Are you ok with others posting in your theater thread like this or would you prefer I take it to a different build thread?
Hey Steve...no problems with the posts at all.....the more we can share here, the more everyone else can benefit and come up with their own designs.
If those door bumpers are anything like the ones I link below, they will likely be way too stiff. I tried the ones in the Amazon link below and the TR response wasn't very good at all....those were the poorest performers when I was measuring with the VS. Maybe your 15's, with the extra mass will be enough to overcome the stiffness, but I've found through my experiments, you want the platform to be as "floaty" as possible for the BOSS to feel natural and not "gimmicky"
The 2 biggest factors that influenced this "realism" was the stiffness of the platform and the softness of the rubber. For the plywood, 3/4" plywood is minimum, 5/8" didn't work as well and 1/2" wasn't good at all....too flimsy and required too many supports which basically coupled it back to the ground too much. The softness of the rubber is key.....you basically want that entire monolithic platform to respond on demand from the drivers as much as possible. To get this response, the isolators are key.....the softer, the better.....as always, there's a balance though. If they're too soft, then the platform won't support the weight when everyone gets on it.
The ones I linked to in post 29 were the best at delivering this realism when coupled with a rigid platform.
To give you an idea how "floaty" the platform should be, check out the video I link to below for a recent BOSS completion by AVS member
Amazon isolators/bumpers that didn't work very good:
Link to video showing how a properly constructed BOSS platform will float.....check out post 58 where
shows how his BOSS "floats"....this is using the prescribed Amazon isolators I linked to in post 29 in this thread.
