Talk about mumbo jumbo!
Sounds to me as though all this(that is described) would do is to create
confusion.
If people like it, fine. But it is surely not suppressing HRTFs--
it is just presenting a sort of diffuse effect. The HRTFs
are still there--they are just operating on a confused and confusing
situation.
So what? Bose (and widely spaced omni recording peopple!)latched on to
something a long time ago--a lot
of people apparently do not like direct radiation stereo and prefer a lot
of sound arriving in odd ball ways. Fine by me."If that's your pleasure,
go on, live that way".
But no mumbo jumbo explaining
why some people like confusion is needed.
Incidentally, turning the cones inside out probably makes them work
badly but it does
not actually change their radiation pattern
all that much except in very high frequencies(where
they should not be being used anyway).

the cones of the speakers are turned inside out so that they
become "omni" (ish) sources. Each side has two drivers. As far as I
remember they are twisted at 90 degrees with respect to each
other - e.g. one is pointing sideways towards the centre stage, one
is pointing downwards towards the floor. According to the inventor
this supresses our brain's use of HRTFs to locate the source, thereby
managing to create a virtual image between two vertically spaced speakers.
(I apologise if I'm quoting him wrongly, but it was something like that)
BTW, one must be either Ferengi or Dutch to turn 'Blumlein'
into 'Bloomline'.
ja, verschrikkelijk, toch? En dan ook nog de Ambisonic / Calrec Logo
inpikken!
groeten, Justin.
