I've had this box for almost 2 years now. My prob is that I've put so many speakers into this box that there are screw-holes everywhere. What would be some ways to fill the holes in this box? btw it don't have to be exactly perfect for its only for a mtx 6000 series.
Just add another 3/4" piece of mdf to the front of it and cut the new holes to match the new speakers. Make sure you glue and screw it on tight so it doesnt rattle.
