      Way back in 1979 I was building a set of speakers that everyone seemed to like. They were made with Phillips Deforest drivers (no longer available) with a 12″ woofer, 2 x 4″ mids and 2 x 1″ tweets. I won’t say the sound is bragable by today’s standards but they did well enough.

      But in that design I did something a little different. I used a multi-layer cabinet design consisting of a layer of 3/4″ MDF board sandwiched with 1/2″ plywood (on the outside) and isolated by a thin layer of silicone calking compound. The result was a virtually dead cabinet. No physical vibration at all.

      More recently I came across this video … https://youtu.be/EEh01PX-q9I … that revisits the idea. (jump to 24:30 for the cabinet discussion)

      Now I’m wondering if others have experimented with similar construction techniques and what the results were.

      This is a great topic.  I can’t wait to hear what others have done.  I have done this with Hardwood.  If it is especially large or resonant, I will use an MDF backing to help deaden the sound.  I know there are quite a few people who swear that if you do these multi layers that you should use green glue for it’s noise suppression traits.

      I personally have not used green glue.  I’ll be interested to see if anyone else has.

      The idea was to have a box in a box with a vibration damping layer between. The video I linked to explains it perfectly and probably in more detail than I could.  

      Sometimes I really miss those speakers… they could rattle the dishes in the kitchen any old time 🤨 but I lost them in a house fire in 1983… such is life.
