Offers smooth midrange performance with powerful bass response through a 6.5" bass-mid transducer and optimally tuned passive radiator.  Protrudes only a total of 8" from the ceiling.

The 6.5" transducer renders exceptional voice reproduction for improved intelligibility. The addition of a 1" pure titanium dome tweeter produces exceptionally clean sound reproduction and wide frequency response with moderate power capacity. To further enhance the low frequency and midrange performance of the 6061-CSD, anti-resonance fabrication has been included for the backbox enclosure. State-of-the-art CNC machinery allows the production of an incredibly strong, vibration free and low weight enclosure, which greatly improves sound quality over the entire spectrum. The front baffle is precisely angled to render accurate imaging and spatial detail, which assures faithful reproduction of dialogue and complex digital audio when used in a left, center and right configuration for video.
