Beolab 3 Active Speakers ICE amplification technology (Pair)

The Bang & Olufsen BeoLab 3 is a compact active loudspeaker that challenges conventional expectations of small speakers. Designed as a high-performance successor to earlier lifestyle models, it combines advanced acoustic engineering with distinctive sculptural design. Despite its modest size, the BeoLab 3 was engineered to deliver large-scale sound, precise imaging, and room-filling performance, making it one of B&O’s most technically ambitious compact speakers.

At its core, the BeoLab 3 integrates amplification, digital processing, and acoustic dispersion technology into a fully optimised system, removing the traditional guesswork of amplifier matching and speaker placement.

🏗 Design & Engineering Philosophy

The BeoLab 3 was created to solve a fundamental problem: how to achieve true hi-fi dispersion and scale from a small speaker.

Key engineering principles:

• Acoustic Lens distributes treble evenly across 180° horizontally

• Eliminates narrow “sweet spot”

• Active amplification precisely tuned to each driver

• High-power DSP manages bass extension without distortion

• Rigid enclosure minimises cabinet coloration

The result is a speaker that behaves far larger than its physical footprint.

🎧 Sound Performance

Tonal Balance

• Neutral and clean tonal presentation

• Exceptionally transparent midrange

• Smooth, highly detailed treble without harshness

• Bass surprisingly deep and controlled for size

Imaging & Soundstage

• Outstanding spatial dispersion

• Wide listening area with consistent tonal balance

• Stable imaging even off-axis

• Creates an immersive, room-filling sound field

Dynamics

• Fast transient response

• Strong micro-detail retrieval

• Maintains clarity at higher volumes

• Feels energetic yet refined

Real Listening Character

The BeoLab 3 delivers sound that feels effortless and expansive, avoiding the boxy or constrained character typical of compact speakers. Music floats freely into the room rather than appearing confined to speaker locations.
