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’s no place to compromise and settle for second best. All Definitive CS series center channel 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.
Bass Radiator Technology Makes a Dramatic Audible Difference The CS-8040HD features two high-definition Balanced Double Surround System (BDSS) 4-1/2 inch drivers that are pressure-coupled to a 5 x 10 inch racetrack-shaped planar Low-Bass Radiator. The result is bass extension unheard of in a center speaker of this size and price. With the CS-8040HD you will fully realize the performance potential of the center channel program material as the movie director intended it to be heard. Its upward-firing bass radiator requires only 1" (25mm) of clearance, so it works perfectly whether you mount it in free-air or put it in a cabinet.
Proprietary Technology Delivers High Definition and Wide Dispersion The CS-8040HD features a D’Appolito array consisting of two cast-basket 4-1/2" (11cm) second generation BDSS midrange drivers surrounding a 1" annealed Pure Aluminum dome tweeter. These are the same drivers and tweeters used in the BP-8040ST bipolar SuperTower loudspeakers, making the CS-8040HD the perfect center channel match. The drivers feature Definitive’s Balanced Double Surround System (BDSS) technology that supports the speaker cone at both the inner and outer edges allowing longer, more linear excursion for greater clarity and finely textured inner detail. A new Linear Response Waveguide smoothes off-axis frequency response and disperses sound over a wider area for crystal clear intelligibility for every listener in the room. The 1” (25mm) tweeter is a pure aluminum dome, which has been heat-treated to relax the crystal structure and then coated with a ceramic to produce extended highs that reveal nuance and shimmer without a trace of edginess.
Non-Resonant, Low-Diffraction Cabinet Maintains Sonic Purity Definitive devoted as much Design and Engineering attention to the styling and construction of the 8040’s enclosure as any other part of its design. The tapered front of enclosure serves to make it appear slimmer and less obtrusive while also enhancing sound quality by minimizing cabinet diffraction distortion. But the enclosure’s most important job is to be totally inert and resonance free so as not to color the sound. Wherever a driver or low bass radiator is attached to the cabinet a second layer of heavy MDF (a low resonance wood composite) is placed to prevent the moving drivers from imparting vibration to the rest of the enclosure. Tap on the top of a CS enclosure to hear the solid “thud” of a stiff, well-damped cabinet instead of the hollow ring of less-well constructed speakers.
