Features Center-Channel Loudspeaker: The Definitive Technology CS9080 center-channel loudspeaker delivers immense clarity and focus to the vocal range, accurately reproducing even the most demanding audio soundtrack content so you can experience every detail of your home theater. An aluminum dome tweeter, high-performance midrange BDSS drivers, and an integrated powered subwoofer with Intelligent Bass Control let you hear and feel every note as the artist intends. Aluminum Dome Tweeter: The CS9080 center-channel loudspeaker features one 1" aluminum dome tweeters for crystal clear highs that bring the most demanding audio soundtracks to life. The Definitive Technology tweeter is designed to play higher in frequency than what is heard by the human ear, creating an authentic reproduction of sound as the artist intends in the studio or concert hall. BDSS (2nd Gen) Drivers: The Definitive Technology CS9080 employs two 5.25" midrange cone woofers with patented Balanced Double Surround System (BDSS) technology (2nd generation). BDSS technology improves driver excursion which results in the selected driver producing bass output usually associated with a larger driver, while retaining the improved dispersion and midrange definition of a smaller driver. Integrated Powered Subwoofer: The CS9080 contains a integrated powered subwoofer that consists of a top-firing 8" woofer and 300 watt amplifier designed to extend the frequency response and dynamic range of the center-channel speaker. The best loudspeaker is one that reproduces balance between the highest highs down to deepest lows as accurately as possible. The integrated powered subwoofer offers deeper, more impactful bass from the center channel speaker without the need to add a separate powered sub. Intelligent Bass Control: Intelligent Bass Control is Definitive Technology's latest advancement that offers enhanced bass while maintaining overall mid-range tonal balance. Intelligent Bass Control gives you the ability to modulate deep bass up or down in level while simultaneously maintaining optimal mid-range clarity regardless of where the bass control is set. Simply rotate the dial on the back of the loudspeaker to your preferred bass setting and the speaker will do the rest. Definitive Technology recommends starting at the mid-point and then adjust to your preference from there. 10" Passive Radiator: Definitive Technology has paired the center speaker's 8" powered subwoofer with a top-firing 10" passive radiator for even bigger, deeper, louder bass that you can hear and feel. Acoustically Transparent, Resonance-Free Cabinet: The Definitive Technology CS9080 uses a resonance-free cabinet for high performance, distortion-free sound. The speaker cabinet's maximum rigidity with strategically placed bracing improves imaging while reducing resonance, further reinforcing the speaker's clean and powerful sound. The CS9080 loudspeaker's cabinet is wrapped in an acoustically transparent cloth grille for unaltered sound. Thanks to the speaker's acoustically transparent grille, you'll enjoy the subtle elegance of the speaker design without having to remove a speaker grille to enjoy natural, uncolored sound. Speaker & Line Level Inputs: The Definitive Technology CS9080 center-channel loudspeaker is fitted with both speaker-level (binding post) and line-level (LFE/mono-RCA) inputs.
