The Manipulated Vortex Waveguide

The Manipulated Vortex Waveguide tm or MVW for short is an electro-mechanical system that harvests and uses the energy from both sides of the loudspeaker transducer. A more loudspeaker centric term for this technology would be a Frequency Independent Virtual Compression Labyrinth Horn.

This alignment produces a de-correlated reverberant field yielding several benefits over more conventional designs:

  • Increased loudspeaker sensitivity
  • Greater perceived clarity
  • Enhanced spacial immersion and imaging
  • Enhanced dynamic response
  • Reduction of adverse environmental interactions

The Big E design philosophy begins with the study of conventional loudspeaker design with an emphasis on Folded Horns beginning with the Jensen Imperial and other Jensen designs. It is noted that when employing such large horns in a small listening environment the bass frequencies from such a correlated source could react adversely with the room causing severe node and anti-node behavior or even producing a standing wave that could be almost completely canceled if placed in a room of  proper proportion to do so. The recommended remedy of such a situation is to place objects such as furniture in the output path of the horn to cause a breakup to the single source signal into multiple reflections or de-correlation. Contemporary researchers such as Dr. Earl Geddes and Floyd Toole as well as loudspeaker designers such as Duke LeJeune and James Romeyn have moved this theory forward with the study of Early and Late Reflections as well as Diffraction and High Order Modes.

 At Big E we recognize that sine wave source input and point source theory create a useful simplified mechanism for the study of sound wave propagation and can be fundamental in the development of fine loudspeakers. For us, however, these mechanisms are guidelines not goalposts. Our goal is life-like natural sound. Sound in nature is very rarely created by a sine type signal radiating from a single point in space. Rather, sound in nature is the result of multi-turbulent hydrodynamic flows such as that created in the human larynx. To complicate matters our target audience is NOT a microphone and measurement device but the human ear-brain interface. It is the human auditory processing system that is the final focus of our designs. Dr. Geddes states that at frequencies above 500 cycles per second or Hz the wavelength is short enough to provide numerous pseudo-random reflections making placement of loudspeakers producing such a frequency range in most environments largely irrelevant. It is the frequencies below 500Hz that need the most consideration or treatment. The ability to place loudspeakers pretty much wherever the user may need them and still get excellent performance, rather than having to re-arrange the room or environment to accommodate speaker placement requirements, is a major design goal for Big E.

Our Loudspeaker Design Goals Are:

  • Enhanced natural dynamics
  • Resistance to adverse environmental/room interactions
  • True fundamental frequency response balanced with pleasing psycho-acoustics
