I just learned that the original Gates Planetarium was trashed.
Anyone in Denver remember this?
Back in the late 70's the Planetarium was running JBL bass bins behind the perforated dome. Placed on the inside ring in front of the dome were 2440's on the Serpentine horns for the mids and 2405's for the highs.
I was told this system was later replaced with 4345's. I wonder whatever happened to the JBL 4345's that were in there. Now I guess they are using Meyer Sound gear in the new Planetarium.
