The Bearded Woodwork
This is my first SubWoofer Box and I used 3/4 inch plywood because it's what I had on
hand. All of the videos I saw the people were using MDF (Medium Density Fiberboard) I
suppose it is because it's flat and inexpensive and makes for good surface for the application
of carpet. I chose to paint mine black because it's for me and I had black paint.
