Does anyone use wood for vibration control?


What kind of wood have you found to be best?

I tried wood many years ago when a few supposedly knowledgeable guys said wood is the way to go. In a word, no.

The good and bad of wood is each type of wood has its own characteristic sound, which can be changed or tuned to some extent by varying the shape, size, dimensions and construction. Laminate, for example. It should come as no surprise I guess considering how many wooden instruments there are that a lot of people like the sound of wood.

But that's the bad of wood as well. It definitely imparts a sound of its own. Everything does. Concrete. Rock. Metal. Acrylic. Glass. Everything. Tried em all. Why I got what I got. Very little of which is wood. Turns out I like the sound of wood- in a violin. Not in a rack, cabinet, etc. When it comes to vibration control it turns out I lean more towards eliminating than tuning. That's after having tried a whole lot of different materials.

If you're wondering how that's possible, to have tried all that stuff, well its like this- each material has its own characteristic sound. Therefore its not necessary to make a whole complete rack, shelf, speaker, etc. You can simply test a small square or oval piece. Because what you will find, if you actually do this (hardly anyone does, lot easier talking than doing) you will find that while yes indeed it is a little different depending on size, construction, etc, that the fundamental character always remains.

This is why so many speakers are made out of laminates and MDF. These take the good qualities of wood, average them out, and give you something a lot less identifiably woody. But its still there, which is why pretty much all the very best speakers are composites.

Which is what works best. Except unfortunately DJ passed on so no more BDR. So you are on your own. At least I saved you the time you might have wasted on wood.
I’ve had excellent results with maple and Mpingo discs which are Gabon ebony and African rosewood. But I agree with the previous post that wood can be tricky to work with. The reason you don’t see any cones made of wood with a couple notable exceptions is that wood is relatively soft and will therefore store more energy. Thickness is an issue when using wood for support as thicker boards will resist bending forces better than thinner boards. Note: thank goodness there are no more carbon fiber cones. No offense to anyone. Just commenting on the material, too soft and too funky sounding.
