Can this vibration isolator Iso Puck Mini support my ATC SCM 11?

I've read somewhere but don't remember where now, but the recommendation was to allow at least a 10% difference in weight of speaker/tolerance limit of pucks or other IsoAcoutic products such as the Gaia's and Oreo's. Speaker weighing 30lb would need at least 33lb of tolerance from IsoAcoutic support/isolation products.

Hope this makes sense/helps 👍

@painter24 thanks for your reply.  I thought another way round that it should able to support extra 10% tolerance in weight.  

Yes, every design should have some safety factor. I have continuously seen people use mini to support 12" sub that weighs about 26 lb +-. The critical part is you DO NOT place the tip of the original speaker feet directly onto the puck mini primarily because the point pressure may well exceed the loading allowance of the puck. Use the perimeter to support the weight uniformly and it should not impose issue.

I think a more critical part is whether puck mini is effective as an isolator / decoupler. Based on what I have read, people found it is effective to isolate the bass energy and improve on transparency, details, image, etc. However, it tends to drive the speakers’ tonal balance toward warmer side but YMMV. If you found the similar and dislike it, you might want to experiment with an fairly inexpensive but effective decoupler called drum dampening pads. I used it under my speakers (Burchardt S400 mk ii) which has a similar weight to ATC SCM 11 and save myself $99. They help stablize the speakers on the top of the stands as well.

Hi @lanx0003 thanks for your sharing and reply. I received my puck mini yesterday and placed them over the edge (perimeter) of speaker stand to maximize the spread out of speaker load with uniformity.

 After some auditioning, It is obvious the soundstage has changed, more refine and detail mid and treble with clarity tones, but I find the bass too has been reduced, some tracks are acceptable but some may not to be my liking. 

I would listen to more genres especially jazz, classical if I will let puck mini stay below speaker or I would transfer these isolation feet to support my preamp (8kg) and streamer (3.5kg).

Op,

When I experiment with spring isolator (by Nobsound), I found the bass is reduced too so I returned them. Rubber feet / drum pads actually perform much better in that regard. Noted that rubber feet will still transfer some bass energy to the stands so they are not an ideal decoupler. But, with gel pads, you felt almost nothing on the stands. I actually stack up two gels to support each corner of the speaker and they do not compromise the bass weight. It is hard to explain the physical rationale behind it... Darko briefly mentioned about them in his channel so I went with it and no regret ever since...

It is also interesting that you found the SS has changed. In what way? Wider, deeper, taller?

@lanx0003 

Interesting, I used to half cut squash ball as isolation pad for my previous bookshelf speaker AE Evo One many years ago... I may try again one day.

On the sound change, the depth/width remain unchanged, the clarity of mid to treble frequencies (vocal) are clearer and refine, most likely as the bass has been reduced.   

And I have been auditioning for the past few days, and slowly adapt to the "burn-in" brain , most of the tracks/songs are good with Puck Mini.
