Based I what could see on their website T&P coherency does not appear to be part of the design principle the way it is for speakers like VS, Thiel, and the old Meadowlark brand. These have a particular sound that comes from those 1st order crossovers and time aligment that may be what appeals to folks that like these speakers. Heard very good thing about the Devores, but it appears to take a different approach.
