Tekton Double Impacts

@brotw   Thanks for the added perspective. It's very helpful. Always good to know and hear more about takeaways based on what we are communicating and reading in these posts. As all of us are different our interpretations will be different as well. In this case, I can see myself coming to the same conclusion as you did. As @vitop mentions, you'll have a really good feel for these aspects of the speaker for yourself, apparently in short order! : )

Like mac48025, I'm also using Herbie's Gliders. I went with the 1 inch length for the threaded Giant Gliders since I didn't need to adjust height or tilt and wanted stability...the Gliders are flush with the speaker base. If you want the flexibility for tilt and height, the 1.5 inch that Mac is using would be the way to go. I also find that raising the speakers off the floor improves bass.

I'm using a set of the non-threaded Giant Gliders under an isolation shelf. The speakers with the threaded Giant Gliders sit on this shelf/Glider combo.

@david_ten I was thinking taller feet as well as I had similiar results with some large Jamo Cornet 100's back in the 90s. There were no feet, so used brackets and JB weld with threaded rod and caps, a college upgrade. Bass tightened up nicely. 

Your comment on doubling up the isolation with shelves and additional gliders had me recall the Townshend isolation speaker platforms. The price has me looking for other tweeks. Is your isolation shelf basic mdf or something fancy?

What are those speaker stands that @teajay uses? I forgot. I should have bookmarked the site. 

Thanks Charles. I'm hoping to make a number of system upgrades in the next couple of months so there will be plenty of reasons for you to stop by to listen. No need to invite yourself as you have an open invitation!

evolvist, I believe teajay is using the Sistrum speaker stands. Charles uses them also. They are sweet looking. 

@brotw   The shelf is a synthetic composite. Was a one-off isolation rack made by a Japanese company. The only reason I'm using them is because I have them and I may as well put them to use. I also have another one-off carbon-fiber with honeycombed-center shelves, but I don't believe they would support the weight.

I'm sure any isolation shelf / material that you find has been helpful in the past would work. 

I've been in touch with Star Sound Technologies (they make the Sistrum and other platforms) to come up with a stable solution for my needs. Their platforms and isolation for speakers are well regarded and they have been a real pleasure to work with. The holdup has been getting a blue-print of the speaker base from Tekton which I hope to have soon.

Another option I'm considering, as a direct comparison to what the Herbie footers have delivered, is IsoAcoustics, specifically their Gaia speaker isolation devices/footers. They are slightly more expensive than my Herbie's solution (16 Gliders) vs 8 IsoAcoustics footers. I'll likely continue using the base shelf + Herbie Gliders with the IsoAcoustics threaded into the speaker base standing on the platform/footers. This will give me another inch of elevation over the current setup.

Other DI owners are happy with Soundocity outriggers, in case you want to explore this option.
