The Genesis™ Forte line-source loudspeaker system is the culmination of a 30-year legacy of reference-level line-source dipole flagship loudspeaker systems dating back to the Genesis I in 1993, and even back to the IRS™ in 1977. Based on the popular Genesis Quartet, the Forte is a two-tower system that can be used in smaller rooms in which the four-tower Quartet would be overwhelming.

This state-of-the-art system is designed to reproduce music at live listening levels with virtually no restrictions on dynamic range, frequency response, or width, breadth and height of soundstage. The Forte is commissioned, not simply bought off the shelf – it is custom-built in the USA for the most dedicated and discerning music-lovers worldwide.


The Forte has a single 48-inch long ribbon midrange and fifteen1-inch ring-radiator ribbon tweeters (12 front, 3 rear) on a 1 ˝-inch thick solid cast acrylic non-resonant baffle. In addition, two 12-inch aluminum woofers plus a 1,000W servo-controlled bass amplifier are built into an attached bass enclosure.


In the mid and high frequencies, it is a dipole line-source. That means that there is minimal vertical dispersion, and horizontal cancellation in the plane of the drivers. The result is minimum floor and ceiling bounce and very much reduced side-wall reflections, resulting in solidly pin-point imaging and a wide and spacious soundstage.


Another advantage of a line source over a point source is that less power is needed to maintain the same loudness level with greater distance from the loudspeaker. Conversely, the same amplifier can sound far more dynamic at any given seating distance. Since small changes in distance result in far less change in sound pressure level, the listening "sweet spot" is also hugely extended, which means no more listening alone. The enjoyment of music becomes a family affair, and the listening chair becomes a listening couch or loveseat.


The single 48-inch midrange means that the critical frequencies from 120Hz to 3500Hz are covered with a single driver without crossovers in between.


The Genesis ring ribbon tweeter has been hailed as the "world’s best" by the audiophile press and customers. It has dispersion matching the midrange, which means that the sonic picture does not change with small movements of the head when you "bop to the music".


The two 12-inch woofers result in tightly controlled, smooth, and dynamic bass response in any room. Having a built-in servo-controlled bass amplifier means that there is no need to have to choose between using a muscle-bound amplifier with enough power to drive the woofers and a lower-powered amplifier having better harmonic, tonal and spatial characteristics. Servo-control results in extended bass response down to 16Hz with vanishing low distortion.


The Forte provides the dedicated audiophile with ample means to adjust the sonic presentation: a rear tweeter control tailors the high frequencies for different room environments; and gain and low-pass filter adjustment provide the ability to adjust the bass to match the listening room. A unique midrange phase/contour switch allows for adjustment of soundstage height for personal preference. Some of us prefer the orchestra seats in a concert hall, others prefer the circle seats: the Forte allows you to pick your favorite.


The sonic result of all this is to suspend belief as the majesty and intimacy of the actual musical event unfolds in your listening room. Concert halls, cathedrals and stadium events are rendered in life-like scale. The dynamics of a full-scale symphony orchestra or rock band will quite literally give you goose bumps. Soloists materialize before your ears as the intimacy of the performance make it seem like you can almost smell the perfume (or cigar smoke) of the singer. The Forte presents the performance in life-like scale.


When you have a pair of Genesis loudspeakers in your listening room, you have live music in your home and you have the best seats in the house. No rain checks, no lost tickets, no concertmaster with the flu, no substitute divas. The Genesis loudspeaker is the perfect expression of your love of music.
