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. Because of this, Definitive pioneered the concept of full frequency range high-definition center-channel speakers.

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.

Built-in Powered Subwoofers Make a Dramatic Audible Difference
The revolutionary C/L/R2500 features a powerful built-in 8 inch powered subwoofer driven by a 150 Watt digital amplifier. Its upward-firing long-throw woofer only requires 1" of clearance, so it works perfectly whether you open-mount it or put it in a cabinet. The purpose of putting a subwoofer in the center channel, beyond putting more bass energy into the room, is to add full bass capability to the center channel itself. The difference this makes is absolutely audible and very dramatic. It gives you a truly full dynamic range and full frequency center channel that actually outperforms many floor-standing main L&R speakers, allowing you to set the center channel setting on your Dolby Digital receiver to “Large.” With the C/L/R2500 you will fully realize the performance potential of the center channel program material as the movie director intended it to be heard.

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/R2500 features Definitive-developed magnetically shielded high-definition cast-basket bass/midrange drivers for significant performance advantages in the areas of upper 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. In addition, the electronic crossovers in the subwoofer modules work together with the Linkwitz-Riley networks to perfectly blend the subwoofers with the bipolar arrays. The result is a symphony of sonic perfection that completely preserves the phase coherence, transient response and dynamic integrity of the original signal.
