To dial the Phillips Design OH-16 omnidirectional loudspeakers correctly would require some help. It was a few days before my fellow audiophile friend was available. This was the first of several "scoot and listen" sessions. After the third session, we had it dialed in as well as we could. The final placement had the speakers about three feet off the side walls and about two feet off my front wall. Very close to the diffusers. Much closer than any speakers had been before.
