Vibration isolation or absorption?


You see those pointy things at the bottom of a speaker that are very very sharp.  Arguably a weapon in the wrong hands.  And then you see those same pointy things inserted into a disk.

So the pointy things, aka ‘spikes’ , can Channel vibration elsewhere and away from the components and speakers, or they can isolate it.

Seems channeling vibration away from a component/ speaker, which I guess is absorption, is preferable.

Is this true? And why do they keep saying isolation.

Sandwiches to the Rescue.

My Springy wood floors are problematic. I ended up with the Vintage JVC TT with very heavy 7 layer plinth.

Next put TT on these, a trial, they luckily were just right.

So, the TT/Plinth/Adjustable legs were essentially solid, thus Stylus/Arm solid for play.

Then, below that, some rubber/cork blocks allow/minimize the effects of the springy wood floor, to the point that vertical vibration is dealt with, to a degree that allows me to get a step or two away while the stylus drops.

Apply the sandwich to Speakers, rigid (speaker bottom or platform if enclosure not very solid, on flexible (just enough) to isolate down/up vibrations

 

You have attacked my honesty. That aggravates me to no end...

No, Robert, I haven’t "attacked" your honesty, I have exposed it. That you would again play semantic games in an effort to serve your thinly veiled marketing purposes confirms it as a running theme in your posts.

Regurgitating your resume, and various assertions relating to the success of your products, is not only a red herring, but also notable in that I have never said anything negative about them.

In stark contrast, you seem to feel the irrepressible urge to attempt to denigrate the products of at least some of your competitors. It wasn’t enough for you to suggest, ludicrously, that there is no meaningful distinction between coupling and decoupling devices, you had to go further and assert that only the former fall into the category of "accepted science"! And apparently even that was insufficient, as evidenced by this petty, and frankly pathetic display:

Max jumped up and down on the floor displaying his top-of-the-line product and comparing it to a few dollars worth of cheap spikes.

Never mind that Max isn’t around to defend himself, or that his isolation products are held in very high regard by many audiophiles and professionals in the industry, the overriding point is that those who have real confidence in the products that they sell, and themselves, almost never feel the need to stoop to such tawdry tactics.

Everyone who has been in the game for some time understands that there are snake oil salesmen, and that many products sold represent poor relative value. That’s not news. But when you say this:

There is more marketing versus science going on in the decoupling world.

it is yet another example of your attempts to sell your own devices by raising dubious questions about the validity of those employing different designs. And it bears repeating: Given that high-class manufacturers including Marten, Wolf von Langa, Spatial, and Dynaudio are including such products with some of their models, it simply isn’t credible to suggest that those products somehow lack real-world efficacy.

Well, add the price of wrapping the edges with black tape to make them disappear:, let's say an even $13.00
