Speakers on speaker stands-isolation ideas?

Vibrapods have been the best for me...and I have tried many things under my monitors with varying results.

Some valid points. One thing I like about the Acoustech pucks is they grip the speaker quite well with practically no damage to the veneer. When I lift the speakers off the stands there’s a fair bit of resistance - not enough to withstand a forceful and deliberate push , but enough to withstand most accidental bumps and earthquakes.

I've been using them with my Walnut Spendors for over a year and there's only the slightest discoloration where they contact the speaker.

These cost me around $100 each. They are without a doubt one of the best and most cost effective additions to my system. I even have one of these sitting under my REL Sub to great effect.
 

I know we're talking sound here, but I have to again mention safety.  A painter knocked over one of my Opera Callas monitors held to the stand with Blu-Tak.  I was able to grab the unit by the speaker and the stand and speaker stayed together as one.  Of course my dog happened to be laying exactly under the speaker and would have been injured on killed had the speaker not been secured to the stand.  Keep that in mind.  As a bonus, it may yield the best sound as well.  

@amg56  I know you are but what am I?

I had to look up Sorbothane on the net. I've never heard of it before. It could be marketed in Aust. under a different product name.

That’s odd. Sorbothane has been part of the audiophile vocabulary for what, gotta be 30 years. Has Aussie land been cut off from communications?  😀 In my opinion Sorbothane is probably best relegated to its original intended use as shoe insoles.

Thank guys. That's cool stuff.

I received what looked exactly like the  Acoustech Speaker Dots with my new Sound Anchor Signature Stands that I use with my Aerial LR5s.

Check out seller "dang-good-stuff" on eBay for genuine affordable Sorbothane materials.

You can place it between the speaker and stand instead of blue-tak. Just recently bought some to isolate bookshelf speakers from a resonate office table they sat on and SQ improved. Comes in 3 densities, 30D, 50D, 70D, get the lowest value that will still support the weight of the object for best isolating effect.

For people using stands on carpet, many people have recommended spikes under the stand into the carpet.

+1 on the Sorbothane pucks.

I like these Acoustech Speaker Dots:

They’re the Sorbothane pucks that come standard with Sound Anchor stands. I’ve found nothing that "sounds" better.

Check out Herbie's products.

I put some self-stick felt pads on the top of the stands, under the four corners of the bottom of the speakers, that seems to work well...in addition to filling the stand's upright with sand.

IMO, you are approaching this the wrong way by assuming "isolation" as you call it, will yield a sound that is more preferable to you.  I'm a big fan of standmounts and I have consistently found that each speaker requires something different to adjust the sound to your preference.  You must also consider safety, as putting a speaker on a stand with no attachment subjects it to being knocked over.  But rather than think of isolation, I would first try the speaker on the stand with something like Herbie's black dots, then with Blu-tak, then with some hard interface - I've used casino chips, and see what sounds best.  Same thing with the stands.  Try spikes, try Herbie's Ebony Domes, which are also good under speakers, but allows them to move around.  I don't even think isolation is necessarily desirable.  I have found the stands to greatly influence the sound of the speaker, almost as if they are a part of it and sometimes coupling the two units as one yields the best results.  I think. 

I use Sanus 22" Steel Series stands topped with IsoAcoustic Aperta stands for isolation. Works quite well I must say.

That’s not a bad idea. Gelatin. As in Jell-O. Of course, you have to work out the engineering details. Speaking of Jell-O, of the major food groups Spam seems to offer the best of all possible worlds when employed as a damper. Not too hard, not too soft. And if it doesn’t work out in your system you can make sandwiches out of it.

How about putting a block of ballistic gelatin under each speaker? Should offer real good isolation!
