Genesis 2.2
The Technology The Genesis 2.2 loudspeaker comprises four “towers”: two midrange/tweeter wings and two bass columns. Each tower is over 6 feet tall (183cm), and the cabinet is made of a vibration damping and resonance-control acrylic/composite sandwich material. The tweeters and midrange ribbon are mounted on a solid 1.5-inch slab of high-molecular weight cast acrylic. The rationale for the four-tower system separating the woofers from the midrange/tweeters is to allow the placement of the highfrequency wings to optimize imaging and soundstage, and the placement of the woofer towers to optimize in-room bass response. Design Philosophy Nothing has changed in theoretical acoustics since Lord Rayleigh’s original book on acoustics published in 1877. There are still only two proper ways for a transducer to propagate sound in a room: a point source and a line source. Anything else, or everything in between, is a compromise. In order for all frequencies of sound from the loudspeaker to reach the listener at exactly the same time, a coherent wave front is important – not just “timealignment” of drivers. The ideal is either an infinitely small pulsating point or a pulsating line with a size on the order of the room dimension. Obviously, a line-source is much easier to mechanize than the ideal point source. The line-source (if large enough), can approximate the ideal, and in doing so, provide sufficient radiating area for dynamically and spatially realistic sound reproduction. The Genesis 2.2 is a line-source that is 4 feet long (nearly the half the room’s entire height). Very importantly, the line source has no vertical dispersion at any frequency. Hence, there is no sound bouncing from either the floor or the ceiling.
