Audiophile Appeal

Premium Definitive Technology acoustics in a designer- inspired, adjustable-width enclosure.

Sleek, low-profile designer cabinet adjusts to match television dimensions.

Weather-resistant, IP66-rated construction ensures reliable performance, indoors and in covered outdoor environments.

Premium Sound, Designer Aesthetics

XTDD Drivers for spacious, dynamic sound in every seat

Ultra-stiff anodised aluminium dome woofers and midrange drivers eliminate break-up and broaden dispersion for crisp, clear sound and a spacious, enveloping soundstage.

Aluminium Oxide Dome Tweeters for exceptional definition and realism

Rigid, well-damped Dymension™ Series tweeters deliver smooth extended response, crisp transients, and pin-point imaging for cohesive, lifelike sound that draws you inside the action.

Precision Crossovers for dynamic, balanced response

Meticulously tuned crossovers optimise systems for the most efficient driver performance. You’ll experience richer, fuller, sound—the kind you’d expect from full-sized speakers.

Slim Profile and Adjustable Width for a Streamlined Appearance

The 3C-65’s ultra-slim, wall-mount cabinet measures less than 2” deep; symmetrically adjustable extensions expand up to 6.75” to perfectly align with the dimensions of 65-inch class displays, for a cohesive look.

Acoustically Optimised Cabinet for Pristine Sonic Reproduction

A highly rigid, tuned aircraft-grade aluminium enclosure houses a 13-speaker array with each channel in its own acoustic chamber. You’ll experience the truest sound, uncoloured by cabinet resonances.

Timbre-Matching for uniform voicing in any configuration

Consistent sound across Definitive Technology speakers gives you the flexibility to mix and match speakers to build the ultimate system or a starter system that can expand as your needs grow.

All-In-One Sound Bar for big sound in an ultra-slim cabinet

Use a Mythos 3C-85 on its own or with a Descend subwoofer for larger-than-life sound in a low-profile, all-in-one system.
