Our Review

Definitive Technology DN8 Ultra-Performance Subwoofer Review


The Definitive Technology DN8 subwoofer is a compact yet robust low-frequency powerhouse designed to enhance the home theater experience. The importance of a subwoofer cannot be overstated; it brings depth and dimension to movies, music, and games by reproducing the low-end frequencies that small speakers cannot.

Design and Build


The DN8 boasts a sleek design that is both modern and understated, allowing it to blend seamlessly with most decor. Available in Glacier White and Midnight Black, these color options provide versatility for personal preference or room aesthetics.


The build quality of the DN8 is impressive. Definitive Technology is known for its attention to detail, and this subwoofer is no exception. The construction feels solid, and the materials used suggest durability and longevity.

Size and Placement

With dimensions of 12.8” x 12.0” x 13.1”, the DN8 is relatively compact for a high-performance subwoofer, making it easier to integrate into various room sizes. The permanently installed feet with rubber pads are a thoughtful touch, minimizing vibrations and ensuring stable placement.


Amplifier and Power

The Class D amplifier within the DN8 is noteworthy for its efficient power utilization. The subwoofer's 500W peak power and 200W continuous power are indicative of its ability to deliver powerful bass without unnecessary energy expenditure.

Frequency Response and Bass Radiators

The wide frequency response of 35 Hz to 200 Hz covers the essential range for deep and impactful bass. The inclusion of Dual 8” 3XR™ Configuration passive radiators is a design choice that maximizes the subwoofer's surface area to move air, resulting in more profound bass without distortion.


The DN8 offers a variety of input options, including LFE Single RCA and Speaker Left/Right 5-way binding posts. However, the lack of wireless connectivity might be a drawback for users seeking a cable-free setup.

Controls and Adjustments

The subwoofer features a comprehensive set of controls, including volume and low-pass crossover frequency potentiometers with a center detent, a phase control switch, and a status RGB LED, all contributing to the user's ability to fine-tune the audio output.


Sound Quality

The DN8 delivers rich, nuanced bass that can be felt as much as heard. The low-end is tight and controlled, without muddiness or boominess, which is a testament to the subwoofer's engineering.

The adjustable low-pass crossover frequency and phase adjustment are crucial for integrating the subwoofer with various room acoustics and speaker setups. These features allow users to tailor the subwoofer's output to complement the main speakers and room characteristics.

Power Handling

In a real-world setting, the DN8's power handling capabilities ensure that it can deliver consistent, dynamic bass in a variety of listening environments, from intimate viewing areas to larger home theaters.

Practicality and Usability

Setup and Installation

The setup process for the DN8 is straightforward, with clear instructions provided. Users can optimize performance through placement and calibration using the subwoofer's controls.

User Experience

The user interface of the DN8 is intuitive, with controls that are accessible and easy to understand. This enhances the overall user experience, allowing for quick adjustments and customization.

Comparison to Competitors

When matched against similar subwoofers in its class, the DN8 holds its own in terms of power, performance, and price. While some competitors may offer additional features like wireless connectivity, the DN8's sound quality and efficient power usage are competitive advantages.

Final Thoughts

The Definitive Technology DN8 is a well-rounded subwoofer that excels in both design and performance. The high peak power, efficient Class D amplifier, and detailed bass reproduction stand out as key strengths. The primary limitations are the absence of wireless connectivity and the potential need for additional amplification in larger rooms. Potential buyers who prioritize sound quality and efficient power usage will find the DN8 to be a compelling addition to their home theater setup.
