Speaker Isolation tweaks ?

I use  under my LaScalas. The good thing is that their adjustable for uneven floors, plus they tighten up the base.

Under my MK subs, I use what skeptikal suggested, the  SVS SoundPath.

Under my (8) other speakers, 3'' Maple from a well known fabricator on many forums, with Mapleshade footers.

Spikes are able to be used and the Floor Protected from Point Loading Damages if the Spike is seated on a Pad as shown in the Link, which is reasonably cheap as the solution.

Any hard materials resistant to the Point Load will be suitable as a Separator from the Hard Wood Floor.

Once again I bought the ISO pucks. I didn't want any adhesive sticking to my speakers. These pucks have suction. So I'm going to put them underneath the speakers and stick with spikes and get feet for the spikes. I guess that is another discussion..... Spikes with feet on hardwood floors GOOD or BAD ? Maybe just a screw with a flat end instead of spiked end ?

@lanx0003 there is a saying: don't buy a Ford at the Ford dealership, buy it at Kia The latter will want to get rid of it fast and cheap. Audio equipment is like a wedding cake, it's the same cake but 10 times more expensive than a "cake". A piece of rubber for a furniture foot is $2, for a turntable it's $20. I think vibration control is the most insane part of audiophilia.... 

+1 @pindac Outside the box thinking. I recalled Darko and one AGer brought up this and I tried this (double deck). Both are great as decoupler for the bookshelf. Better than spring and rubber feet especially for bass response.

The want to spend money on an unknown product and one not commented on as a solution does present as being quite dismissive of the assistance on offer. 

Gaia Footers do work and so does the Townsend Podiums. I can vouch on these as my Loaned out AT 616 Feet used as Footers on Speakers assisted others in their making a decision about Isolating a Speaker.

I would say between the three footers referred to above, there will be very little differences detected in their effect on the end sound of a Speaker. Cost of the Footers will be the deciding factor if all three were assessed side by side.

There are very cost effective ways to experience a Pneumatic Footer, which will offer almost the same / the same effect as the above.

Make a Design for a Sub-Plinth using a Sand Box with a extended Skirt to conceal the items in the Link, which should be produced to a very pleasing aesthetic finish if done DIY for no more than $100 and this will compete with any $1000 suspension device on offer as a Sub-Plinth.

SVS SoundPath feet are almost as good as the IsoAcoustics and cost a lot less.  Spend the savings on acoustic panels.

if you can hear the difference, nothing should stop you from spending thousands on a piece of rubber

I've purchased some IsoAcoustics ISO-Puck minis. only cost $90. Bit of a cheap experiment.

Still wondering if maybe I should get some stainless steel Floor Protectors and Enhancers. They hold the spikes and protect the hardwood floor.

Lots of different input on this topic.... Making it even harder to decide.

So I got a chance to buy Quadspire QX7 Isolators. Half the price I see them for online. Not sure if they will do much.

These are just stainless steel feet that take in the plinth. Anyone know anything about these ? Am I still better of getting Gaia Isolators ?

You mention that they are bookshelf speakers: My suggestion would be to use Black Ravioli big pads and put at least 10lbs of bricks or something heavy on top of the speakers. You’ll need additional weight to tame cabinet vibrations

Stack Audio. https://stackaudio.co.uk/

The Townshend podiums would be the best to isolate, they isolate down to three hertz and they stop the vibration from going into the floor and back up into the speaker again, you can put them right underneath your speaker stands you just have to get the right size and the right size cells for the weight of your speaker and stand, they are far superior to ISO acoustic Gaia according to everyone that's tried them both, they said that the ISO acoustic Gaia's were very good but The Townshend podiums were on a whole different level better, I bought them and put them underneath my monitor audio platinum 200 ll and the difference was as if I had upgraded to more expensive electronics, most significant upgrade that I've done to my system.

I would recommend the isoacoustics pucks. They are relatively inexpensive and very versatile. 

I tried the Nobsound springs mentioned above...between mt MT cabinet and my bass cabinet...was very pleased with the sound....noticeably better than the Herbie pucks. I had before.

I have used Herbies products for many years and suggest: Tenderfeet to couple the speakers to the top of the stands and Cone/Spike Puckies under the spikes at the floor.

Ok sounds like the consensus is to just try them and try to hear a diff.

My speaker stands weigh 70lbs, speakers weigh 25lbs. But the speaker stands only have 3 feet not the normal 4 feet, so weight calculation is different. I feel like that might put me into the  Isoacoustics Gaia i category. Those are the most expensive of the lot. expensive trial and error.

Using the Gaia II’s on my KEF Reference One’s improved my soundstage. It is critical that the feet are on a smooth surface so they can grip it, or use their carpet spikes. It also requires that your speakers are very firmly attached to the stands so that the forces from the speakers can travel and be absorbed by the Gaia’s. Also note that the Gaia’s are directional and the logo on each foot has to face forward to get the full effect. And yes, you have to include the weight of the stands in your calculations. 

Isoacoustics Gaia made a big improvement in sound on my previous Kef Reference speakers. Everything more focused. And they look good too!

Live Vibe Audio brass decoupler sets. 

IsoAcoustics Iso pucks sound like a fine idea.  There are lower cost alternatives but they should accomplish what you're looking for.  Maybe find a place where you could return the pucks if you don't get the improvement that you're hoping for?  Then you have a free demo.

Herbies Audio Lab Threaded Stud Gliders to replace the spikes and dimes. Great on hardwood floors.

I use Nobsound springs between my Spendor SP2/2 and the top of stands (cheap and effective - opens up soundstage and increases detail and dimensionality) or these get solid reviews: Seismic Isolation Pods (not so cheap!)

@rick_n Or maybe IsoAcoustics Iso pucks ?

Yes, you would have to account for the weight of the stands for the Gaia feet.  You might get a better acoustic improvement by placing an iso stand between the speakers and the stands. 

Get a MiniDSP SHD and you can make your speakers do anything you want.
