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. Itʼs 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
Most audio experts agree that the ideal surround speaker system would have 5 identical truly full range speakers at every position. But most rooms and setups canʼt accommodate 5 identical large speakers. So we engineered the next best thing – a center speaker with robust bass response that fits on a shelf.

The CS-8040HDʼs bass radiator gives you full, rich center channel sound
The CS-8040HD features two patented 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.
