I am currently replacing some old speakercrafts CRSONES I have in my basement. I am replacing with a Dayton ME820C. When I installed the speakercrafts I stuffed some fiber glass around them. I was wondering if anyone has tried getting anything else or has some sugestions. I will be installing 8 total. I have 9 inches of room between the ceiling and floor upstairs. The speaker is only 4 3/8 thick.
