The AM1 from Bowers & Wilkins brings certain technologies from studio monitors into a format designed for outdoor use. This two-way speaker stands out with its inverted driver configuration and the integration of a passive radiator, all while maintaining a waterproof design suitable for outdoor conditions.
Unlike many outdoor speakers that prioritize durability at the expense of sound quality, the AM1 aims to balance audio fidelity and weather resistance, notably incorporating elements from the brand’s hi-fi ranges, such as Nautilus technology and the anti-resonance plug.
Technical Design and Acoustic Innovations
The AM1 is distinguished by its inverted driver configuration, a counterintuitive approach that places the aluminum dome tweeter below the mid/bass driver. Far from being a mere detail, this arrangement optimizes sound dispersion when the speaker is mounted high under an eave or in an attic. The 25 mm tweeter benefits from Nautilus tube loading, a technology inherited from B&W’s legendary studio monitors that absorbs unwanted resonances at the rear of the driver.
The 130 mm mid/bass driver with a fiberglass cone features the anti-resonance plug developed for the PM1 speaker. This mushroom-shaped device, made from polymer foam, absorbs internal resonances and reduces cone breakup, delivering exceptional midrange clarity. Typically reserved for high-end hi-fi speakers, this technology finds a unique outdoor application here.
The major innovation lies in the ABR (Auxiliary Bass Radiator) passive radiator mounted at the rear of the speaker. Unlike traditional bass-reflex ports that compromise waterproofing, this system uses a passive membrane that vibrates in resonance with the main driver to extend the bass response. This solution achieves a low cutoff frequency of 51 Hz while maintaining perfect enclosure sealing.
Extreme Resistance and Durability
The AM1 undergoes a rigorous battery of tests that far exceed the usual standards for outdoor speakers. Each speaker is subjected to an accelerated salt spray chamber simulating decades of exposure to sea air. Prolonged UV exposure tests ensure the stability of materials and finishes against the most intense sunlight.
The ultra-rigid enclosure, made from glass fiber-reinforced plastic, resists impacts, extreme temperature variations, and deformation. The anodized aluminum front grille with anti-corrosion treatment retains its like-new appearance even after years of exposure. This construction allows for permanent outdoor use, including in particularly harsh environments such as poolside areas or coastal zones.
The enclosure’s total waterproofing protects the internal electronics from dust, humidity, and water splashes. This hermetic design even allows installation right next to a pool without risk of damage.
Versatile Installation and Easy Mounting
The AM1’s wall-mounting system perfectly illustrates Bowers & Wilkins’ pragmatic approach. The 220-degree swivel bracket allows precise orientation of the speaker according to the room’s acoustics. This wide rotation is especially useful for installations under eaves or in complex architectural corners.
The speaker can be installed either vertically or horizontally, depending on space constraints. This orientation flexibility, made possible by the inverted driver configuration, multiplies architectural integration options. The cable management system built into the bracket completely conceals wiring, preserving the installation’s aesthetics.
Despite its “outdoor” designation, the AM1 also excels indoors. Its robust construction and sleek design make it a relevant choice for public spaces, restaurants, or conservatories. This versatility sets the AM1 apart from classic outdoor speakers, which are usually limited to outdoor use only.
Sound Quality and Audiophile Heritage
The AM1 faithfully brings Bowers & Wilkins’ acoustic expertise to the outdoor world. Its extended frequency response and low harmonic distortion preserve musical nuances even in open air. The ABR passive radiator delivers surprisingly deep bass for a cabinet of this size, rivaling indoor speakers of equivalent dimensions.
The inverted driver configuration significantly improves sound dispersion when mounted high, eliminating the acoustic dead zones often found with conventional speakers. This even dispersion ensures balanced listening across a wide area, ideal for large outdoor spaces.
With a sensitivity of 86 dB and an impedance of 8 ohms, the AM1 pairs easily with most hi-fi amplifiers and home theater systems. Its 100-watt power handling allows for generous sound levels without dynamic compression.
Compatibility and System Integration
The AM1 naturally integrates into existing multiroom systems thanks to its traditional wired connectivity. Its passive design makes it compatible with all amplifiers on the market, from AV receivers to dedicated hi-fi amps. This universality makes it easy to incorporate into existing setups without special requirements.
The speaker can be paired with an outdoor subwoofer to create an exceptional 2.1 system. Its balanced frequency response also allows it to function as a satellite in more ambitious multichannel configurations.

I bought the Bowers & Wilkins AM-1 for outdoor use (terrace/garden), and I’m very satisfied with the result.
The sound quality is excellent for speakers of this size: clear, well-defined sound, with a nice presence in the mids and precise, non-aggressive highs. The sound remains balanced even at higher volumes, which is very appreciable outdoors. Obviously, the bass is limited by the size of the speakers, but it’s clean, consistent, and more than sufficient.
The design is very well executed: sturdy materials, high-end finish, and a real sense of durability. They’re advertised as weather-resistant, which seems credible given the build quality. The wall-mounting system is well thought-out, discreet, and allows for easy adjustment of the orientation.
These aren’t cheap speakers, but the price is justified by the audio quality, build, and reliability, especially if you’re looking for a durable and elegant outdoor solution.
In short: an excellent choice for anyone who wants quality sound outdoors, without compromising on design or robustness.

J’ai acheté les Bowers & Wilkins AM-1 pour une utilisation extérieure (terrasse/jardin), et je suis très satisfait du résultat.
La qualité sonore est excellente pour des enceintes de ce format : son clair, bien défini, avec une belle présence dans les médiums et des aigus précis, sans agressivité. Le rendu reste équilibré même à volume soutenu, ce qui est appréciable en extérieur. Évidemment, le grave est limité par la taille des enceintes, mais il est propre, cohérent et largement suffisant.
La conception est très soignée : matériaux solides, finition haut de gamme et vraie impression de durabilité. Elles sont annoncées comme résistantes aux intempéries, ce qui semble crédible au vu de la construction. Le système de fixation murale est bien pensé, discret et permet un réglage facile de l’orientation.
Ce ne sont pas des enceintes bon marché, mais le prix est justifié par la qualité audio, la fabrication et la fiabilité, surtout si l’on cherche une solution extérieure durable et élégante.
En résumé : un excellent choix pour qui veut un son de qualité en extérieur, sans compromis sur le design ni la robustesse.
