Robber feet. Good one.
Townshend will put a spring in your step. Heh.

Townsend springy platforms for my Sasha 2s, springs not ISOA GIAS, HRTs for electronics???
I noticed a lot of discussion recently about springs as OPPOSED to spikes, Iso acoustic GIAS or HRT supports. I may be way late to the party, but in tracking this down I discovered the company Townsend. The engineering may be complex but the working concepts are pretty easy to grasp, but do they work? The company's suggestion was to remove my GIAS under my Sasha 2s and additionally add three platforms for my electronics, two under my ARC REF10 and one for my dCS Bartok. A 5K tweak is a lot but not out of the question. After all when a pair of Cardas interconnects is $4250, 4 to 5K for proper support for five components does not sound unreasonable if they make a significant contribution. Does anyone have experience in what I might expect these products will contribute? The pitch is to buy it all to get the best price, but is there a progressive implementation that makes sense? The company rep suggests replace the GIAS first, then source, preamp then amps. I can't wait to hear from the collective as while spring suspensions have been around forever on turntables, the trend I was aware of has been toward ridged coupling for speakers. Even my old Krell KSA had factory spikes for the footers. Old dogs CAN learn new tricks if it sounds better!

Interesting question. They work great on my wood floor, a lot better than anything else I've tried. And there are guys with concrete and tile and hardwood etc. This is one of the demos that put me over the edge, Max stamps his foot from 15 feet away, you can see the spike speaker ringing while the Podium speaker is dead silent. https://www.youtube.com/watch?v=BOPXJDdwtk4 That is one of those convention center solid concrete slab floors. Concrete transmits vibrations just fine. I knew this from growing up living in a basement, but still it is cool to see. In spite of being isolating springs and all it does still seem to matter what they are placed on. Another guy on carpet said he tried a slab (wood or granite, I forget) under his and it improved detail even more. So I tried BDR Round Things under mine and sure enough, it was good before but even better with! No surprise I guess. None of this stuff is magic. It all works together. However good something is, it can always be tweaked and made just that little bit better. |

Right. That's what did it for me. For a long time the prevailing wisdom has been to pretend that cones and spikes act like diodes that pass vibrations one way only. This never made much sense but it did seem to work. Then Max came along and showed that not only do the vibrations go both ways, they come right back up through the floor into the speaker and cause the speaker to vibrate enough to smear transients and blur imaging and other fine detail. It would seem that by allowing the speaker to move freely there will be a loss of dynamics. Because f=ma. But the mass of the speaker cabinet is so much greater than the moving mass of the cones this is negligible. What is not negligible is the ringing that is eliminated with springs. This is clearly demonstrated with the iPad seismograph. What is harder to demonstrate, but easy to hear, is the improvement in detail and dynamics. Because dynamics are not just the absolute volume we hear, it is also the dynamic range from the quietest to the loudest that we hear. So while Podiums probably do take some tiny smidgen of volume off the top, they lower the noise floor so much that it creates the feeling of more dynamics not less. This at any rate seems to be what I hear and noticed right away when using them. I know why I noticed too. It was because I was expecting less dynamics not more, and was surprised when it felt like more not less. Then I realized the reason: the ringing was gone! |
