Make Your Own
Homemade Bass Traps. If
you are handy with a hammer and saw and you are on a tight budget, here’s
a suggestion
for you. Build your own bass traps. Use 2X4s for the frame, ¼ inch
plywood for the back, and solid foam insulation glued to the plywood. If
you want to get really fancy, make the back detachable and build another
back, this one out of ½ inch plywood. This you will be able to trap
different frequencies when you are mixing down.
