Footers under new speakers

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!

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.

Thank you to everyone, I have a lot to consider. My carpet is too thick for anything within reason to totality flatten it. Also an afterthought is I’m on a slab on clay with next to zero drainage. My floors wick moisture year round and if an area with any size can’t breath it will mold. So I’ll need a spiked platform or something with a box footer and a couple hundred pounds of weight. I have a pair of 14”x14”X4” Timber Nation spiked platforms that I bought for my Zu Omens. They didn’t provide any improvement because for whatever reason my Omens loved the back loading the carpet provided Vs every size gap I tried. Even Sean from Zu couldn’t suggest a fix. It was one of those times a tweak was a huge negative. Is there a spike available for the Townsend Podiums ? Thanks, Mike. 

@buellrider97 Not sure if Townshend has spikes but I don't have them and I don't need them with my podiums.

There's an interesting theory relevant here called the "Theory of More Stuff" 

It basically simplifies vibration isolation abd posits that introducing "stuff" between an audio component and its support surface will always reduce vibration to some degree. 

It dismisses two impossible outcomes: 

(a) vibration increasing (violating thermodynamic laws) or 
(b) remaining exactly the same (unlikely given a change). 

Therefore, the only logical outcome is attenuation of vibration.

Various materials and combinations, from spikes and plates to sand and concrete, can achieve attenuation. And more "stuff" often leads to better results – consider, e.g., stacked platforms.

The goal is to optimize this "stuff" for the best results in the simplest way. 

Historically, the spring has proven to be the most effective solution. A spring, or any compliant material, acts as a mechanical low-pass filter when paired with an appropriate mass. 

The ideal setup aims for a low resonant frequency (around 2Hz horizontally and vertically) and a specific damping ratio (0.16) to effectively isolate audio system vibrations, which typically range from 5Hz to 500Hz. This optimized approach ensures significant vibration reduction.

Thought you'd be interested.

@hilde45 , Greetings and thank you for your input. I’m thinking I’ll need size 3 for the platforms. I saw them on AGON for I think $1700. They look like my top pic so far. I’m feeling confident that I can just run them on my carpet. Also on my spiked ZU’s I ran a 4lb stainless weight at the front edge on top. They are essentially jumbo TT record weights. We’re changing out the nearby 900 sq ft of flooring to glue down oak laminate in about 2 months. The seating area in the room 18’x17’ with the back 10’x18” already wood. Eventually I might go to wood or more likely a thinner dense Berber. FWIT , I’ve always appreciated your input as I’ve watched your system grow. I totally dig your JBL’s and all the effort you’ve put into trying gear and exploring room treatment’s. If I had TMR near by I’d be trying a lot more stuff. Also my kid in Wheat Ridge just put a bid on a second house. I’ll probably be there late fall. I was there last summer but we had a family party there and a wedding in Estes. I was too busy to see any gear. If I see a window when I visit I’d love to meet you. Cheers , Mike B.
