Thanks, Jon.Oh, and about design I'd add that it's philosophy has as much or more to do with sonic signature than anything else, at least outside major parameters like bass extension and available power. Design is the intangible factor but determines nearly the entire personality of the speaker system. It's not uncommon to find so-called house sound shared across models, and in some cases, even brands. Individual drivers each have their sound but their system's personality is at least as important.
Do you have any shortcuts for evaluating the sound of a driver, other than building it up in an enclosure to hear?
And would you have expected more difference in sound between the dipole midrange (Motion 12) vs the direct-radiating midrange (A5)?
