Ceiling Speakers In Attic

From what i see and if i understand what i see it.
Ceiling speakers in attic. 4 5 out of 5 stars 258. You can do a quick and easy install with a lot of insulation contact that may muffle higher pitches but preserve a good bass response. In ceiling speakers can come in contact with insulation because the insulation is fireproof by design. Above the room is the attic to which i have access.
They will fit a much larger speaker than my 9 speakers so they are rather universal. These worked well enough to protect the in ceiling speakers that we installed in our media room. Planning on installing 4 in ceiling speakers for an atmos setup. From what i see and if i understand what i see it seems to have some batt insulation pink fiberglass batts maybe.
Above the room is the attic to which i have access. Add a couple of boards between the main rafters one one each side of the speaker and fill the box created by the rafters and added board with poly or fiberglass insulation. However there may be impacts on the sound quality of the speaker depending on how much contact there is. Like others i ended up sealing not ceiling these to the sheetrock with silicon sealer to keep the insulation dust debris out.
