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.
Footers under big heavy speakers (Stillpoints Ultra 5, Sistrum rack, Finite Elements,..?)
Revisiting isolation and coupling for my main system, I wonder if I would try better coupling devices than the large Symposium Svelte shelves (19"x24") I currently have under my Duntech Sovereign 2001s
with 21" w x 35" d wooden base, weighing 360lbs each, which in turn rests directly onto wooden floor. My room was pretty lively before the isolation/coupling and I need better coupling/draining of energy for the speakers.
What would you suggest?
I could try four Stillpoints Ultra 5 with base under each speaker or what I hope to be at least equally good and more economically is a pair of Sistrum rack platform (using AudioPoints 1.5) that measures 22.75"x 26.75" (I don't think their standard speaker stands can provide enough balance). I could buy a Sistrum SP-4 rack and use two platforms for my speakers. This would be budget wise the same if I would buy two Apprentice SP-SA-XL-4-1.5 (18"x24") as I am looking for a new rack for my second system (Home Theater).
Star Sound seems to be a very reputable company but earns less coverage than, e.g. Stillpoints.
The third and probably least talked about solution would be Finite Elements Cerabase but I find less buzz here on the Gon.

Ball bearings would transmit like a solid metal engine mount on a car, not isolate. Remember back to school Newtons cradle??? https://en.wikipedia.org/wiki/Newton%27s_cradle#/media/File:Newtons_cradle_animation_book_2.gif Cheers George |
