Basically someone made the comment "Why would I pay $XXX for the Adire sub, when I can get the same thing from Ascendant for much less." Dan responded by saying something to the effect of "All XBL^2 drivers are not created equally"....meaning two subs that both have XBL^2 are not automatically going to have the same performance as you still need to design an entire sub around that technology. Dan's statement, ofcourse, is common sense to anybody with more than hollow space between their ears.....but for whatever reason Chad found this statement of the obvious offensive and decided to essentially trash Dan and Adire on AA's website and mention how he has found this new, wonderful, equally as good and free technology and will be dropping XBL^2.
I admittedly didn't pay attention to the online antics of either side
all I remember is AA leaving I don't recall Chad trashing XBL^2
saying other technologies are better/cheaper and offer the same benefits is undoubtably true... and that's no sign of anything else malicious that I've seen
Dan himself said in the Adire forum that XBL^2 is superior to LMT and split coil... and in some ways it is... but in a lot of important ways it's not
and those aren't even close to the only ways to achieve flat BL
I don't doubt Chad "found" something as good or better than XBL2...
to be honest Chad thought Dan was stating something negative about his products ... whether or not this was Dan's intention that's how it came off to a lot of people
There are plenty of ways to approach a speaker design and XBL2 while overall of Split coil, LMT, XBL2 comparison it happens to be seemingly the most efficent/lowest inductance you forget the other 4-5 ways to achieve a flat BL
and also XBL2 will have the lowest power handling of the bunch and the most costs associated with it...
seemingly adding on top of that royalties etc it's not a very positive thing for a lot of companies... and having a owner of the technology seemingly saying "your XBL2 isn't as good as my XBL2" will undoubtably ruffle already hurting feathers
just my 2 cents... as I try to see it from a more business point of view from both sides
