Definitive Technology Dymension DM20 Slim Center Channel Speaker Review

Introduction

A center channel speaker is the linchpin of a home theater audio system, anchoring dialogue and on-screen action directly to the visuals, and providing a seamless audio transition from left to right. Definitive Technology is a brand that has consistently delivered high-quality audio equipment, and their latest offering, the Dymension DM20 Slim Center Channel Speaker, promises to uphold that reputation by enhancing the clarity and depth of home theater setups.

Design

Aesthetics

The Definitive Technology Dymension DM20 boasts a sleek and contemporary design that is both visually appealing and functional. The slim profile is an elegant solution for those looking to save space without compromising on sound quality. At 5.3 x 30.5 x 6.5 inches and weighing 22 lbs, it's substantial enough to promise serious performance, yet designed to blend seamlessly into the modern living room with its minimalist black color scheme.

Build and Materials

The speaker's acoustically transparent black cloth grille is a stylish touch that also serves a purpose, allowing sound to pass through unimpeded. However, the non-removable nature of the grille means that listeners are unable to peek at the drivers or customize the look. The horizontal orientation is standard for a center channel and should accommodate most home theater configurations.

Features

Advanced Driver Array

At the heart of the DM20 is an advanced five-driver array, including a 1-inch aluminum oxide dome tweeter flanked by four 4-inch midrange woofers. This setup is engineered for dynamic, full-bandwidth audio, ensuring that whether it's the subtle whisper of dialogue or the full force of an explosion, the DM20 can handle it with finesse.

Frequency Response and Impedance

The frequency response of 64 Hz–30 kHz (-10dB), and more critically, 91 Hz–23 kHz (-3dB), may not match the lowest bass notes of some high-end speakers, but in practice, this range is ample for a center channel, which primarily handles midrange frequencies. The nominal impedance of 4Ω, which is 8Ω compatible, means the DM20 can work with a wide range of amplifiers, though it shines brightest with a recommended 50-200W of power.

Compatibility and Integration

Timbre-matching across the Definitive Technology series ensures that the DM20 can integrate seamlessly into an existing setup, providing a consistent sound profile. The speaker's disappearing design is a nod to aesthetics, allowing it to virtually vanish in the room, focusing attention on the sound rather than the speaker itself.

Performance

Sound Quality

The DM20 delivers superior vocal clarity, which is paramount for a center channel speaker. Dialogue is crisp and precise, with no signs of muddiness. The aluminum oxide tweeter contributes to a bright and detailed high-end, while the long-throw midrange woofers ensure that the speaker has enough heft to convey impact when needed. With a sensitivity of 89dB, the DM20 is quite efficient, translating into less power needed to produce high volume levels.

Room Integration

Due to its slim and wall-mountable design, the DM20 offers versatility in room placement. It can be placed under a TV on a stand or mounted on a wall, providing flexibility for various room sizes and configurations. Its performance remains consistent across different setups, though it excels in environments where its advanced driver array can deliver sound unobstructed.

Pros and Cons Breakdown

The Definitive Technology Dymension DM20's full-range sound, superior vocal clarity, and versatile placement options are significant advantages for any home theater enthusiast. The timbre-matching feature ensures a uniform soundstage when paired with other Definitive Technology speakers. However, the limited low-frequency response means it might not satisfy those seeking earth-shattering bass without a subwoofer. Additionally, the non-removable grille could be a drawback for users who prefer customization.

Final Thoughts

The Definitive Technology Dymension DM20 Slim Center Channel Speaker is a well-crafted piece of audio equipment that offers excellent sound quality and a sleek design. Its performance in vocal clarity makes it a standout choice for movie dialogue and on-screen action. It is best suited for users who value aesthetic minimalism and those looking to complement their existing Definitive Technology setup. With a 5-year warranty and a thoughtful design that caters to both auditory and visual senses, the DM20 stands as a compelling option in the competitive home theater market, deserving consideration for its blend of style, sound, and seamless integration.
