Clarity and Impact

The CS9040 features high-performance BDSS mid/bass drivers, aluminum dome tweeters, and an integrated 8" passive bass radiator. With the CS9040, you’ll hear center channel audio with a level of full range clarity and impact that’s unlike anything you have ever experienced before.

Integrated 8“ Bass Radiator for full range sound

The center channel is critical for more than just vocal clarity, it is also the location of much of the sound effects audio in films. Where most competitive center channel offerings narrowly focus only on reproducing voice dialog, the CS9040 provides full range representation of your center channel audio. The CS9040 achieves this through the integration of an 8” bass radiator, which works in harmony with the CS9040’s BDSS woofers to effectively double their bass producing surface area. That translates to richer, more impactful sound—front and center where you expect it. In addition, the presence of a bass radiator in the center of your soundfield supports more even bass distribution throughout the room.

Balanced Double Surround System™for the best seat in the house

At the heart of the CS9040’s speaker array are two innovative 4.5" Balanced Double Surround System™ drivers, designed to always place you in the best seat in the house. BDSS improves driver excursion, allowing the CS9040’s mid/bass drivers to play lower and blend with its built-in subwoofer and bass radiator.

Because this technology is utilized across the entire BP9000 Series, when integrated with other BP9000 models, the CS9040 contributes to a more uniform midrange soundstage throughout your listening environment. That means anchored, centrally focused dialog; full range reproduction of scores and sound effects; and a seamless flow of panned audio from loudspeaker to loudspeaker.

Aluminum Dome Tweeters for crystal clear highs

The CS9040’s Aluminum Dome Tweeters feature ultralight, rigid construction that enables them to play significantly higher frequencies than we can hear with incredibly fast and accurate transient response. This provides effortless, distortion-free performance within and beyond the audible range—perfect for the enjoyment of high resolution audio.

Details Make The Difference

Designed for Performance

It’s not just the full range sound and detailed driver performance that make the CS9040 the workhorse of your home theater sound system. We’ve left no stone unturned in engineering optimal center channel experiences and the CS9040 features resonance-free cabinetry and a disappearing design that’s ideal for movie night.

Anti-Resonant Constructionfor clean and powerful sound

Strategically-placed bracing creates maximum rigidity with a totally inert, resonance-free cabinet for improved imaging and accuracy.

Disappearing Designfor focus on what matters

The CS9040 is wrapped in an acoustically transparent black cloth grille that won’t affect the sound. And as soon as you dim the lights, they disappear into your room—so you can focus on the movie, not your speakers.

Beautiful Music, Too

Not Just for Home Cinema

All the advances that make the BP9000 series the ultimate home cinema speaker system apply to beautiful music reproduction as well. That’s why the CS9040 is also revered for its extraordinary musicality—it’s like sitting with the mix engineer when watching concerts or music videos, or when listening to multichannel audio from FLAC, Blu-ray or SACD sources.
