Diy sound insulation for isolating ceiling speaker back waves to floor above?

Hi all,

I’m about to install some speakers in the ceiling (surround speakers) and am wondering if placing pillows above the speakers will quiet down any effects of having ceiling speakers to the floor above? Kind of ghetto but I have the pillows here from my mini Marty builds as extras.

Any other known techniques for dealing with this?

the lower the FR the more energy there is to be transmitted

can you mount using an isolation / vibration absorbent material
that's only part of the problem

the denser the material , like 703
is that conducive to greater absorption?

what is the suspected xo for these speakers

is it TBD per Audy , etc.?

and the back of the speaker will radiate in a sphere, mol

pack that space ..

The only method that will have a noticeable effect is to enclose the speakers in a rigid box that is sealed to the ceiling drywall so no rear sound escapes into the ceiling cavity. The next level of sound isolation is achieved by mounting the box with isolation clips to the ceiling structure to minimize the transmission of box vibrations into the ceiling structure which then can be broadcast into the room above via flanking paths.

If you build enclosures for your speakers, remove the stuffing from the pillows and put it inside your speaker enclosures, otherwise, leave the pillows on the bed.

Thanks for the info. I ended up going ahead without them at the current time to see how much of an issue it even is before making an effort

Sounds like a great place for the mice to call home.
