Speaker Isolation feet,- worth looking at, or nonsense?

If the things on top can't vibrate or move... just be sure to put some mousepad or similar in between.
 
I would appreciate informed views on speaker isolation feet as I am considering examining this. I have a pair of B & W 802D speakers weighing 80kg each. I currently use them with their factory fitted wheels. Rest of the system is Cary DMS 700 streamer, Music First Baby Ref V2 passive preamp and 2 x Pass Labs XA 60.8 class A monoblocs. Yes, usual speaker cable, Shunyata Venom X and AVID SCT XLR connectors

The floor is Travertine tiles on concrete. I am considering Isoacoustics Gaia 1 Neo feet. I have quite a number of friends and acquaintances who say they have had a really noticeable effect on the soundstage.

Would appreciate informed opinions on the matter
There are tons of threads here on ASR, with measurements. Soft feet can be beneficial if you have resonant surfaces, benches, desks where your speakers sits. But you do not need more than e.g. sylomer feet to prevent vibrations through.

 
I like what Ascilab does. Their C6B bookshelves come with a sheet of ~1mm dense neoprene on bottom. Not as good disconnecting than some rubber feet, but does the job OK. And it looks like there is nothing, boxes can still move around, no scratches..

I would maybe look for 2-2.5mm thickness. Had neoprene like that as thick mousepads. And use that instead of glue-on rubber feet.
 
Speakers.

As I stated, for "basstands", when placing a speaker on top of a sub.
Just get some rubber adhesive feet. You may already have some in a drawer somewhere. Or go get some at the dollar store.
They work OK for keeping furniture from moving around. Will do the same for speakers.

None of these are going to change the sound in a significantly audible way. So to the OP's question: the sound benefits are nonsense.
 
Does the same go for spikes on floor protection disks on a wood floor? Are they of value? Could I just use easier to manage rubber feet?
I replaced the spikes (and screw inserts) in my Rega speakers with some spare feet and inserts from Ikea Besta units and some suitable diameter foam pads. It's much easier to position the speakers now (and re-position after the cleaner has been!).

Sylomer is better than rubber or sorbothane. I’ve had mine for 30 years, no degradation.
 
For wooden/tile floor I can also recommend self-adhesive felt pads.

One might be too slim, but I have some really heavy floorstanders with 2 x 1.5mm pads. Top one matches the speaker metal stand (black), bottom one better matches the floor tiles (brownish). They decouple just like everything else, no scratches, easy to move the speakers..

Same thing for subwoofers. The large X-Protektor do a very good job for my SVS boxes.

 
Possibly slightly off topic, but connected to the issue of loudspeaker cabinet vibrations or their absence. Its often assumed that placing plant pots etc on top of speakers degrades the sound. I have never been able to discern any difference, but I’ve never done a blinded comparison and don’t see how one could (shut you eyes while assistant shuffles plants around?)
The ability to act as glorified plant stands has secured the acquiescence of my partner to the presence of a lot more loudspeakers than I’d otherwise get away with.
A very long time ago, back when TVs had CRTs, I had a couple plants sitting on a TV (it was a tiny apartment). My wife decided to water the plants one day and overdid it a bit. The water ended up inside the TV and destroyed it. I would not advise using speakers as plant stands for similar reasons.

I use these things under all sorts of household items that sit on shelves, including some small speakers. They seem to be very soft silicone, with one side sticky and the other not. They keep things from sliding off shelves and would probably reduce vibrational coupling between things. I've been using them for a couple years and notice no degradation of the material and no damage to surfaces in contact with either side.
