moderate levels. The Genesis servo bass system reduces this
distortion to below one percent at almost any output level. It also
drives the woofer to constant acceleration, which makes its
frequency response totally flat!!
The servo system is a more proactive approach to controlling a
loudspeaker than high-damping factor and high current in the normal
amplifier. However, this also means that the woofer, the cables
attaching the woofer to the amplifier, and the power amplifier has to
be designed as an integrated system. Thus, the Genesis 5 is
designed with a built-in 500W servo amplifier for the bass section.
Aluminium-cone Woofers
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 G5 features three
8-inch aluminium cone long-throw woofers per channel.
While the servo system is able to ensure that the driver works
linearly as a perfect piston, it is unable to correct for distortion
caused by cone wobble, bending, and break-up. Hence, the drivers
were designed to minimize these non-linear distortions, allowing the
servo system to most effectively eliminate the linear distortions.
The woofers are a uniquely designed metal cone driver made for the
Genesis servo system. Made of a cone of solid aluminium, the
suspension and voice-coil have been maximized for long distortion-
free excursion so as to increase dynamic range. Our aluminium
cones are a magnitude stiffer than any plastic or paper cone on the
market, and virtually eliminate the problems caused by cone bending
and break-up.
The lowest break-up mode (where there can be any chance of
distortion at all) is at 6,000Hz – far above the 16Hz to 120Hz
frequency range at which these drivers operate. Therefore, the
driver is a perfect piston within the frequencies used. Thus, low cone
break-up distortion is inherent in the driver designed for the G5.
Unlike the mid-bass couplers, midrange and the tweeters, which
operate in dipole, the three woofers in the G5 operate in phase as
an omni-pole. All three woofers work in phase to control the air mass
of the listening room. This means that the surface area of the three
