Our Review

MartinLogan Dynamo Outdoor Passive Subwoofer Review


The realm of outdoor audio is a challenging environment for electronics. Extreme temperatures, moisture, and the need for non-intrusive aesthetics make designing for this space a specialized endeavor. MartinLogan, a brand revered for its audiophile-grade speakers, brings its expertise to the table with the Dynamo Outdoor Passive Subwoofer. Known for their electrostatic speaker line, MartinLogan has carved out a niche for high-fidelity sound with a focus on design and innovation.

Design and Build Quality


The visual design of the Dynamo Outdoor Subwoofer is subtle yet sophisticated, intended to blend seamlessly into a variety of outdoor landscapes. Its barrel-like shape and neutral color palette allow it to integrate without distracting from the natural beauty of its surroundings.

Materials and Construction

Constructed with fade-resistant thermoplastic, the subwoofer promises longevity even in harsh outdoor conditions. Its rugged build is designed to withstand the elements, indicating that MartinLogan has not compromised on the materials to ensure durability.


True to its claims, the Dynamo is completely weather- and waterproof. The sealed enclosure ensures that the internal components are protected from moisture, making it an ideal choice for poolside placements or open gardens. This level of weatherproofing is paramount for any outdoor audio equipment worth its salt.


Exclusive MartinLogan Technology

Leveraging its proprietary speaker technology, MartinLogan provides a sound that is often associated with indoor luxury audio systems. The inclusion of a 10-inch mineral-filled poly cone and a high-power voice coil indicates that the subwoofer is designed to deliver deep, musical bass with precision.

Compatibility with Amplifiers

The Dynamo's compatibility with a wide range of amplifiers, rated from 4 to 8 ohms, is a testament to its flexibility. This allows users to integrate the subwoofer into existing systems with ease or select an amplifier that suits their preferences without being limited by compatibility issues.

Mounting and Placement Options

The subwoofer's design allows for a variety of mounting and placement options, offering the user the freedom to optimize sound performance based on the specific layout of their outdoor space.


Sound Quality

The sound quality of the Dynamo Outdoor Subwoofer is where MartinLogan's reputation for high-fidelity audio becomes evident. The bass is rich and deep, adding an immersive dimension to outdoor listening experiences. The flared port system contributes to this by minimizing port noise and enhancing the overall musicality of the bass response.

Frequency Response

With a frequency response of 33–135Hz ±3dB, the subwoofer covers the lower spectrum of sound adequately, ensuring that bass lines are felt as much as they are heard. This range is suitable for a variety of music genres and can even enhance the experience of outdoor movie viewing.

Power Handling

The subwoofer's recommended amplifier power of 20—800 watts per channel gives users a broad range to find the perfect balance between volume and clarity. The sensitivity ratings, 88 dB in-room and 82 dB anechoic, indicate a subwoofer that is efficient in its power usage while still being capable of delivering substantial output.

Installation and Setup

Ease of Installation

The Dynamo Outdoor Subwoofer is designed to be user-friendly when it comes to installation. The various mounting options allow for a straightforward setup process, although the need for an external amplifier could add complexity for those not already equipped with one.

Required Accessories

Since it is a passive subwoofer, an external amplifier, such as the recommended Crown CDi 1000, is necessary. Speaker wire is also required for connection, and users should ensure that they use weatherproof wire for outdoor installations.

Use Cases

The subwoofer is ideal for those looking to enrich their outdoor audio experience, whether it be for ambient music in a commercial setting like a restaurant patio or for the homeowner who wants to add depth to their backyard sound system.

Value Proposition

Priced at $1,799.99 each, the MartinLogan Dynamo Outdoor Subwoofer sits at a premium price point. However, its robust construction, high-quality sound, and flexibility justify the cost for those who prioritize audio performance and durability in challenging outdoor environments.

Pros and Cons Recap

- All-weather and waterproof construction suitable for outdoor use
- Exclusive MartinLogan speaker technology for high-quality sound
- Scalable system design for flexibility in expansion
- Flared port system and high-quality transducer for deep, musical bass
- Compatible with a wide range of amplifiers

Final Thoughts

The MartinLogan Dynamo Outdoor Passive Subwoofer is a robust, high-performance audio solution for outdoor spaces. Its meticulously crafted design, coupled with MartinLogan's proprietary technology, delivers a sound quality that enhances any outdoor audio system. While the need for an external amplifier may be a consideration for some, the flexibility and depth of performance it offers make it a compelling choice for audiophiles looking to extend their high-fidelity experience to the outdoors.
