Townshend Springs under Speakers

Did you think this was ASR?

OK… What is ASR?
Do you recommend it?

Apart from 3rd hand reports from Richard Vandersteen (albeit weighty opinion in relation to use with Vandersteen speakers),

So what makes his speakers less responsive to springs?

it does seem to me that the naysayers are made up of people with no experience of the Townshend products - some with another axe to grind.

I am not a total naysayer, I just want to know how they work… and whether they would work with my speakers. (Before I spend the money.)
And academically… what makes them work with some speakers and not others seems pretty interesting.
My speakers are currently on a concrete slab, but will be soon moving to another house on a hardwood floor (on joists).
They have been on spikes for 15+ years (on the concrete slab).

I could picture having a slab of granite on springs, and the speakers on spikes on the granite. This assumes that the new floor might be worbling the speaker.

There is no axe.

Audio Science Review. A forum where only measurements are considered and subjective opinion is pretty much ridiculed and shouted down.
Personally I think it is useful for the measurements - some of which I've found to corroborate my subjective opinion of components I've owned and got rid of (years before), but subjective assessment doesn't count on that forum.

Don't know. Given the wide range of speakers that have had positive endorsements, if it doesn't work with Vandersteen speakers they would seem to be an outlier. 
The other question is whether Richard tried the Podiums on a range of his speakers or just one of his top models which had been highly optimised for another approach?

That's wise. I've experimented with other (cheaper) isolation options and found them more effective than spiking for my equipment/room. That, along with people using the Podiums with same brand/type of speaker to excellent effect, gave me sufficient confidence to bite the bullet.
I'd advise to read/research as much as you can and attend a demo if possible (wasn't for me).

@audiopoint, Yes, we are now in the Nashville area and loving it.  Also, The Audiophile’s Wife is seriously considering writing again.  If fact, we are contemplating a shared site where we sell audio cables and she hosts her blog as well as other fun antics. 
I did have some Apprentice platrforms in my rig here for a season.  The speakers I used them under were the Acoustic Zen  Crescendo and my current Dali speakers which I have had for some 4-5 years now.  
Always liked the sound of your products and that Energy Room you built for Andrew is a listening experience I will never forget. Never! Just a sensory delight. Even the sound of my own voice was startling in that room. 

I do know that using springs on suspended wood floor construction works and I did the experiments.  My thought is that the floor was picking up the vibrations from the speakers and transferring the vibrations throughout the structure.  This caused bloated bass and smearing of the music. 

Those that have concrete floors would need to weigh in on their experience before and after springs. 

Just to throw my two cents in...

In addition to altering the number of springs and the position you put them in your Nobsound units, another thing you can try is getting 5/8 heat shrink tubing (non glue inside type) and cut it at the length of the spring then heat. Just enough spring will be exposed at the ends once shrunk to put them in the bases. This will dampen the springs action. Try doing some or all of them.
