I tend to like Brit monitors...such as Spendors,Proacs, and my Quad 12Ls...and all of these companies are rather "secretive" on disclosing exact crossover componets,design schematics,etc...in short...they dont overly advertise being time/phase correct...but Im sure they incorporate some of these traits....in short...I feel "phase coherent" has become a marketing slogan...and really detracts from the few companies who are actively applying this viewpoint...and even after listening to Vandersteen, Meadowlark,etc...I still opted for the imaging precision,transparency,soundstaging,and larger sweet spot of a full range monitor...the "lobing" effect of 1st order designs...in my humble opinion...far outweighs the benefits...
