Default It Is Not That Difficult.....

I've tried three under my CD-94 and it did make a nice difference.
I also have three under my tube reciever and they make a nice difference there too.

If your rack is suitable, I've had success with hanging equiptment from tension springs attached to the shelf above.

Nylon monofilament works well too, especially if you can attach it from the top with 4. I think it works similar to rollerblocks as the motion would be about the same. If the filaments are a bit buzzy, clamp lead fishing weights onto them to change the resonance/damp it. If you have the equiptment positioned only a couple of mm from the shelf below, it looks like it's resting on it, so it doesnt look to strange or tweaky, because you can't see the monofilament.

Default Gone Fishing.......

Nah, not suitable in this case, at least not for speaker cabinets.
Years ago (20+) I mounted the edge of a board against the chimney brickwork, and ran two threads of strong fishing line (monofilament) from the brickwork down to to the outer edge of the board (at about 60 degrees) and placed my turntable on this arrangement.
As I remember this gave absoloutely no acoustic feedback, and you could jump all you liked on the floorboards without disturbing the turntable in the slightest, and it did not look look strange or tweaky in the least.

Hi,

Anything in the monofilaments?

Just a little Q:

When you use springs,are these conical or straight coils?

I think you know what I'm getting at

Cheers,

Default Just Put Cones Top Or Bottom.....

Hi Frank,

The coil springs are automotive valve springs - straight wound and ground flat and square both ends.
Using some kind of conical wound spring would minimise the contact area, and this may be a benefit.
So far the flat ended ones work fine for me, and give good lateral stability AND you can get them for FREE from any motor mechanic.

Eric.

Default ROCK&ROLL SPRINGS

Hi Eric,

I thought as much.
Rocker valve springs they're called, I think.

What I had in mind is the same strength (Q) spring but conically shaped so you can put them wide side facing down for increased lateral stabilty.

I have no idea if such a model is used in automobiles though.
Maybe you came across any?

The idea apeals to me since this is what we used in a TT design many moons ago.
It worked well then, hence.

P.S.Noticed how I paid attention to the spacing after the comma?

Default Cone Then ?

I do not know of conical wound valve springs - only seen straight ones.
Glueing a cone to one end might be a good soloution.
They come in different weights - maybe usefull to visit a motorcycle mechanic for smaller ones.

"P.S.Noticed how I paid attention to the spacing after the comma?"
LOL

Eric.

Hi Eric,

Same here.
The ones on the TT looked as if they were from some automotive application.
No idea where on earth this would be used in an engine though.

I am afraid it would make the whole thing tilt sideways when loaded.

What I had in mind is a metal triangular frame with three predrilled holes in it and then fix the springs underneath with bolts to support heavy cabs.
The top should then fit flush underneath the cabinet.
In that way the springs won't get lost in transport and a product could be put out to the market after further development.

I don't dwell in those circles anymore but since you do?

Ciao,
