Another advantage of the 7.5-foot line source is that the vertical spectral content of music is virtually the same throughout the length of the line source. Hence, the seating height does not matter with this speaker; unlike point source speakers where it is important for the ears to be aligned with the tweeter.
The Genesis 1.1 is also a dipole radiator. The midrange and tweeter drivers are mounted on a rigid Corian™ baffle with no enclosure. This has two advantages: firstly, it eliminates any enclosure or boxy colorations caused by cabinet vibrations or resonance.
Secondly, the dipole creates a cardioid pattern (like a figure-eight), which has its maximum output at the listening position and behind the speaker itself, and minimum output to the sides in the plane of the loudspeakers. This very effectively eliminates the bounce from the sidewalls. Hence, in conjunction with the line source, the Genesis 1.1 has no first reflection from the floor, ceiling or sidewalls. The net result is that there are far fewer detail-robbing room reflections from the room than other types of loudspeakers. With fewer spurious reflections to confuse your hearing, the program source emerges more clearly. Imaging is deeper, yet more focused.
This results in a loudspeaker system that is virtually room- independent. Also, because there are no phase and frequency distorting reflections created, one can be transported into the audience of the actual concert hall where the music was recorded.
4.2The Genesis Ribbon Tweeter
Reviewers in the Audiophile press have often remarked that the Genesis circular ribbon tweeter is the world’s best. It is a one inch circular planar ring-ribbon design crafted from an extremely thin membrane of Kapton with a photo-etched aluminum “voice coil” that is a mere 0.0005 inch thick. The entire radiating structure has less mass than the air in front of it! That is why it will accurately reproduce frequencies beyond 36k Hz.
The result of this design is a driver that has a rapid and uniform response to high frequencies, and has the speed of the best electrostatic designs without the high distortion and poor dispersion that is typically associated with them.
The Genesis 1.1 uses twenty-six of these tweeters configured as a vertical line source (twenty front-firing, and six to the rear). In addition to creating the dipole line source, the output is distributed over many
