To "carry on" would I suppose mean "if Bud were still developing speakers, they would be like..." Otherwise you do vintage stuff (if drivers are still available) or some variation of "Bud-like". The later stuff with his name was produced after his death, so don't know how "Bud-like" they are (as he promoted the "expanding sound source" concept with tweeter above midrange that were both above the woofer, not MTM). Updating ("improving") on his concepts isn't highly "Bud-like" either. Philosophically, how "Bud-like" should it be to truly honor his name?
Specifically what makes this speaker any different than something else that Salk/Murphy/etc. would come up with?
