Hear what you've been missing
Have you ever struggled to hear the dialogue on your favorite TV shows and movie soundtracks? With a high-performance center channel speaker like Definitive Technology's CS-9040, that won't be a problem. This powerful speaker uses advanced driver design and solid build quality to reproduce movie dialogue and on-screen action with exceptional detail and presence. Add it to a pair of Definitive's Bipolar Series home theater speakers to enjoy a huge, three-dimensional soundstage with both music and movies.
High-tech drivers for exceptionally detailed sound
The CS-9040 has two 4-1/2" midranges flanking a 1" dome tweeter, for perfectly blended highs and mids. The aluminum dome tweeter is heat-treated to relax the crystal structure of the metal, then attached to a silk surround to help produce crisp, sparkling highs without a trace of harshness. And thanks to Definitive's Balanced Double Surround System (BDSS) driver design, which places a surround on both the outer and inner edge of the speaker cone to help it remain more stable as it moves, movie dialogue and special effects will sound clear, never muddy. There's also an upward-firing bass radiator in the top of the cabinet, so you'll hear just a little more boom in TV explosions and depth in bombastic movie scores.
Build a complete Definitive home theater system using perfectly matched bipole towers (see the BP-9020, BP-9040, BP-9060, and BP-9080X) and surrounds (see the SR-9040 and SR-9080).
Did you know?
Your new speakers will probably sound better after several weeks of use than they do right out of the box. That's because the material surrounding the woofers will loosen up, allowing the drivers to move more fully. Definitive Technology estimates a break-in period of 24 to 48 hours of playback before the speakers will deliver optimum sound quality. For more information and helpful tips, check out this article from Definitive's website about conditioning your speakers.

Features
Center-Channel Loudspeaker: The Definitive Technology CS9040 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.
Aluminum Dome Tweeter: The CS9040 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 CS9040 employs two 4.5" 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.
8" Bass Radiator: The top-mounted 8" bass radiator offers deeper, more impactful bass from the center-channel speaker without the need to add a separate, powered subwoofer.
Resonance-Free Cabinet: The Definitive Technology CS9040 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.
Acoustically Transparent Grille: The CS9040 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.
Binding Post Terminals: The speaker terminals are 5-way binding posts that will accommodate spade connectors, single or dual banana plugs, pin-connectors, and bare wire up to 10 gauge.
Mounting & Placement Options: The Definitive Technology center-channel loudspeaker can be placed on top of a flat-surface; such as a stand, shelf, cabinet or other piece of AV furniture. Integrated rubber feet make sure the speaker stays in place and does not scratch your furniture. To optimize its performance, please follow these simple guidelines.
- The center-channel speaker should be placed as close to the center of your television as possible without obstructing your view.
- To receive the full benefit of the built-in bass radiator, leave at least 1-2" of space between the top of the speaker and any surface.
Note: This center-channel speaker does not offer wall-mount compatibility.
BP9000 Series: The CS9040 is part of Definitive Technology's BP9000 series line-up of speakers. Definitive Technology's BP9000 series loudspeakers is its 4th generation of bipolar tower speakers, matching center channels, surrounds, and a height speaker module, designed to offer true, full-range performance for listeners seeking the highest quality audio reproduction.

Purchased CS9040 to accompany my BP9020's. Replaced older Bose surround system. Naturalness and clarity of sound is exceptional. Matches up well with the floorstanding speakers. When Def. Tech. says their center is "full range", they're not exaggerating.
