Hi all,
I'm new around here, so mods, if this is an inappropriate post, please shut it and pm me. I don't want to break any rules. I will state up front that the purpose of this post is to ask forum users about a commercial idea. If i am breaking rules, please let me know how best to go about it.
As we all know, speaker isolation pads have been around a long time. The intention is obviously to mechanically decouple the speaker from whatever it is standing on.
The problem with existing speaker isolation pads is that there is no clear data supporting their performance. Manufacturers seem to choose a foam or rubber at largely at random or what is available to them. I am interested in challenging this idea because of a special material i have access to. It's called Sylomer and has been used around the world for isolation vibrations.
What is special about Sylomer is that the stiffness of the material can be selected based on what you are trying to isolate. The guys in Austria have isolated everything from mills and turbines to studios and speakers. And on each project, they managed to tailor the material to isolate the resonant frequencies that are causing the problems.
So, here is the idea, and all your feedback would be greatly appreciated:
I want to manufacture locally produced speaker isolation pads that use Sylomer as opposed to whatever standard rubbers and foams have been used in the past. The isolation pads would be similar to some others that have been manufactured before in appearance, but their performance would be tuned to the following categories:
1. Bookshelf Series
2. Floorstanding Series
3. Large Floorstanding Series
Attached is an example of how the pads would behave with a B&W 683 sitting on top:
You can see the following:
1. The natural frequency of the isolator is 14,1Hz
2. At 20Hz, there is 0% attenuation
3. But at 25Hz, there is 51% attenuation
4. At 31,5Hz, there is 74% attenuation
From there on, the mechanical isolation just gets better.
How we do this is we calculate the correct size of the load bearing Sylomer element, and work out the correct Sylomer to use. In this case, there are two load bearings Sylomer strips under an anodised steel plate, with a B&W 683 sitting on top. The approximately 27kg load of the speaker causes the material to compress 1,6mm. So in a manner of speaking, the 683 is almost floating on a cushion of air, and the music would have to cause more than 1,6mm of movement for the vibrations to pass through the Sylomer.
We can achieve the same thing for bookshelf speakers and large floorstanding speaker like the 800 series.
I would greatly appreciate feedback from everyone. Questions, opinions, all are welcome.
Again, mods, if i have broken rules, please forgive me and direct me the right way.
