If people, research the best isolation products, they combine metal and rubber-based solutions. Springs are also a well-used method. I could not find an off-the-shelf solution that offered everything we needed for the range of bass frequencies Simhub may output.
I am not an expert on this or a qualified engineer...
To be fair to some others we have here, that appear to be experts in advice on this topic. Yet they do not base what they offer, on physical tests. Nor do they elaborate on how/why their advice will operate with the wide range of frequencies that Simhub may generate and which is also very dependent on the level of hardware being used with it.
From my own perspective, I can only share and help bring a product/solution that was developed over time which worked very well on my own build and bettered all other isolator solutions I purchased and tried. Testing was done with over 12 make/models of transducers, so basically covering the very best to the common entry-level, users' potential installations.
I learned a lot from doing just that, trial and error, and applying some creativity regards discovering a solution to be simple to install and affordable.
The springs shown in this example can withstand well over 150KG each. They are stiffer than used on some high-end pedal solutions. If we use a softer spring it is more likely to dip, so it was finding a balance that kept the height minimal, was strong enough, and could be easily adjusted by the user.
Background Development
I will show this simply to give some perspective, below are some previously shared images of my own efforts with my own build...
My own custom rig, it comprises of two L/R independent structural and isolated sections. I re-built an entirely new base at the start of this year. It is extremely heavy/solid. The reason for this having independently isolated sides, was to maintain as best possible the "stereo tactile" and limit crosstalk between the left/right positional effects, retaining it to the correct channels as the telemetry generates it.
Here we see the middle pair of independent sides. Yet they are missing the top section plates my seat/pedal support frame will be attached to. Notice that even after all the isolation materials including top/bottom 8mm plates the vibes have to pass through. I also minimised as best possible, their physical connection into the horizontal support frame underneath.
These have only 4x bolts for each isolation tower. Yet even with all these materials, vibes can still transfer down through one side, over the horizontal support and up through all the isolation again on the other to be felt (@25% energy) on the opposite side.
On my build, each side has grouped pairs of springs on isolation towers. So 6 springs each side (2x pedals 2x mid, 2x rear) for the length of the cockpit. With one side using these same springs as shown and the other using a slightly softer option. The stiffer option seemed better than using the softer option and tightening it more.
The RACEBASS solution bettered this $200 worth of multi-isolator combo.
How it all began, early testing with the springs.
As I say, I am not an expert, what can be said is, based on actual tests with transducers and Simhub. These are the better, performing solution that worked overall the best than other solutions I tried. Note that some solutions I tried costing 3x more per unit than what these will cost.
People often wonder what keeps me with my own build. They do not realize I am seeking to build as part of a hobby project, a rig specially made for the best tactile immersion. Simply because my own build will go to crazy lengths regards the tactile it incorporates. So there is a difference in adding tactile to a cockpit and seeking to find ways to build a cockpit, specifically targetted at achieving something with tactile that no other build yet has.
Not as to boast but to give an idea, I have spent over £1500 on isolation testing/development for my own build. This is a key element for my own rig and an important one. It will likely offer isolation well beyond what many builds have but even with this, it is impossible with ultra-low subsonic frequencies (with multiple large BK) to fully control crosstalk.
So part of my own costly experimentation/findings over the last 18 months, regards stereo tactile, or in seeking to build the best "corners" based installation possible. Well, it has been a bit diminished, even with my best efforts not being able to eradicate stereo crosstalk.
My findings are, that accurate positional/placement for effects is not as important as the "quality and range in the felt sensation" of the effect being generated. Yet we still can use multiple transducer combos to expand the number of effects we can enjoy and these offer much greater performance than the typical approaches with tactile currently bring.
