Mythos 3C-65

Premium Sound, Designer Aesthetics

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

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.

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

3C-65’s ultra-slim, wall-mount cabinet measures less than 2” deep; symmetrically adjustable extensions expand up to 3.5” to perfectly align with the dimensions of 65”-class displays, for a cohesive look.

A highly rigid, tuned, aircraft-grade aluminum enclosure houses an 11-speaker array, with each channel in its own acoustic chamber. You’ll experience the truest sound, uncolored by cabinet resonances.

XTDD Drivers for spacious, dynamic sound in every seat 3XR™ Architecture for as much bass as a ported 12” subwoofer Aluminum Oxide Dome Tweeters for exceptional definition and realism Precision Crossovers for dynamic, balanced response Slim Profile and Adjustable Width for a streamlined appearance Acoustically Optimized Cabinet for pristine sonic reproduction
XTDD Drivers for spacious, dynamic sound in every seat
One, two, or four subs for smoother bass throughout the room

Timbre-Matching for uniform voicing in any configuration

Consistent sound across Definitive Technology models 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-65 on its own or with a Descend subwoofer for larger-than-life sound in a low-profile, all-in-one system.
