, you wrote about how the hoverboard suspension provides significanly more displacement and “the shaker force of each JBL is multiplied exponentially.”
You sort of replied to my concerns earlier, but I’d like to make sure that the hoverboard approach is doable in my case.
My intented platform (approx. 4’ x 8’ with 4 x JBL GT15-12) is supposed to end up in a large, open layout type room, on the second floor, as close as possible to three (in this case),
weightbearing walls. I am slightly worried however about the long term effects of these vibrations on the structures below me
, and that isolation here, might be more critical than
if I’d been able to just put the platform on the ground floor. But this is not possible for now. Maybe I’m worrying for nothing. But still, it will be a dynamic
load of approx. 336 lbs,
vibrating at single/double digit Hz, for a few hours a week or so.
Should I just try to increase the dampening for this platform further, or forget about the hoverboard approach in this situation altogether?
Looking at the Hudson 2.5” iso specs, it says “Ideal for 50- 100lb components”. Eight or so of these should be more than enough for this weight and platform size.
The room I’m in has wooden flooring. I can maybe first lay down some rubber tiles or mat on top of that. Will increasing isolation beyond that still have an effect?
I’m thinking about putting these between the rubber floor mat and the 2.5” isolators+tubes: https://www.diversitech.com/en-US/item/id/2445
Something like this maybe:
