Bang & Olufsen Beolab Penta

Details

BeoLab Penta speakers emerged from a revolutionary acoustic principle, blending extraordinary design with unparalleled sound quality. Thanks to its innovative pentagonal cabinet, the design minimized internal standing waves and reflections, effectively reducing distortion. The cabinet’s unique construction, featuring a moulded inner structure and stainless steel exterior, created the ideal environment for the loudspeakers to deliver optimal sound performance.

No matter the size of your room or the layout of your furniture, BeoLab Penta consistently produced remarkable sound. Moreover, it required minimal floor space and only needed ample headroom to fit seamlessly into your space.

The Evolution of BeoLab Penta

Bang & Olufsen introduced the BeoLab Penta in the late 1980s as their flagship speaker, and it evolved through several upgrades over the 1990s. Interestingly, the Penta I and Penta II featured an orange display, while the Penta III introduced a vibrant green display. Initially, there was a passive Beovox Penta version available. However, as time progressed, Bang & Olufsen focused exclusively on active loudspeakers, discontinuing models like the Beovox 4500.

Why Active Speakers?

Why build amplifiers directly into the loudspeakers? The answer lies in the ability to achieve a more compact design. This approach reduced the cabinet size to just one-third of a conventional speaker while maintaining the same powerful output. This method, known as Active Loudspeakers, allows the speaker to produce high volume without distortion. Furthermore, the amplifier, treble, and bass units work together, compensating for each other’s weaknesses and delivering music that replicates the original performance. As a result, you hear the music exactly as it was intended.

The Acoustic Excellence of BeoLab Penta

BeoLab Penta features nine individual loudspeaker units, strategically placed in a vertical alignment. This arrangement ensures exceptional sound dispersion and eliminates reflections from the floor and ceiling. Consequently, you can place BeoLab Penta almost anywhere in the room without compromising sound quality. In addition, the operating panel at the base allows users to fine-tune the bass reproduction across three settings.

The pentagonal cross-section of the cabinet eliminates standing waves, a common issue in traditional speakers. Moreover, Bang & Olufsen used polished stainless steel to help the speakers blend seamlessly into their surroundings. The reflective surface mimics the room’s color, giving the speaker a subtle, artistic appearance.

Sound Quality That Shines

The design of BeoLab Penta ensures that sound waves travel without interference from floor or ceiling reflections. As a result, BeoLab Penta produces an extraordinary acoustic experience. In fact, the sound quality is so clear and dynamic that it redefines how music should sound in any room.

The BeoLab 150: Controlled Power

At the heart of BeoLab Penta sits the BeoLab 150 amplifier, which delivers 175 watts of power (DIN/IEC). This power boosts both sound quality and volume, making it perfect for those who love high-energy music. Additionally, the amplifier includes a Dynamic Soft Clipping system, which prevents distortion during high-volume play. The system gently rounds off any overloading, ensuring the sound remains pure.

A Perfect Match for Bang & Olufsen Systems

To experience premium sound, your speakers need to match the quality of your system. BeoLab pairs perfectly with Bang & Olufsen’s Beosystem 5000 and Beocenter 9000, both featuring built-in CD players. These systems required equally exceptional speakers, and BeoLab Penta more than met the challenge. Moreover, the light display on the column base indicated the active music source. For seamless integration, Beolink® allowed you to enjoy music throughout your home, further enhancing the listening experience.
