At the heart of the ES20 lies a finely-tuned 5.25” mid-bass driver, delivering bass that's both deep and tight, ensuring every beat is felt as much as it is heard. The 1” aluminum dome tweeter complements this by faithfully reproducing the sparkling highs of your music. These components work in harmony to provide a balanced audio experience, offering clear highs, rich lows, and everything in between.

Our Review

Cambridge Audio ES20 Outdoor Speaker Review


In the realm of outdoor audio, finding the right balance between durability, performance, and aesthetics can be quite the challenge. Cambridge Audio, a brand with a longstanding reputation for producing quality sound equipment, steps into this arena with the ES20 Outdoor Speaker. This review delves into how these speakers hold up against the elements and whether they can truly enhance your outdoor audio experience.

Design and Build Quality

The ES20 speakers boast a sleek, matte white finish, designed to blend seamlessly with your outdoor decor. The compact size belies a ported cabinet design that promises powerful bass output from a relatively small enclosure. The build quality is robust, engineered to endure the rigors of outdoor placement, including extreme temperatures and humidity levels.

Compact and Durable Construction

At just 5.5 lbs and with dimensions of H 10.7" x W 6.8" x D 6.5", the ES20 is both unobtrusive and portable. The materials selected for construction are clearly chosen with longevity in mind, ensuring that these speakers can survive prolonged exposure to harsh outdoor conditions.

Mounting and Placement Flexibility

Installation is made user-friendly with custom-designed mounting brackets that include cable routing for a clean setup. The adjustable swivel mount offers practical positioning, allowing users to direct sound precisely where it’s needed. This flexibility is invaluable in outdoor environments where acoustics can be unpredictable.


Weather Resistance

The ES20's ability to resist weather-related wear is commendable. Engineered to withstand both extreme humidity and temperature variations, these speakers are an ideal candidate for anyone looking to install a permanent outdoor audio solution.

Compatibility and Integration

Compatibility is a strong suit for the ES20. The inclusion of OmniMount bracket compatibility is a thoughtful touch, allowing for easy integration into existing setups. Furthermore, the ability to pair with a Sonos ZP120 makes these speakers a smart choice for users already invested in the Sonos ecosystem.


Sound Quality

The 5.25” mid-bass driver and 1” aluminium dome tweeter work in tandem to deliver a crisp and expressive sound. The frequency response of 65Hz – 20kHz is fairly typical for outdoor speakers, but the ES20 distinguishes itself with an impressive clarity that can fill large outdoor spaces effectively. However, while the ES20 performs admirably in clarity and sound dispersion, the bass response may not satisfy those looking for a deep, thumping bassline without the addition of a separate subwoofer.

Power and Efficiency

With a sensitivity rating of 88dB and an impedance that fluctuates between 4 and 8 ohms, the ES20 is efficient and flexible. It performs well with a wide range of amplifiers, from 10W to 100W. This versatility ensures that whether you’re looking for a soft background ambiance or a more vibrant soundstage, the ES20 can accommodate.

Practicality for Outdoor Use

The ES20 is designed with outdoor practicality in mind. Whether placed in a garden, on a patio, or a rooftop, these speakers prove to be a reliable audio source. The volume and sound quality are sufficient for personal enjoyment without becoming a nuisance to neighbors, which is an important consideration in residential areas.

Volume and Sound Dispersal

The ES20 manages volume and sound dispersal with aplomb. The speakers are loud enough to enjoy music during outdoor activities but calibrated to prevent sound from traveling too far. This careful balance ensures a good neighborly relationship while still providing a satisfying audio experience.

Comparison with Competitors

When compared to other outdoor speakers in its class, the ES20 holds its ground with its combination of sound quality, flexibility, and weather resistance. While some competitors may offer additional features like Bluetooth connectivity or a wider array of color options, the ES20's performance and compatibility features make it a strong contender in the market.

Pros and Cons Revisited

The weather resistance, sound quality, and compatibility features are clear advantages of the ES20. However, the lack of Bluetooth or Wi-Fi connectivity out of the box could be seen as a missed opportunity. The limited color options may also deter some customers looking for a more personalized touch. The bass performance, while adequate, may not meet the expectations of audiophiles or those seeking a more immersive low-end experience.

Final Thoughts

The Cambridge Audio ES20 Outdoor Speaker offers a compelling package for those seeking a durable, high-performing outdoor audio solution. Its design and build are tailored for the challenges of outdoor audio, and its sound quality is more than capable of providing a rich listening experience. While it may not boast the deepest bass or the widest array of features, its strengths in weather resistance, sound clarity, and integration options make it a worthy addition to any outdoor space. For those in search of a reliable, high-quality outdoor speaker system, the ES20 deserves serious consideration.
