8. undesirable contribution by reflected sound from these four surfaces which is why a lot of people put sound absorbers or diffusers at the first reflection point of the room In order to do that with a majority of rooms we make our loudspeakers dipolar Dipoles radiate the same but out of phase waveform from the front and rear in push pull fashion Thus the sound waves from the front and back of the speakers cancel out as they radiate from the sides and tops of the speakers which means that there is minimum radiation of sound to the sidewalls of the room The G7 1c uses the wall behind the speaker to give more depth to the soundstage and air to the speaker without detail robbing room reflections from the sidewalls Hence it has the advantages of omni directional speakers without the disadvantages With fewer spurious reflections to confuse your hearing the program source emerges more clearly Imaging is stable sharply focused deeper and spacious Transients are clearer and sharper 4 2 The Transducers The transducers in the 2 way G7 1c are all proprietary Genesis designed drivers manufactured to our exacting standards 4 2 1 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 Kaptone with a photo etched aluminium voice coil that is a mere 0 0005

17. o separate the speakers too far from each other This gives an unnaturally wide soundstage between the two speakers and creates problems beyond the unnatural width of the center stage It focuses the soundstage in between the two speakers and you lose the space and ambience of the musical performance If you find that the sound is not spacious enough or you are not getting enough front to back depth pull the speakers away from the front wall This is typically preferable to separating the speakers too far and will almost always give you better depth and soundstage information A word of caution though If you move the speakers too far from the front wall you may lose the focus of the image In order to achieve what the speaker is capable of we suggest you focus your efforts on a proper balance of soundstage elements that includes information beyond the left and right sides of the speakers front to back depth well behind the speaker excellent focus of instruments and voices with proper vertical information and mid bass fill A Genesis loudspeaker system correctly set up can and should provide a soundstage that is wall to wall with pinpoint focus the speakers disappearing completely on a recording containing such information With the G7 1c adding a ServoSub or two will result in the walls of the room melting away Ambience of large acoustic spaces is defined by low bass and the ServoSub adds that critical element when listening to
