The Technology
The 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 ribbon design crafted from an extremely thin membrane of Kapton with a photo-etched aluminium “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 reproduce accurately 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 ribbon/electrostatic designs without the high distortion and poor dispersion that is typically associated with them.
The G5 use two of these tweeters per channel. One front-firing, and the other wired to the crossover out of phase to the front tweeter and firing to the rear, creating a dipole. Dipoles radiate the same sound from both front and rear out of phase in “push/pull” fashion. Thus, the sound waves from the front and back of the speakers cancel out as they radiate from the sides of the speakers; which means that there is minimum radiation of sound to the sidewalls of the room.
The net result is that the G5 generate far fewer detail-robbing room reflections from the sidewalls 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.
Titanium Midrange
We sometimes say that the midrange is a window into the mind of a composer or a singer. And indeed, the midrange is where the “magic” is in a well-recorded musical event.
The G5 uses a Genesis-designed proprietary 4.5inch titanium coned midrange to cover this critical frequency spectrum. Machined out of one of the lightest and stiffest materials known, this low mass cone driver is one of the best midrange transducers ever made with nearly instantaneous transient response, enabling the G5 to sound lifelike and effortless.
The driver is housed in an enclosure that is open to the back. Thus, the midrange operates as a dipole too.
