Optimum surround sound home theater reproduction places heavy demands
on the center channel speaker, which in many respects is the main
speaker in the system and often handles 50% or more of the program
material. It is no place to compromise and settle for second best. All
Definitive center channel series models are designed with the same
rigid standards and high performance goals as main left and right front
speakers and feature wide frequency response and extended dynamic range
with extraordinary detail and articulation.
Non-Resonant, Low-Diffraction Cabinets Maintain Sonic Purity
The resonant vibration of a loudspeaker's cabinet walls and baffles can
also impart coloration. The tri-chambered monocoque cabinets of all
Definitive L/C/R center channel models are constructed of extremely
thick, dense medite with foam damping pads and extensive internal
bracing. This virtually eliminates cabinet vibrations and resonance
which would otherwise interfere with the pure sound produced by
Definitive's high-definition drivers.
Definitive's High-Definition Die-Cast
Basket Drivers are an Engineering Marvel
The C/L/R2002 features Definitive-developed magnetically shielded
high-definition cast-basket bass/midrange drivers for significant
performance advantages in the areas of robust bass reproduction,
lifelike midrange clarity and dynamic range. These sophisticated
drivers are engineering marvels which incorporate deeply drawn
mineral-filled polymer cones, combined with butyl rubber dust caps and
surrounds, high temperature vented voice coils and massive magnet
structures. This combination of features assures high definition,
superb transient response, high efficiency, high power handling and
extended linear response. In addition, the aerodynamically designed,
non-resonant, cast-magnesium baskets minimize reflections of the sound
radiating from the back of the cones and preserve structural and
magnetic integrity.
Definitive's Moving-Coil Pure Aluminum Dome Tweeters
The accuracy of high frequency reproduction really sets apart a great
loudspeaker. The magnetic fluid-cooled moving-coil pure aluminum dome
tweeters Definitive developed for the bipolar SuperTowers are of a
unique design that synergistically brings together the performance
advantages of metal domes (greater clarity) and soft domes (smoother
sound and better dampening) in one state-of-the-art tweeter design.
The pure aluminum dome is specially annealed (to "relax" the crystal
structure) and acoustically loaded by a precisely configured acoustic
phase plug/lens (to assure perfectly controlled, absolutely linear
movement). The tweeter’s voice coil sits in ferro-magnetic colloidal
fluid which serves to cool the voice coil for exceptional power
handling and also damps the system for smoother response and sonic
accuracy. In addition, the unique silk surround provides better
dampening and wave termination. The audible benefits of all this highly
advanced engineering include velvety smooth extended high frequency
response (beyond 30 kHz), greatly reduced distortion, improved
transient response, notably higher definition and crystal clear
life-like clarity.
Phase-Coherent Crossovers for Perfect Driver Blending
The crossover network of a loudspeaker is the real heart of the system.
It is like the conductor of an orchestra, telling each driver exactly
when to come in and precisely how loudly to play. Here Definitive's
talented engineers really work their magic, perfectly blending the
sound of the various drivers into a sonically seamless, musically and
cinematically coherent whole. Our complex and sophisticated
Linkwitz-Riley designs, which utilize the finest components, are
masterpieces of electrical engineering. They are differential
crossovers which equalize the front and rear drivers separately for
both linear frequency and phase response of their summed output. Also
included are advanced technology Zobel Networks which provide a more
stable load for your amplifier. This makes the speaker easier to drive,
which results in smooth, more natural sound. The result is a symphony
of sonic perfection that completely preserves the phase coherence,
transient response and dynamic integrity of the original signal.
