Dekay: Even a single driver has time delays as frequency is altered. If one wanted to "get picky" about it, the Manger and other "bending wave" type drivers are supposedly "more" time coherent across the band than other FR's. Mounting height of these types of drivers must be paid attention to though if one is to achieve the best / most linear results though.
Having said that, mounting height and arrival times become even more critical with "full range" drivers of more conventional design. Not only does radiation pattern come into play, but due to the amount of beaming of high frequencies taking place, arrival times will also vary as one sits further off axis. As such, one pretty much has to sit on axis with such a design IF one is worried about the time domain. Having done that, i found the tonal balance to be quite lean and forward i.e. not to my liking. Obviously, one looses bass as they bring the driver closer to ear level and these type of drivers are already lacking low frequency output to begin with.
As to the Jordan, i've seen limited testing on it. From what i can recall based on that information, it did more things wrong than right. As such, i lost interest in it rather quickly. I'm sure that others may be able to tweak better results out of the driver than what i saw, but "individualized specialty items" will almost always be built to address specific points while compromizing other aspects of operation.
As it is, i just threw the Manger out there as it seems to take a completely different approach. Whether it sounds good and is reliable is another story. It tries to deal with the various matters of sound reproduction in a rather unorthodox matter and does so as even-handedly as possible. As such, it may be a series of compromises that does nothing well. I'd be interested to hear from those that have heard or own Mangers.
El: Thanks for the info. I'll check it out when i get a chance. Sean
