Thanks to a new patent-pending gimbal mechanism, known as Controlled Dispersion Technology (CDT), both the high and low frequencies of the CDT-3650-C can be directed towards the listening area. Because the tweeter is independently adjustable from the woofer, this speaker offers even more precise localization. With integrated whole-house audio systems becoming more popular than ever, Klipsch designed the CDT-3650-C to meet the market's demand for a high-performance in-ceiling loudspeaker that easily challenges the inherent limitations of fixed locations. The CDT-3650-C features a 1" aluminum tweeter mated to a swiveling 100-degree Tractrix Horn. This swiveling horn design dramatically increases efficiency by enabling the speaker to produce more output using less energy. Additionally, a horn-loaded tweeter works well in instances where you want to point the sound to a specific location because it has more controlled directivity than a conventional dome tweeter. The speaker's 6.5" copper-colored IMG woofer also has great positioning capabilities. It can rotate a full 360-degrees and then shift 15-degrees in any direction. This flexibility combined with the swiveling tweeter puts you in complete control of where the sound will go.
