If I were a guessing man (and I am) I'd guess that Geddes speakers would sound better , but Keele's more impressive. Geddes does use better drivers and a concept that is long proven.
As bear says, use darn good drivers. Audience does in their line array. Of course one advantage of all those drivers is that they don't have to work hard, each one so each driver is not so strained. I think that if Don Keele had move his crossover point up a notch, it would have been a lot cleaner. The heavy carpet was limiting the bass from the array.
But Earl has a point. Horizontal beamwidth was not constant from top to bottom of the array. It gets tighter toward the top. But within any given horizontal slice, it seems constant. I don't know of any speaker that has a constant horizontal beamwidth from floor to ceiling.
