i need advice regarding the ercommended acoustic foam lining: 1) what size of egg carton shaped foam is recommended (peaks vs valleys); and 2) what density of foam is ercommended for best results...thank you for any replies...dko

I have used with great success a foam mattress topper- it seems to have a good density and it's the 1 1/2" size that everyone recommends. Here in T.O. you can get two of these for about 30 bucks - the ones I got were for a queen size mattress. Hope that helps.
