Definitive Technology Dymension CI PRO – DC-65 PRO SI – Stereo In Ceiling Speaker

Pivoting Aluminum Oxide Tweeter
Aluminum oxide dome tweeter pivots to point crisp, clear sound anywhere, for lifelike sound with uncompromised clarity and imaging independent of speaker placement.

Mineral-Filled Woofer
A light, rigid, mineral-filled woofer, reproduces rich, clear music and movie soundtrack. Dymension CI in-ceiling and in-wall speakers are available with a 6.5- inch woofer or for even more powerful sound and deeper bass, an 8-inch woofer.

IP55 Rated
Stunning sound doesn’t have to be limited to indoor spaces. With IP55-rated protection against dust and low-pressure water streams, trust that you can bring premium sound to any space, including high-humidity environments and outdoor areas. Crossovers feature covers that protect them from the elements.

Discrete Design
Integrated frames and baffles; paintable, micro-perforated magnetic grilles; and a flush, border-free design mean speakers fade into the background for a virtually invisible appearance that’s in perfect harmony with your space.

Simple Installation
A simple, two-piece system with pivoting “dog” arms / doglegs installs effortlessly with no specialized tools, and no hassles. Pre-construction brackets are available for all Dymension CI models (sold separately).

Multiple Sizes & Applications
Multiple woofer sizes provide unparalleled design freedom to strategically position speakers within your home or business. Whether you seek seamless integration in compact spaces or crave room-filling audio in large areas, the choice of 6.5” or 8” woofers empowers you to sculpt a sonic landscape that balances form and function. Additionally, the DC-65 PRO SI, with its two inputs and dual voice coil woofer, produces stereo sound in a single round ceiling speaker – allowing fitment in small spaces that can be impractical for speaker pairs, like kitchens, showers, entryways, and under eaves.

Timbre Matched
With Dymension, fidelity runs in the family: Combine timbre-matched Dymension, Dymension CI, and Mythos speakers and Descend Series subwoofers to design the high-performance home theater system of your dreams or the perfect sound system for any space.
