Hi
I have measured both and use the B&C in a couple products at work which replaced the BMS coax driver (the originator of that design) .
The Celestion has a "good story", the B&C has en extended hf response and reaches 20K easily and the "off the shelf" crossover works much better than the BMS coax and stock crossover. These work well in CD horns which have a larger listening area, where the highs need to cover more seats. On a large enough horn, a high pass in the 300-500Hz range is easily accomplished. I use these where there isn't enough room for mid range cone horn drivers on Synergy horns.
The Celestion would be much more suited to a exponential (curved wall) style horns who's patterns get narrow up high, which can partially offsets the drivers acoustic power hf roll-off on axis and make a flatter on axis response albeit over a smaller area.
The pattern loss frequency can be estimated with Don Keele's thumb rule.
Pattern loss F=~ 10^6 / horn mouth angle / horn mouth width inches.
