coolio. one option is to install a couple or three 1x boards running perpendicular to the joists (paint to match the ceiling) and attach there as if will provide more flexibility in placement. you can use toggle bolts through the board and ceiling to ensure enough strength.

rings would be fine. glad that there is minimal vibration as-is.

the isopod would certainly (well almost certainly) provide isolation at the higher frequency unless they're specifically matched to the speakers - the whole point in the isolation is to get the natural resonance down to about 1/3rd of the lowest frequency of the speaker. so if the low end is say 39h...

yep

the main issue isn't venting, and most times the passive air flow will suffice, it's the open port on the back of the speaker - being buried in the soffit, or plugged will change the overall speaker response - which may be better if plugged. another is remove the electronics and create a backing pan...

not sure what your level of acoustics treatment is besides the mattress, but if temporary, then more wall and ceiling mounted absorbers which are little more than picture hooks or some small brackets to mount. overall the response is consistent across the spectrum so whatever the settings are they a...

a full size mattress which is filled (not simply springs) can absorb quite a lot of LF energy. overall - with the sub - the response is decent +/- 8db with 1/3 smoothing and if you don't have the first reflection points covered top and sides, then you'll want to add those. the desk (the 1.5ms reflec...

looking good. remember though, too much yanking can impact your eyesight

the MLV could be useful for the mass as well as some damping of the cabinets forming the duct. in general, parallel runs of high freq protocols with electrical an add noise to the electrical. so spacing at least a 750mm apart from the electrical - although running those low power cables together sho...

you should be ok from a sag perspective. the thinking should be the silencer assembly can be secured to the wall as part of the isolation boundary. where you might have it not in full contact would be either the ceiling or the wall, but not necessary both unless you already have that joined hard. me...

this:

no worries. just a note from when i do designs, even with inside out ceiling, is take advantage of ledgers to conform the positioning of stuff i need to lock into place and want them installed as a single unit. using metal straps to secure them all around. then i typically add the large(r) soffits f...

along those lines: decouple pipes, wires, ducts, etc. electrical - use bends and loops to avoid tight wire connections across isolation boundaries, use decoupled conduits when spanning isolation boundaries. use flex duct or duct decoupler to span isolation boundaries, vacuum up the crud from constru...

you could probably just use 1/4" -- not sure why i was thinking 3/4"

possibly late here - however - presuming you'll have a soffit around the ceiling for additional absorption, lighting, wiring trays or conduits, etc etc, using a ledger board under the edge of the assembly can assist in positioning and retaining. same way you'd do a cabinet where you ultimately will ...
