Been a while since on the site. Thought would share this iPhone Passive Speaker. Looked around the net and found different ways these have been made and made up my own pattern. Used Forstner bits to do the holes progressively smaller and deeper. Made of 3 pieces of wood, 2 pieces 3/4" Walnut and 1 piece not sure of the specific wood, some type of exotic that I had purchased a while back. Middle piece of walnut has the groove in it for the sound to travel out to the holes. Brass screws in the corners are more decoration now than when assembling. Added the "H" (1/16" Slolid Brass) and .040 Copper to it for decoration and stability on the bottom. Going to give as present at work for secret Santa gift.
