Description
Standing 56.5 inches tall and only 12 inches wide, the Genesis 450XS is presented in a
bleached American Cherry wood. The Genesis 450XS is a loudspeaker system capable of
delivering live listening levels across the entire frequency spectrum. By means of active
servo bass, response down to 22 Hz is achieved and the full range and impact of the
symphony orchestra can be reproduced.
The Genesis 450XS has four planar ribbon tweeters, three in front and one in the rear. At
the midrange, the 450XS employs two 6.5 inch, metal cone mid bass couplers that are out
of phase with each other. Also at the midrange is a 24 inch ribbon driver mounted in the
front of the cabinet. The bass frequencies are handled with two 12 inch metal cone active
drivers that are powered by a 1000 watt Genesis GSAT power amplifier that is built into
the unit.
Like all Genesis loudspeakers, the Genesis 450XS's are a dipole design producing sound
from both the front and the rear, one out of phase with the other. While the advantages of
a dipole design are many, the two main benefits are ease of placement in the room and a
greater degree of spacious natural sound reproduction.
Dipoles achieve their superior performance because they create a radiation pattern such
that the energy radiating to the sides of the speakers plane is nearly zero. So, with very
little acoustical energy reaching the side walls of your living room not only is placement
of the speakers easy but, remarkably, the listener is able to experience the music
unencumbered by the normal room aberrations which plague most other speakers.
The 450XS's magic is in the drivers
The tweeter used in both the front and the back of the 450XS series has been described,
by many reviewers in both the American and the foreign Audiophile press, as possibly
"the world's best". It is a 1 inch planar ribbon design and is hand-crafted from an
extremely thin laminated membrane of aluminum and Kapton and measures a mere
0.0005 inch thick. The advantage of incorporating such an extremely thin membrane is
that of low mass. The result of this design is a driver that has a rapid and uniform
response to high frequency transients and has the speed of the best ribbon/electrostatic
designs without the high distortion and poor dispersion that are typical.

Summary of Contents for Genesis Genesis 450XS
- Page 1 22 Hz is achieved and the full range and impact of the symphony orchestra can be reproduced. The Genesis 450XS has four planar ribbon tweeters, three in front and one in the rear. At the midrange, the 450XS employs two 6.5 inch, metal cone mid bass couplers that are out of phase with each other.
- Page 2 Lower distortion, greater frequency extension and tight control yield musically accurate yet “floor shaking” bass. The metal cone servo controlled woofer system of the Genesis 450XS is driven with a built in amplifier of unique design. Known as GSAT, the 450XS utilizes a technology of amplification first introduced by Genesis founder Arnie Nudell and is known as a switching amplifier.
- Page 3 450XS marked “input”. We strongly recommend that you do not use interconnects longer than 10 feet (3.2 meters) to connect the preamplifier output to your Genesis 450XS. On many preamplifiers, use of an interconnect that is too long will negatively affect the performance of your preamplifier because of the high capacitance of the cable across the output of your preamplifier.
- Page 4 Initial settings On the back of the Genesis 450XS there are three controls. They are labeled “tweeter”, “Gain”, and “Low pass”. Tweeter controls the volume level of the front tweeter. There is about a one dB range.
- Page 5 Turn the volume control of the GSAT amplifier up or down until the voice sounds correct. Concentrate on the mid bass regions (as opposed to the very low bass in your recording) to achieve a natural blend. The voice and the music accompaniment should sound as if it were cut from one cloth, not separate.
- Page 6 Further adjustments If the voice sounds “thin” or does not have enough “chest” to its sound, turn the woofers amplifier’s volume (gain) up till it does, or at this point, you may want to experiment with increasing or decreasing the low pass filter control. This control will raise or lower the frequency cutoff point of the woofer.
- Page 7 A Genesis loudspeaker system correctly set up, can and should provide a soundstage that is wall to wall and with pin point focus, the speakers disappearing completely on a recording containing such information.
- Page 8 1. This loudspeaker is a dipole and therefore there is sound coming from both the front and the back of the speaker. How the wall behind the loudspeaker is treated or not treated is important. Generally speaking, the Genesis loudspeakers prefer a live wall behind the speaker and a dead wall behind the listener.
- Page 9 Keep at it and remember to enjoy your music as you work on perfecting your setup. If you have any questions, feel free to contact us at Genesis. Note: Should your woofer amplifier unexpectedly turn off and you are unable to turn it back on, you have overheated the amplifier or have played it too hard.
