Footers under big heavy speakers (Stillpoints Ultra 5, Sistrum rack, Finite Elements,..?)
Yes your experience with the Seismic Pods, de-coupled the speakers from the suspended floor. As does Herbie's Titanium Cone/Spike Decoupling Glider. When I isolate (de-couple) my massive Martin Logan Monoliths from my suspended floor, the bass becomes far tighter faster and deeper and without overhang, and the image is improved. If I couple them into the floor with spikes, then the bass becomes one note'ish the floor vibrates through your feet, and the image is also shot to hell. Cheers George |
Also adding my more recent experience with StillPoints under B&W 800 Diamond. The 800 Diamond is so heavy and stable that I initially left it with the steel ball rollers on the carpet (suspended chipboard floor). I then replaced the rollers with StillPoints Ultra Fives which improved mid-range quality and micro-dynamics. No significant change to bass quality. Unlike the 803 Diamond, I didn’t need to use a platform with spikes for stability due to the huge 800 speaker base! Again my experience is that optimal positioning of the speakers is more important than any isolation. |
Good work knghifi, these Titanium Cone/Spike Decoupling Glider will be the way to go if you have a suspended floor and you still want to use your speaker spikes. Some very good feedback from purchasers with suspended floors.http://herbiesaudiolab.net/csglider.htm I changed my order to Giant Titanium Cone/Spike Decoupling Glider. Should arrive this week, My 23'x33'x15' family room is all hardwood floor on top of garage. I don't have booming issues or one note bass with current speaker but curious if decoupling will yield any improvements As from what I can see the Stillpoints wouldn’t be right for a suspended floor as they don’t decouple from it at all, they actually couple, and nowhere on their site do they even get into decoupling for suspended floors.I thought Stillpoints do decouple in TAS RH review? |
I thought Stillpoints do decouple in TAS RH review? Unless there’s a hidden "rubberized isolation" section within the two sections of the Stillpoint. There is something between the two sections, but I was told this is just ball bearings, if so they wouldn’t de-couple from the floor. As to de-couple you need something soft between the two sections that won’t transmit into the floor. http://www.analogueseduction.net/user/ASTILLULTRA5ksjdhfgf.jpg Think of engine mounts on a car, they are nearly all made with rubber de-coupling from the chassis, some esoteric ones are de-coupled using fluid. Any hard mount would make for a very uncomfortable ride. Cheers George |
Ball bearings can provide isolation, especially in the rotational directions, just like other roller bearing or ball and socket type isolation devices such as Dharumas and even steel springs which are not rubber type material now that I think about it. It would depend on how the ball bearings are implemented in the design as to whether they were an isolating element. |
