It's coming time to hang my Sony VPL-VW1000ES in my theater, and I'm wondering about vibration isolation. As described in my build thread, I have a total of seven subwoofers in the room, of which three are actually mounted in the ceiling. It seems possible that all this bass energy could vibrate the ceiling enough to make the projected image move visibly.
As well, while I don't expect foot traffic in the room above during movies, it is a high-traffic room generally. So, it seems prudent to protect the projector from day-to-day vibration caused by foot traffic, even when it's off.
We will be doing a vibration test in the room this coming month, but I figured that it was probably a good idea to just go ahead and plan on a mount that has some isolation, so we don't end up having to drop the projector and replace pieces if it turns out that we get visible shake.
Looking around online, I see that Da-Lite, Chief and Peerless all offer various types of vibration isolation. Da-Lite's is a simple arrangement with rubber isolators built into the bracket that mounts to their UPM-1 universal mount. Chief's is an elaborate system of masses on long arms, but its weight limits are insufficient for the 1000ES. Peerless seems to have the vibration isolation in the piece that actually installs to the ceiling joists.
Anyhow, I'm wondering if anybody has any experience with one or more of these products, or with other solutions, and can comment on their effectiveness.
