Dynaudio 18S Dual 9.5 Powered Studio Subwoofer

Advanced DSP automatically mates with popular Dynaudio monitors

The 18S is engineered with Dynaudio’s advanced DSP modeling technology that acoustically mates the 18S to any of the company’s pro studio monitors from the BM and LYD series and above, essentially turning a two-way speaker into a three-way system. And if you combine the 18S with an LYD 48 stereo or surround setup, you’ll have a four-way monitoring system. Tight integration of your full-range speakers with your sub is key for critical accuracy during the recording, mixing, and mastering process. For Dynaudio, this involved assessing the acoustical characteristics of each of their popular high-end studio monitors and creating customized performance maps for each one. You select the specific Dynaudio speakers you are using from the 18S display’s menu, and the appropriate roll off will be applied automatically. The process is also future-proof: when Dynaudio adds new monitors to their range, 18S firmware updates that include the new speakers’ performance maps will be made available — so your monitoring system can grow according to your needs.

Flexible time- and phase-aligned integration into any studio setup

The 18S is fitted with a selection of RCA and XLR connections for flexible integration into your studio setup and includes a number of handy features to assist with integration into more advanced systems. This includes your ability to set a time delay to ensure the subwoofer and main speakers are working in perfect synchronicity. Simply enter the distance from the sub to the speakers, and the 18S automatically adjusts itself using time and phase delays. Also onboard is a three-way parametric equalizer to defeat room modes that could adversely affect the accuracy of your recordings.

Dual-opposing driver design for power and punch

In the 18S, two new drivers reside at either end of the cabinet, which is wider than it is deep for placement convenience. Delivering a powerful one-two punch is a pair of Dynaudio’s cutting-edge MSP+ Hybrid Drive units in a dual-opposing configuration, powered by a 500-watt Class D amplifier.

Hear every nuance and produce mixes that translate

For for the 18S, Dynaudio designed a brand-new driver they call the MSP+ Hybrid Drive. It’s made from aluminum rather than the company’s usual magnesium silicate polymer. It’s effectively a sandwich, with paper backing and an MSP dust-cap on the front. In recent years, the efficacy of sandwich construction has proven its worth for subwoofers, which typically require a more critical balance between stiffness, lightness, and damping than standard speaker drivers. Aside from the technology under the hood, Sweetwater can confirm that the 18S’s performance is exemplary. It’s a sub that integrates seamlessly with your Dynaudio monitors and lets you work with unfettered creative freedom, confident that you’re hearing every nuance — and that your mixes will translate to any playback system.

One of the standout features of the 18 S Dual 9.5 is its dual 9.5-inch drivers constructed with Magnesium Silicate Polymer (MSP) hybrid cones. This advanced driver technology provides exceptional rigidity and low distortion, translating to clean and precise bass reproduction. For the user, this means that the subwoofer can handle intense bass passages without coloration or muddiness, offering a true representation of your audio content. The hybrid cones also contribute to improved transient response, so even the fastest bass notes come through with clarity and impact.

Powered by a robust 500-watt amplifier, the 18 S delivers ample power to fill your studio space with consistent and dynamic low frequencies. This level of power ensures that the subwoofer can achieve a maximum peak sound pressure level of 110 dB at one meter, which is sufficient for professional monitoring environments of varying sizes. The wide frequency response range from 16 Hz to 230 Hz (±3 dB) means that it covers the entire bass spectrum, allowing you to hear sub-bass frequencies that smaller monitors might miss. This capability is crucial for genres that rely heavily on low-end detail, such as electronic music, hip-hop, and film soundtracks.

The subwoofer offers flexible connectivity options including two XLR inputs and outputs for left and right channels, along with dual RCA stereo inputs and outputs. This variety of connections ensures compatibility with a broad range of studio equipment and audio interfaces, making integration into your existing setup straightforward. Additionally, a 1/8-inch trigger input allows for automatic on/off functionality, which helps streamline workflow by powering the subwoofer in sync with your main monitors. The inclusion of a USB Type A service port ensures easy firmware updates, keeping your system up to date with the latest features and performance enhancements.
