I put a set under my Legacy Audio Signature SE's and the improvement was significant.  They are sitting on a hardwood floor over a framed floor on engineered wood joists.  So I was getting quite a lot of vibration and standing waves, They are a bit pricey,  but very effective on all types of floor construction.  And remember if you ever upgrade your speakers you can switch them to the new ones,  so it's a long term investment. 

Use the spike that came with the speakers and go to IKEA or Any stores that carry bamboo chopping board put it under the speakers. My ps 12 tekton are happy.Teajay used them for his ps12 when we visited Him.

Put the spikes on and put a penny under each one. It should work well enough to get by while you're looking into different options. It will also serve as a reference.when you try new feet/spikes.

+1 on the Townshend Audio Seismic Isolation Podium for Speakers.  I have them and can verify what is published on their performance and improvement to all SQ attributes is true.   Not inexpensive but worth the spend.  

Just installed my Auva 100's on my Legacy Focus Se today. I also have the Smoothlan Regenerator. Great company.

I think when you get all the inputs the likely consensus will be: Townshend Audio Seismic Isolation Podium for Speakers. By far they are the most highly regarded speaker stands. While I do not have them I know many people that do, and I don't think I have ever heard anyone ever say anything but extraordinary praise. Hmmm, I guess I need to put them on my list. Don't actually know why I don't have them.
