  • Page 2 The Genesis 2.2 is the result of technologies developed and refined over the past 40 years in loudspeaker design. The G2.2 loudspeaker system was created for the music lover who knows (almost) no compromise. It is designed to reproduce music (and film) at live listening levels with virtually no restrictions on dynamic range, frequency response, or imaging capabilities.

  • Page 4 a b s o l u t e f i d e l i t y Set-up Guide Now that you have your new Genesis 2 loudspeaker system, we realize that you can’t wait to hook it up and start the music! However, this is a big, complex system and we want you to set it up correctly and more importantly, safely.

  • Page 6 To remove the contents of all the crates, you will need help. The G2.2 loudspeaker system with crates weigh a total of 1,400 lbs. Each woofer tower weighs over 220 lbs, and each tweeter tower weighs over 150 lbs and they have to be lifted out of the shipping crates.

    “spike cups”. These defeat the purpose of having a spike in the first place! Use a copper penny – the weight of the speaker on the spike will create a depression in the penny, and this point is what will efficiently transfer vibration to the floorboards.

    a b s o l u t e f i d e l i t y retract the spikes first. This will avoid causing damage to the acoustic suspension and to your floor. If you have very light and resonant floorboards, you may need to place a heavy slab of marble, slate, or granite under the loudspeaker to avoid exciting the floor.

    Do NOT use this method of connection with Class D power amplifiers that have both +ve and –ve speaker outputs floating above ground. Some of these amplifiers have as much as 36V on their speaker “ground”, and this will damage the Servo-Controlled Bass Amplifier.

Each end of the SBI has a grounding alligator clip on a flying green lead.

    a b s o l u t e f i d e l i t y Tuning the system Music is the best way to begin to fine-tune your setup. We suggest that video sources be used only after you have setup the system to properly reproduce music.
  • Page 16 If you have the speakers only 20% away from the front wall, and you are not getting enough front to back depth (the singer not appearing behind the speaker enough) pull the midrange tweeter panels away from the front wall a little bit at a time. If you do not have them pulled far enough away, you may not have enough front to back depth.

  • Page 17: Phase Control

    When properly set up very little sound should appear to come directly from the speaker, instead, the sound stage should extend far beyond the left and right edge of the loudspeakers and they should have tremendous front to back depth. When the recording is...

  • Page 19: The Refinement Stage

    If you find that the sound is not spacious enough or you are not getting enough front to back depth, pull the speaker away from the front wall. This is typically preferable to separating the two speakers too far, and will almost always give you better depth and soundstage information.

  • Page 23: Design Philosophy

    a b s o l u t e f i d e l i t y 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.
  • Page 24 This very effectively minimizes the bounce from the sidewalls. Hence, in conjunction with the line source, the G2.2 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.
  • Page 25 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. This is why the G2.2 loudspeaker system uses a single 48inch-long ribbon per channel as a dipolar line-source to reproduce these critical frequencies.
  • Page 26 The transducer used in a servo system must be strong enough to withstand the high current approach of the servo, and yet delicate and light enough to react extremely quickly. The G2.2 features a total of four front- and four rear-firing 8-inch woofers per channel –...
  • Page 27 Servo-controlled Amplifier One problem, however, of metal cones, is that of greater mass (even ones as light as the ones used in the G2.2). To over come this, Genesis had to build an amplification system of great power, and high damping factor. The servo system also places...

A further advantage to separating the amplifier modules of the left and right woofer towers is that if you are lucky enough to have multiple 20amp circuits in your listening room, you can power each woofer tower with a separate circuit! This allows for even better...
