Tekton Double Impacts

It sure makes things confusing bliptrip. I was all set on buying the Gaia II's when calling Music Direct. From what I gathered talking to the tech rep is that the Gaia II's will work with the DI's.......just not as effectively since they would be compressed so much they wouldn't be able to disappate vibrational energy as well. He wasn't pushing to sell the Gaia I's so much as he was explaining that isolation devices as a whole don't perform as well at their upper weight limits. I certainly didn't want to spend the extra money on the Gaia I's but after hearing them on the DI's I'm glad I did. 

@bliptrip   I had the same concern regarding the Gaia II with the SE, being that the SE comes in right at 120lbs. I do have them screwed into the base of the SEs and I have noted an ever so slight upside over my Herbie's system. I have not used them on the DIs, but I will prior to sending the Gaia IIs back. [Please Note: They are on my base with Herbie's Giant Fat Gliders; See Below]

@brotw  My Herbie's 'system' is comprised of the Herbie Giant Fat Gliders under a composite isolation platform/shelf that was designed for a rack. This shelf is 18X20X1 inch and fits the DIs and SEs perfectly. 

Here's what it adds up to for each speaker: 4 Fat Gliders under the shelf and 4 Giant Threaded Stud Gliders screwed into the base of the DIs (where the included spikes would be screwed in). This came to $464 for the 16 Gliders (both speakers). Add the cost of any isolation platform you choose to use.

I like this setup for a few reasons:
  
1. I can move the entire system around without removing the speakers.
2. If I remove the speakers, they still have the gliders on, so moving them separately is very handy.
3. I found that doubling up resulted in better results than only with the Gliders in the speakers (this is how most would normally use the Gliders)
4. It adds over an inch in height over just having one set of Gliders in, which I find helps with the bass performance.
5. I can play around with different bases and base materials if I want to.
6. I can add something like the RollerBlocks discussed above in the thread. I personally use Ingress Engineering's bearings and cups for components. I have not experimented yet, under the speakers or under the platforms, but I will in the future. Putting them under the platform would preserve the finish of the speaker base.
7. The platforms I am using match the finish of the DIs and the SEs and are therefore a hit aesthetically.

****Please note that I have hardwood flooring and no carpeting or rugs underneath.

David, Thanks for sharing your set up. For us with carpet, the alternatives to Gaia footers are more complicated as a spiked end point with absorptive material or roller ball somewhere in the chain is desired. There are ways to make this happen (mapleshade, rollerblocks, ingress bearings) but I'm leaning toward the simpler Gaia approach or go budget with Herbie's threaded glider approach (on carpet).

Townshend Seismic Isolation Bars? Anyone using them with the DIs or with previous experience / exposure? Thanks.

@brotw  Herbie's does offer Cone / Spike options for carpeted flooring.
