BeoLab 3 was designed as a compact and high-quality loudspeaker, and it quickly became one of the most popular choices in Bang & Olufsen’s range of smaller speakers. Its sleek aluminium cabinet houses two drive units: a 4.5” woofer and a 0.75” tweeter. Additionally, it features two passive bass radiators, also known as “drone cones.” These radiators enhance bass response by functioning similarly to tuned ports in a bass-reflex system.
As an active speaker, the BeoLab 3 incorporates two Class “D” amplifiers, each rated at 125W. Although the catalogues don’t specify what 125W into a 0.75” tweeter sounds like in a home setting, the BeoLab 3’s design clearly demonstrates B&O’s commitment to performance. The tweeter’s sound dispersion benefits from an acoustic lens, which provides an alternative to the typical method of directly facing the driver toward the listener. This approach, in fact, mirrors a concept that Canon abandoned in the early 1990s, a company better known for its cameras and photocopiers.
Stylistically, the BeoLab 3 draws heavily from the Beovox 2500 ‘cube’ of 1967. As a result, the similarities are especially noticeable when the speaker is placed on its small table stand, particularly in the black version. By evoking the Beovox 2500, B&O seems to question whether its best years had passed when they designed the BeoLab 3.
The Beovox 2500 was not a full loudspeaker; rather, it served as an auxiliary treble radiator. This component was necessary to compensate for the limited treble dispersion of cone tweeters at the time. However, as dome tweeters became the standard, this design quickly became obsolete. To retain the Beovox 2500’s look while maintaining functional acoustics, the BeoLab 3 introduced two passive bass radiators. These radiators effectively mimic the original model’s circular grilles.
Passive bass radiators—also known as Auxiliary Bass Radiators or “drone cones”—have appeared sporadically throughout B&O’s history. For example, the Beovox 5700 from the early 1970s, as well as the RL 45 and RL 60 from the 1980s, featured these components. However, B&O later replaced passive radiators with conventional bass ports, as seen in the RL 45.2 and RL 60.2. This shift suggests that passive radiators were not always ideal from an acoustic perspective.
Despite these considerations, the BeoLab remains an attractive and well-crafted speaker. Not only does it deliver satisfying sound for most listeners, but it also offers versatility in placement. With a wide range of stands and mounting options, the BeoLab 3 can fit seamlessly into any room. Whether you want it to make a bold statement or blend into the background, it adapts to your preference. While a conventional vented cabinet may have produced better performance, B&O’s target audience clearly prioritized design alongside sound quality. Ultimately, the BeoLab 3 proves that form and function can indeed coexist.
