At the AES Convention in New York, the pro audio community witnessed significant advancements in low-frequency monitoring. For engineers seeking absolute precision in the lower registers, the release of the aes 2017: dynaudio 9s & 18s subs (video) highlighted an exciting transition in Dynaudio’s monitoring ecosystem. Designed to seamlessly complement the LYD nearfield monitor range—which we reviewed previously—these two subwoofers bring advanced DSP and exceptional transient response to professional control rooms.
Analyzing the AES 2017: Dynaudio 9S & 18S subs (Video) Launch
When examining the technical specifications presented in the aes 2017: dynaudio 9s & 18s subs (video), the 18S model immediately stands out due to its dual-opposing driver configuration. Powered by a high-efficiency 500W Class-D amplifier, the 18S utilizes two 9.5-inch MSP (Magnesium Silicate Polymer) woofers positioned on opposite sides of the cabinet. This design ensures that physical cabinet vibrations are balanced out, resulting in a cleaner, punchier low-end translation. The smaller 9S, on the other hand, utilizes a single 9.5-inch woofer powered by a 300W amplifier, making it an ideal choice for compact mastering suites and edit bays.
To understand how these subwoofers fit into modern hybrid workflows, it is helpful to look at how they compare to industry benchmarks. While top-tier manufacturers like Neumann offer excellent alternative acoustic solutions, Dynaudio’s onboard DSP presets set a new standard for integration. The built-in crossover filters are specifically mapped to align with Dynaudio’s active monitor lines, ensuring phase coherence across the crossover point without tedious manual measurement.

Technical Specifications and Comparison
Choosing the correct subwoofer requires analyzing cabinet dimensions, power handling, and driver configurations. Below is a breakdown of how the 9S and 18S compare based on the product rollouts:
| Name | Use | Price | Rating |
|---|---|---|---|
| Dynaudio 9S | Compact Nearfield Subwoofer | $1,099 | 4.5/5 |
| Dynaudio 18S | Mastering & Midfield Subwoofer | $1,999 | 4.8/5 |
Practical Studio Workflow Tips for Subwoofer Integration
Integrating a subwoofer into your mastering workflow is more complex than simply plugging it in and turning up the level. Our mastering engineers noted that the aes 2017: dynaudio 9s & 18s subs (video) serves as a perfect demonstration of how DSP technology can simplify calibration. Here are our top workflow tips:

- Utilize Built-In DSP Presets: If you are pairing the 18S with LYD series monitors, use the onboard DSP menu to select your exact monitor model. This automatically configures the crossover frequency and delay offsets.
- Phase Alignment: Make use of the sub’s phase correction settings. Play a continuous sine wave at your crossover frequency (typically 80 Hz) and adjust the phase control until you hear the quietest signal at the listening position when one monitor is polarity-reversed; then flip the polarity back for perfect alignment.
- Decouple the Cabinet: Even though the dual-opposing design of the 18S minimizes cabinet movement, placing your sub on a dedicated decoupling platform will further clean up your low-frequency transient translation.

Conclusion
As mentioned in the aes 2017: dynaudio 9s & 18s subs (video), the seamless integration of hardware and software DSP defines the future of low-end monitoring. Whether you opt for the space-saving 9S or the dual-driver power of the 18S, both units deliver the transient accuracy needed for critical mastering decisions. By extending your frequency response down to 16Hz (in the case of the 18S), these subwoofers ensure you hear every sub-bass detail with absolute clarity.
Frequently Asked Questions
Can I use the Dynaudio 18S with monitors from other brands?
Yes. While the Dynaudio 18S features built-in DSP presets tailored specifically for Dynaudio monitors, it also includes manual crossover controls. This allows you to set custom crossover points and time-alignment delays to pair the subwoofer with any studio monitors on the market.
What are the benefits of a dual-opposing driver design?
The dual-opposing driver design, as seen on the Dynaudio 18S, places two woofers on opposite sides of the cabinet. This configuration cancels out mechanical cabinet vibrations, preventing the subwoofer from shaking your studio floor and ensuring that all acoustic energy is projected cleanly into the room.
Is the Dynaudio 9S powerful enough for a mastering studio?
The Dynaudio 9S is highly precise and features a flat frequency response down to 22Hz. While it is excellent for small-to-medium mastering suites, larger rooms with significant acoustic volume will benefit more from the extra power, headroom, and dual-driver configuration of the 18S.
