Discovered something I had forgotten.
The tweeters in these baffles are BG Neo3-PDR's not the GR versions. The pair of GR versions went to a person wanting to build another GR speaker system that needed those.
Weather looks good so will try another round of measurements today. Found out the connection terminals on the Neo3-PDR were to close to the rivets and shorting out. Dropped the tweeter level way down, so now insulation is on the rivets to stop that from happening.
Just got the msg that the second Parasound Halo A23 amp arrives today to power the Monolith planar system.
