Dymension CI™ MAX premium in-ceiling speakers deliver precise sound for high-performance home theater and whole-home systems, with features like our patented pivoting woofer; discreet, flush-mount design; and robust weather protection.
Premium Definitive Sound
Definitive Technology’s most advanced acoustic innovations provide audiophile-grade home-theater sound.
Customizable Sonic Precision
A patented pivoting woofer and tweeter direct sound precisely where you want it.
Simple, Toolless Installation
Install speakers in minutes using an innovative toolless mounting system.
An ultralight, rigid, 1” aluminum oxide dome tweeter produces crisp, distortion-free highs that extend far beyond the range of human hearing. CI MAX Series features a pivoting tweeter on most models allowing for speaker placement in convenient locations while directing sound precisely where it matters most.
A three-position high-frequency attenuation switch (-2 dB, flat, + 2 dB) adjusts tweeter response to compensate for acoustic issues like overly bright- or dull-sounding rooms.
Dymension CI MAX’s light, stiff, mineral-filled woofers feature Definitive Technology’s revolutionary Balanced Double Surround System (BDSS™), which improves driver excursion and output, delivering superior punchiness and detail and a more even midrange throughout the room. Our patented Linear Response Waveguide™ extends both on-axis and off-axis frequency dispersion for more natural midrange and precise imaging and an open, airy sound.
Dymension CI MAX Series in-ceiling surround speakers all feature our patented pivoting woofer design. Pivoting woofers allow for speakers to be installed virtually anywhere—even sloped and coffered ceilings—while pointing sound exactly where you want it, for expansive, front-row sound anywhere in the room.
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.
Toolless Installation for fast, easy installs
A simple, two-piece system with pivoting “dog” arms installs effortlessly—no tools, no hassles. Pre-construction brackets are available for all Dymension CI models.
IP55-Rated Construction for robust weather protection
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.
Timbre-Matching for cohesive sound system
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.
