Drubin & Dodgealum,
While I would consider you cynicism about speaker design with multiple options using the same drivers regularily in different boxes and with (or without?) crossover adjustments, very reasonable, consider that many of the major manufacturers put out multiple models with different drivers, different boxes, and different crossovers, and is continually introducing Mk I, II, and III versions, and then moving on to a new model. One must wonder about their level of expertise and dedication to producting a speaker that is truly a value. Names intentionally omitted but they are well known and have large followings. Same also applies to components as well.
I'm much more impressed by the small manufacturers (I would think Harbeth would be one) who take the time to get a good basic design in the first place and stick with it, only making changes allowing for slow evolution or the needs of the end user.
Personally, I think far too much "emphasis" placed on anything (other than quality component parts) is likely to be marketing hype. Especially when it comes to design philosophy and esoteric or new stuff.
IMHO there is nothing inherrently wrong with a cross over designed by Madisound any more than there is anything right with a crossover designed by some major speaker designer. They all have their share of successes and failures which are only revealed by careful listening.
JMHO folks.
