Our Review

Definitive Technology Dymension DM80 Flagship Tower Speaker Review


Definitive Technology has long been synonymous with high-quality audio equipment, and their commitment to excellence is evident in their lineup of speakers. The Dymension DM80 Flagship Tower Speaker stands as a testament to their engineering prowess, positioned as a premium offering in the home theater market. With its advanced features and design, the DM80 is poised to cater to audiophiles seeking a superior listening experience.


The Definitive Technology DM80 boasts an imposing stature at 49.4 x 11.3 x 16.0 inches, and a hefty weight of 83.1 lbs, indicative of its robust construction. The speaker's black color scheme exudes an elegant and understated aesthetic that should complement most home decor. The build quality is exemplary, with high-grade materials and thoughtful design touches, such as the aluminum base that adds stability and reduces the risk of toppling.

Included accessories like the adjustable hard floor glides and carpet spikes ensure the DM80 can be securely positioned on various surfaces, enhancing both practicality and performance.

Speaker Components

The DM80 features a sophisticated driver composition, including dual 1-inch aluminum oxide dome tweeters and four 5.25-inch BDSS™ midrange/midbass drivers with Linear Response Waveguide™. This combination promises to deliver crisp highs and rich, detailed mid-tones. The fully balanced, adjustable Bipolar Array extends the soundstage, creating an immersive listening environment.

The integration of a 12-inch subwoofer and dual 12-inch passive radiators constitutes a formidable subwoofer system. This inclusion is a significant advantage, as it minimizes the need for separate subwoofer units, streamlining the home theater setup without sacrificing deep bass performance.


The DM80's specifications are impressive, with a wide frequency response of 23 Hz–30 kHz (-10dB) and a more accurate range of 28 Hz–23 kHz (-3dB). The Intelligent Bass Control feature allows users to fine-tune the bass output, ensuring a balanced sound that doesn't overwhelm the mid and high frequencies.

While the optional DM90 Height Module is sold separately, it offers an additional dimension to the sound by supporting Dolby Atmos and DTS:X audio formats, creating an even more enveloping home theater experience.

Connectivity and Compatibility

With a nominal impedance of 4Ω (8Ω compatible) and a sensitivity of 90dB, the DM80 is designed to work with a wide range of amplifiers, from 50 to 300 watts. This flexibility is a boon for users with existing amplifiers or those looking to upgrade their systems without compatibility concerns.


The DM80 shines across various music genres and content, delivering a sound quality that is both expansive and precise. The frequency response ensures that the speaker captures the full spectrum of sound, from the lowest bass to the highest treble notes.

The effectiveness of the bipolar design cannot be overstated—it disperses sound in a way that fills the room, creating an engaging and lifelike audio experience.

Listening Experience

Midrange clarity is critical for vocal and instrumental accuracy, and the DM80's midrange drivers excel in this regard. Treble precision is equally impressive, thanks to the high-quality tweeters. The bass performance is robust and controlled, with the built-in subwoofer system providing a solid foundation for the overall sound profile.

The adjustability of the bipolar array is a standout feature, allowing users to tailor sound dispersion to their rooms' acoustics, enhancing the listening experience.

Installation and Setup

Setting up the DM80 is straightforward, with clear instructions and intuitive design facilitating the process. The aluminum base not only adds to the stability of the speaker but also simplifies placement. Optimal configuration is key to achieving the best sound, and the DM80 offers the flexibility to experiment with positioning to find the sweet spot in any room.

Pros and Cons

The Definitive Technology DM80's advantages are numerous, from its wide frequency response and powerful subwoofer system to the advanced driver technology and elegant design. However, the fact that the optional DM90 height module is sold separately can be a drawback for those looking to immediately expand their audio setup. Additionally, while the grilles' non-removable nature maintains a sleek look, it may limit customization options for some users. The longevity of the GaN FET amps is yet to be tested, but the included warranty offers some peace of mind.

Final Thoughts

The Dymension DM80 is a compelling choice for users who prioritize sound quality and have a preference for a speaker that can deliver an expansive soundstage. It competes favorably with other speakers in its price range, offering a rich feature set and superior performance. While it's a significant investment, the quality of construction and audio output justifies the price for serious enthusiasts.

Additional Considerations

The technology employed in the DM80, including the GaN FET amplifiers, suggests a forward-thinking design that may offer future-proofing benefits. Definitive Technology's after-sales service and support are also factors to consider, as they contribute to the overall satisfaction with the product.

User Experience

Prospective buyers should consider their room size, acoustics, and sound preferences when evaluating the DM80. While the speaker's performance is exceptional, personal taste and specific use cases will dictate its suitability. As with any high-end audio equipment, auditioning the speaker in a proper setting is crucial to making an informed decision.

In conclusion, the Definitive Technology Dymension DM80 Flagship Tower Speaker is a formidable contender in the high-end speaker market, offering a blend of sophisticated design, advanced technology, and outstanding audio performance. Whether for music or movies, the DM80 is engineered to impress and is worthy of consideration by those seeking an audio experience that is both powerful and immersive.
