Experience exceptional sound with BeoLab 3
This compact yet powerful speaker comes with a wall mount.
 
The BeoLab 3 is a high-performance, compact loudspeaker, distinguished by its ability to produce rich sound far exceeding its small dimensions. It relies on advanced engineering principles to achieve its acoustic goals.
Here is a description of its features and technology, avoiding proprietary text where possible:
 
🔊 Core Acoustic Innovation
 
Active Loudspeaker Design: The speaker is fully active, meaning it incorporates dedicated amplification for its drivers directly within the enclosure.
High-Efficiency Power Modules (ICEpower): It utilizes two powerful, highly efficient, and compact Class D amplifier modules—typically 125 Watts each for the bass and treble sections. This technology minimizes wasted energy as heat, allowing for the high-power modules to be fitted into the small cabinet without large heat sinks.
Controlled High-Frequency Dispersion (Acoustic Lens): The unique elliptical element at the top is a lens designed to disperse the high-frequency sound (treble) across a 180-degree horizontal arc. This wider, uniform sound field improves the listening experience in various seating positions and significantly reduces unwanted reflections off the floor and ceiling.
Bass Performance Management (ABL): It employs a sophisticated system of bass equalization that constantly adapts the low-frequency output to prevent over-excursion of the woofer. This allows the small driver to achieve deeper, louder bass tones than its physical size would normally permit, without causing distortion or damage.
 
📐 Physical and Technical Details
 
Double Radiator System: To produce strong low-end frequencies from a compact volume (around 1.5 liters), the speaker uses one main bass driver in conjunction with two passive radiators (sometimes referred to as drone cones). These work together to reinforce the bass output without the need for a traditional bass port.
Connectivity: The speaker is designed to receive both audio and control signals through a single type of multi-pin cable connection, though adapters can be used for standard line-level audio sources.
Placement Flexibility: It features a manual switch on the base that allows the user to optimize the sound equalization based on its placement in the room: Free Standing, Against Wall, or In Corner.
Components: It features a 19 mm tweeter and a 101.6 mm (4-inch) woofer, complemented by two identically sized passive radiators.
 
The speaker was originally introduced around 2004 and was conceived by designer David Lewis. It remains a notable example of miniaturized, high-fidelity audio engineering.
