Klipsch DS-180CDT In-Ceiling Speaker

Klipsch DS-180CDT In-Ceiling Speaker (Each) at Vinyl Sound Toronto Canada

The DS-180CDT is an 8-inch in-ceiling speaker from Klipsch (Indianapolis, Indiana, USA), available at Vinyl Sound in Toronto, Canada. Built on the same Tractrix® horn technology that defines Klipsch's premium architectural and box speaker lines, the DS-180CDT delivers 94 dB sensitivity , a wide 100-degree coverage angle , and a frequency range of 55 Hz to 20 kHz — all within a tool-free, bezel-free installation package designed for clean integration into any room.

Horn-Loaded Performance with Tractrix® Technology

At the core of the DS-180CDT is Klipsch's signature Tractrix® horn, the same horn-loading principle used in the brand's Reference and Reference Premiere loudspeaker lines. The 1-inch Silk Dome tweeter is mated directly to this round Tractrix® horn, reducing distortion and delivering high-frequency clarity with wide, even dispersion. The result is the kind of direct, dynamic sound that Klipsch has refined since 1946. Unlike conventional in-ceiling designs that rely solely on a dome tweeter without a waveguide, the Tractrix® horn provides controlled output at higher volumes while maintaining efficiency — making the DS-180CDT easy to drive from multi-zone amplifiers and AV receivers alike.

Controlled Dispersion Technology and Pivoting Tweeter

The "CDT" designation in the DS-180CDT stands for Controlled Dispersion Technology, a Klipsch engineering feature that allows both the tweeter and the woofer assembly to be aimed up to 15 degrees off-axis. This means the speaker can be angled toward a primary listening position even when mounted in the center of a ceiling, dramatically improving on-axis frequency response for seated listeners. The pivoting 1-inch Silk Dome tweeter complements this flexibility, allowing installers to fine-tune directionality room by room during the setup process.

Patented SkyHook Tool-Free Installation System

The DS-180CDT uses Klipsch's Sky Hook® Cinch by Swarm Installation System, a patented tool-free mounting mechanism engineered to reduce installation time by up to 75 percent compared to traditional dog-leg speaker installation. When the speaker is inserted into the cutout hole, the dog legs engage automatically at a preset clamping force, eliminating the risk of overtorquing and damage to the ceiling material. For uneven ceiling surfaces, a quarter-turn adjustment of each dog-leg screw achieves a flush, level finish. The required cutout diameter is 9.57 inches, and the mounting depth is 4.65 inches. An optional fire-rated enclosure (ME-800-C) and install kit (IK-800-C II) are available separately for code-compliant whole-home audio builds.
