My attic has blown insulation.
I moved the insulation around the areas I put the speakers.
Speakers are installed and sound great.

I want to put insulation back around the speakers, not for sound, but to help with cold air and such. I dont want to push the blown insulation back due to it getting into the speaker or causing a fire somehow.

What is the best way to go about this? Can I just lay a piece of pink fiberglass insulation over it, or cut a hole in a piece and lay it over it?
I am not sure how to do this because I do not know if laying insulation around the speaker or on top of it poses a risk of getting hot and causing a fire.

I know it sounds strange, but I had one CI tell me that they have used the styrofoam tomato cages as a backer to the speakers in certain situations. I thought it sounded kind of strange, but I guess it would provide an enclosure and keep insulation out.

Heat is not an issue, but obviously you don't want insulation getting jammed in there. If you want to do it on the cheap, I would use regular fiberglass bat insulation. Get some that is at least as thick as the speaker is deep. Take one piece cut a hole & place it around the speaker. Take a second piece & place it over the first. Put blown-in insulation around/on top of that.

These Pro Wire Insu-Flate ceiling speaker protectors are cheap from PartsExpress and should do the job. Since you have attic access, a shower-cap would work as well.

Reviving this old thread. I have the monoprice 4104 that I have blown in insulation resting over top. I assumed it would be designed for this but now am a bit worried. Is there any difference to using the parts express ones over shower caps? I dont want to cheap out but if a shower cap will do just fine, Ill that route. Any thoughts?

I have used these in the past. Inexpensive and easy to punch a wire hole through.

Just clear the insulation away. It's not going to hurt it.

I used a plastic pale from home depot, I stuffed inside with polyfill, then a thick bead of caulking on edge & set it over cut out..it worked great & less than $20. Even improved sound. Just get big enough to go outside a 1"-2" space to clear mounting tabs,you be fine.

Well Im having R60 blown into the ceiling (crazy I know), and I wanted to not leave any gaps. I will get some shower caps or styrofoam coolers if that is all that is needed, just didnt know if I needed 40 dollars worth of parts express specially designed speaker bags....

I was thinking of getting some 9x9x9 cardboard boxes from Fedex and using those to block the insulation, any reason why this wouldnt work?
