Only a handful of speakers made today come close to being physically "time coincident" (defined as having all drivers in the same polarity with individual driver responses arriving at the ears at the same time, sometimes called "time/phase coherent"). AFAIK: Thiel, Tannoy, Green Mountain Audio, Dunlavy, Vandersteen, Quad, and a few others are the only ones that employ what might be considered as, or something close to being "time coincident". Do you own or wish to own a set of speakers from one of those distinguished brands?NOTE: Some would argue that it is not necessary for a multi-way speaker to have all drivers in identical polarity IN ORDER FOR ALL DRIVERS TO BE PERCEIVED AS BEING TIME COINCIDENT. But please, lets try to forget about that argument for now. If it is possible for you to ignore that argument, I would be very interested in finding out how many of you own (or would prefer to own) speakers from manufacturers like those listed above.
Some of you might own or prefer speakers that are not truly "time coincident" because they display unique characteristics that appeal to you more. Maybe you feel that other aspects of speaker performance (dynamics, dispersion characteristics, timbral accuracy, etc...) seem to become compromised in the quest for "perfect driver polarity". So, feel free to explain why you might choose to ignore "coincident" designs in favor of another type of design.
