The Triangle Borea BR09 Walnut is the flagship floor-standing speaker of the Borea range, designed to deliver a high-end audio experience at an affordable price. Combining advanced technologies with elegant design, this 3-way speaker promises exceptional sound performance for music and home theater enthusiasts.
A commanding column with sleek lines
The Borea BR09 stands out with its design that is both imposing and elegant. Standing at 1.095 meters tall, this floor-standing speaker makes a striking impression in any room. Its walnut-finished cabinet adds a warm and sophisticated touch that blends seamlessly into contemporary interiors.
The clean front panel is adorned with five symmetrically arranged drivers: a central tweeter, a midrange, and three woofers. The white surrounds of the drivers create a subtle contrast with the wood, while the removable magnetic grille allows you to conceal the drivers for a more discreet look if desired.
A high-end acoustic configuration
At the heart of the BR09 lies a sophisticated 3-way configuration, a testament to Triangle’s acoustic expertise. The 25 mm silk dome tweeter features the brand’s EFS (Efficient Flow System) technology. This system optimizes the dispersion of high frequencies throughout the room, delivering a wide and immersive soundstage.
The 16 cm midrange driver uses a natural cellulose membrane, a material prized for its neutrality and ability to faithfully reproduce vocals. The three 16 cm woofers are equipped with fiberglass membranes, combining rigidity and lightness for deep and impactful bass.
This configuration enables the BR09 to cover a wide frequency range, from deep bass at 35 Hz to crystal-clear highs at 22 kHz. Its high sensitivity of 92.5 dB and nominal impedance of 8 Ω make it easy to drive with an amplifier.
Innovative technologies for superior sound
Triangle has equipped the BR09 with several technological innovations to optimize its performance. The DVAS (Driver Vibration Absorption System) uses perforated MDF panels and EVA foam to reduce unwanted vibrations and enhance sound precision.
The large front-facing bass-reflex port extends low-frequency response while minimizing compression. The sophisticated crossover ensures smooth transitions between the drivers for optimal sonic coherence across the entire spectrum.
Breathtaking sound reproduction
Thanks to its meticulous design, the BR09 delivers a captivating listening experience. Vocals are reproduced with striking naturalness, rich in nuances and presence. Acoustic instruments benefit from excellent tonal balance, with accurate timbres and a beautiful sense of space.
In the bass range, the three woofers deliver deep and articulate lows, capable of reproducing the physical impact of a kick drum or the vibrations of an organ. The impressive dynamics allow the speaker to handle delicate passages and intense fortes without audible compression.
The wide and deep soundstage immerses the listener in the heart of the music. Whether for stereo listening or a home theater setup, the BR09 offers an immersive and emotional experience.
Remarkable versatility
While designed to excel in large rooms over 30 m², the BR09 adapts well to smaller spaces thanks to its well-controlled bass. It is equally suited for music listening and movie watching, providing balanced and dynamic performance in both cases.
Its high sensitivity allows it to be driven by moderately powered amplifiers, while also handling high power levels for demanding passages. This versatility makes it an excellent choice for gradually building a high-end system.

I wanted to pair my Advance Paris amplifier with speakers made in France. After numerous discussions with the sales staff at the Compiègne store, I chose this pair of Triangle speakers. First of all, I must say that they are of excellent build quality; they are solid and imposing floorstanding speakers. But they are also magnificent, especially in this oak finish, and without the protective grille, I can say that they leave no one indifferent. In terms of sound, paired with Triangle cables, after several hours of listening, they give my amplifier a second life. At low or slightly higher volume, they reveal the slightest note, are well balanced, and go deep into the bass without ever overwhelming the space or tiring the listener over time. And I know that this investment will allow me to consider an even more powerful amplifier later on. In short, thanks to the Compiègne store, which once again knew how to meet my expectations. My ears thank you!!

J'ai voulu associer mon amplis advance paris avec des enceintes fabriquées en France.
Apres de nombreux échanges avec les vendeurs du magasin de Compiègne, j'ai opté pour cette paire de Triangle.
D'abord je dois dire qu'elles sont d'excellente qualité de fabrication, ce sont de solides et imposantes colonnes. Mais elles sont également magnifiques, notamment avec cette couleur chêne, et sans la grille de protection, je peux affirmer qu'elles ne laissent personne indifférent.
Au niveau du son, associées à des câbles triangle, après plusieurs heures d'écoute, elles donnent une seconde vie à mon ampli.
A faible ou volume un peu plus élevé, elles révèlent la moindre note, bien équilibrée et descend bien dans les graves sans jamais saturer l'espace ni fatiguer l'auditeur à la longue.
Et je sais que cet investissement me permettra d'envisager plus tard un ampli encore plus performant.
Bref, merci au magasin de Compiègne qui une nouvelle fois a su répondre à mes attentes.
Mes oreilles vous remercient!!

Replaced my Antal 202 and I really don’t regret it at all: precision, clarity, and a big soundstage with good bass. On top of that, they look gorgeous without being much bulkier.

Remplacement de mes antal 202 et vraiment je ne regrette pas du tout, précision , netteté et grande image sonore avec les bonnes basses. En plus elles sont magnifiques sans êtres beaucoup plus volumineuses.
