Ultra 5 - The Ultra 5 derives its name from having five pockets of Stillpoints
patented technology. When using four Ultra 5's under one component or
loudspeaker, 20 pockets of technology are being used. A 1/4-20 female
thread is located on top of the flat half of the Ultra 5. Stillpoints has added
a 1/2-20 female thread to the beveled half. This allows for the attachment
of the new Ultra 5 "Bullet Spike", or an adapter specifically made for
attaching the Ultra Base.
