An alternative is to use size AAA batteries. It is essential that they are parallel to each other and that they are placed on a hard, smooth surface (plate glass is best). They also MUST provide front to back freedom which is in exactly the same direction as the cone's movements. You must first peel off the outer paper/plastic so that the metal can is fully exposed and clean of lumps and bumps. I no longer bother with such niceties as my hearing has degenerated so much that the benefits of such work are subjectively so marginal as to be no longer worth the effort. I do still use carbon blocks under all equipment and this is worth the effort. the floor of my room is fully floating and the hardware - other than speakers - is in an adjoining room.

I used to peel off the aaa's and then paint them in mat black varnish.... When I was young and bold.

I will of cause not show the squeaky yellow tennis balls in public. They stir much too much attention.
Here is the " beautified " version. I spray them black and put them in a silicon rubber hose. That hose also helps to stop the tennis balls rolling but does not affect the vertical decoupling much.

Of course the question on everyone's mind, is selecting the very best sounding tennis balls!
They come in three varieties, so which is best?
Grass Court?
Clay Court?
Concrete Court?


P.S.
Here's a photo without the yellow. They don't seem to collect scrutiny when the color is light/medium gray.

I could only get that type of tennis ball in the small town i life.
I have no doubt that different varieties sound different. Also the silicon hose made a difference. It sounded more snappy and dynamic.

Does the ATL have a patent on that? (Provided by Obi-Brilon I think (the brother of Obi-Wan Kenobi - Wikipedia, the free encyclopedia)).

For a patent it is too late but i will not disclose the proprietary technology to get the ball in.
