Actually, I should point out Greg Timbers kindly offered me assistance some time back after emailing JBL for information regarding the tuning of the 2245 in the 4345 design.
The information Greg Timbers provided and answers to specific questions about the 4345 monitor were not only particularly helpful, but also of a friendly nature and resolved key technical challenges with the 4345 project which I would never have figured out otherwise.
