Ceiling Speakers - Vibration Dampening
Hey, I am installing ceiling speakers in my house on the first floor. The front speakers will be directly below my son's room (he is 2). I have done some research on speaker boxes, etc. to reduce the vibrations, but everyting seems to be made for new home systems. I don't want to cut anymore ceiling than necessary.
Here is my idea. Can I stuff some pillows (foam) between the speakers and the 2nd story floor? There is about 8 inches of room. Will this reduce the sound and vibration felt/heard on the 2nd story? Is this a fire hazard?
Thanks for your help.
