There are lots of different types of "sand", including various sizes and shapes of the aggregates, not to mention the constituent materials, themselves. I thought that in most cases the idea of in-frame sand is to quench/diffuse "ringing", not ULF. O...

[quote user="Romy the Cat"]Sand damping it beautiful, it is well-recognized, but you do pay cost for it, in your case the cost is space. [/quote]I know that Romy… but without the massive amounts of sand, there are always some vibrations felt when I t...

Ric, I will not be using sand for decoupling. In fact I fill that sand is not good load bearing decoupler as I will have more or less point loading and sand will not work. I will be using sand for damping the horn surface, primary atop of the horn. A...

Jessie, I love the way you have got it so you can EASILY move anything in any direction. I imagine this will be a key in maintaining your sanity as you and your system evolve together. And I agree with the form-follows function aesth...

I thought of filling with sand braided multifilament nylon cable sleeving (http://cableorganizer.com/nylon-multifilament/) which comes in 2 inch diameter and does not expand enough to allow coarse sand to come out. It can be wrapped around as densely...

[quote user="decoud"]For sand to work here in friction does it not have to be load bearing itself: i.e. inside a steel cage that propagates the vibration through the walls there will not be much friction, no? What you want is a sandcastle.....[/quote...

Hello Haralanov,That's a nice strong heavy box you have there.You might want to check and add some more sand in the future because vibration helps the grains to adjust which in turn reduces volume.[quote user="Romy the Cat"]10) Do you know that you...

As I told the design requirements were to makes the horns fillbale with sand. So I did it with one horn. I still keep shaking it rotating it to settle the sand down. So felled up one horn, it took 57 pounds of sand. Add to it 20 pounds of own mass ma...

I used to have a rack where sand was placed inside the structure of the rack (square pipe) and then I would insert a rugged construction rod inside it so it would be "suspended" by friction inside the sand. It didnt work, there was no advantag...

[quote user="Romy the Cat"]Anyhow, now the back chambers are done and the 40 bags of sand (300 pounds) are prepared to be loaded to the horn’s top. We are back on the schedule. When the horns will be installed I will fine-tine the Fs by pocking the s...

[quote user="Paul S"]Again, you might gain something by fastening the rack to adjacent walls and adjusting the tension and/or damping of those connections. In any case, you'll want to prevent swaying of a TT support, and likely a CD transport, as wel...
