Definitive Technology Dymension DM90 Integrated Height Module Review

Introduction

Today's home theater enthusiasts seek not just to hear but to be completely enveloped by sound. The Definitive Technology Dymension DM90 Integrated Height Module promises just that—immersive, three-dimensional audio that elevates your listening experience, quite literally, to new heights. With Dolby Atmos certification, this height module is engineered to complement the DM80 and DM70 speakers, offering a cohesive and expansive soundstage.

Design

Aesthetics

The DM90's sleek black finish exudes a modern charm that fits seamlessly with contemporary decor. Its compact design, measuring 6.0 x 7.3 x 15.3 inches, ensures it doesn't draw undue attention, blending elegantly with the compatible DM80 and DM70 speaker series.

Build Quality

With a weight of 10.1 lbs, the DM90 is robust, indicative of quality materials and solid construction. However, the weight may raise considerations for secure mounting, especially in setups where the module needs to be perched atop existing speakers or affixed to a wall.

Grille

The grille, cloaked in acoustically transparent black cloth, is designed to preserve sound fidelity while protecting the internal components. The non-removable nature of the grille could be a drawback for those who prioritize ease of access for cleaning or inspection.

Features

Compatibility

The DM90 is versatile, supporting amplifiers with power ratings from 25 to 100 watts. This range accommodates a wide array of home theater systems, ensuring that users can integrate the module without the need for additional equipment.

Dolby Atmos Certification

Dolby Atmos represents the pinnacle of immersive audio technology, allowing sound to move in a three-dimensional space. This certification means the DM90 is not just capable of delivering superior sound but is also recognized for its ability to faithfully reproduce the precision of Atmos soundtracks.

Warranty

A 5-year warranty is a testament to Definitive Technology's confidence in the DM90's durability. It offers consumers peace of mind, knowing that their investment is protected over a significant period.

Performance

Audio Quality

The DM90's 1-inch aluminum oxide dome tweeter is meticulously crafted to deliver crisp, clear high frequencies, while the 5.25-inch BDSS™ driver with Linear Response Waveguide™ ensures a smooth, rich midrange. This combination yields a detailed and natural sonic character.

Frequency Response

Boasting a frequency response of 81 Hz–30 kHz, the DM90 covers a broad spectrum. However, the lower end of this range is somewhat limited when compared to specialized height modules that may reach down into the sub-80 Hz region. The real-world effect is a slightly less impactful bass response, which is typically mitigated by the presence of a dedicated subwoofer in most home theater setups.

Sensitivity and Power Handling

With a sensitivity of 90dB, the DM90 is efficient, capable of producing substantial volume with modest amplifier power. The recommended amplifier power rating suggests the module can perform well within a variety of power envelopes, from the modest to the more robust.

Installation and Setup

Mounting and Placement

Installation is straightforward, with the DM90 designed to sit atop the compatible DM series speakers. Its weight, while indicative of quality, will necessitate a secure and stable platform. Wall mounting, if desired, should be approached with care, ensuring that the chosen fixtures can support the module's heft.

Calibration

To achieve optimal performance, calibration is key. Users should follow the manufacturer’s guidelines and consider employing a receiver or processor's room correction software to fine-tune the module's output in relation to the listening environment.

Strengths and Weaknesses

Pros

The DM90's Dolby Atmos certification ensures it meets high standards for immersive audio playback. The inclusion of advanced technologies like the Linear Response Waveguide™ enhances sound dispersion and fidelity. The module's wide frequency response captures a substantial part of the audio spectrum, and its compatibility with a range of amplifiers adds to its versatility. The sturdy build and 5-year warranty offer additional value and reassurance to the consumer.

Cons

The grille's non-removability could pose a challenge over time, and the weight of the module might limit installation options or require additional hardware. Moreover, the lower frequency response limit, while ample for most applications, may not satisfy audiophiles seeking the deepest bass extension from their height channels.

Final Thoughts

The Definitive Technology Dymension DM90 is a well-crafted height module that promises to enhance any compatible home theater system with the magic of Dolby Atmos. Its sound quality, build, and warranty make it a compelling choice for those invested in the Definitive Technology ecosystem. While it has a few minor drawbacks, its strengths far outweigh them, especially for users who value aural immersion and a cohesive audio setup. The DM90 is a product that will delight those looking to bring cinematic sound into their homes with confidence and style.
