I told you I'd post BigE stuff here as it was released. The first tidbits of info about how they work can start coming out as the patent process is under way, and some protection is in place. Here's a release from the designers. Sounds like science fiction, until you hear the cabs.
Manipulate Vortex Waveguide Basic Theory
No force tuning of the driver occurs.
Audio transducers mounted in crossfired scoop loaded configuration, To provide better driver loading and dispersion.
Energy from rear of transducers is harvested, fractured and re-energized inside the Vortex Waveguide system.
Each fractured segment is time shifted in the waveguide prior to release
in the output flare port where it is encapsulated by the output energy
stream. The time shifted packets of auditory info are summed with the
output of the front of the transducers.
The resulting multi-time-shifting signal exits the front of the cabinet
encapsulated in the bass energy stream. This causes the creation of the
nearfield event horizon. The resulting auditory information emulates
sound creation in nature.
The decorrelated packeted information is summed by brain of the
listener into a correlated auditory information, as is done in nature.
The multitude of of slightly time shifted audio packets created are
reflection resistant and more natural sounding due to
the manner in which the information is transmitted to the listener.
The Vortex Event Horizon provides an expanded nearfield effect allowing
more efficient transmission of information to a larger audience area.
This also provides the ability of the MVW cabinent to transmit auditory
info beyond line of sight with minimal loss. The Vortex Event Horizon
will wrap around objects, obstructions, and up to boundaries providing a
self-adjusting nature to the nearfield.
All the factors combine to provide a very dynamic, efficient,
articulate, and natural sounding output to the listening audience.
