Triangle Borea BR04 black (pack of 2)

The Triangle BR04 embodies the new generation of bookshelf speakers in the Borea range from the French manufacturer. It represents an evolution of the BR03, with notable improvements in acoustic performance while maintaining a compact format. Featuring a redesigned front-firing bass-reflex port, dual binding posts suitable for audiophile setups, and a proprietary vibration reduction system, the BR04 continues a tradition of technical mastery. Designed for rooms from 10 to 40 m², it combines sonic precision, present bass, and excellent vocal intelligibility.

Refined Design and Elegant Finishes

The BR04 follows the aesthetic lineage of the Borea range with a design that is both modern and timeless. Its cabinet, with carefully calculated dimensions (220 x 425 x 314 mm), houses advanced acoustic technology while maintaining a discreet elegance that blends harmoniously into any interior.

Triangle offers a remarkable choice of six distinct finishes for these speakers: black, white, chestnut, light oak, light blue oak, and green oak. This variety allows the BR04 to adapt to all decorative styles, from the most classic to the most contemporary. The wood finishes add a warm and authentic touch, while the black and white versions fit perfectly into minimalist interiors.

The protective fabric grilles, attached by an ingenious magnetic system, can be easily removed to admire the drivers or replaced to protect them. This screwless system preserves the purity of the lines while ensuring effective protection for the transducers.

At the base of the speaker, new rubber feet serve a dual purpose: they effectively absorb vibrations generated by the speaker and ensure perfect stability on any type of surface. This attention to detail reflects Triangle’s care in every aspect of the design.

Technical Innovations Serving Musicality

The BR04 incorporates several technical advances that set it apart in its category. At the heart of these innovations is the new front-firing bass-reflex port, the result of extensive research into airflow optimization. This design significantly improves air circulation inside the speaker, delivering deeper and better-controlled bass while reducing acoustic turbulence.

The front placement of the port is also a major practical advantage: unlike traditional rear ports, this configuration allows the speakers to be placed close to a wall without compromising sound quality. This placement flexibility is invaluable in tight spaces or when room layout imposes constraints.

The DVAS (Driver Vibration Absorption System), exclusive to Triangle, is another notable innovation. This system cleverly integrates the drivers into the speaker structure to reduce unwanted vibrations. By improving overall rigidity and attenuating undesirable frequencies, DVAS contributes to a clearer, more detailed, and more dynamic sound reproduction.

The internal architecture of the BR04 has been completely redesigned compared to the BR03. The increased cabinet volume extends the low-frequency response, while the reinforced structure limits unwanted resonances. These structural optimizations, though invisible, play a decisive role in the overall sound quality.

High-Precision Drivers

The BR04 is equipped with a 25 mm silk dome tweeter featuring Triangle’s EFS (Efficient Flow System) technology. This system combines the dome with a specially designed waveguide to ensure even dispersion of high frequencies throughout the listening room. This design guarantees a precise and stable stereo image, with detailed treble reproduction free from harshness.

For the midrange and bass, Triangle has chosen a 16 cm driver with a natural cellulose pulp cone. This material, selected for its outstanding acoustic properties, gives voices remarkable warmth and naturalness. The cone profile has been specifically reworked for the BR04 to reduce distortion during large excursions, allowing for clear and defined listening even at high volumes.

The combination of these two high-quality drivers, optimized by carefully calculated crossover filtering, enables the BR04 to deliver exceptional tonal coherence across the entire audible spectrum. The transition between registers is smooth and natural, without artificial coloration.

Sound Performance

With an extended frequency response from 44 Hz to 22 kHz, the BR04 delivers remarkably balanced sound reproduction. The low frequencies are rendered with depth and precision, without the booming effect sometimes found in compact speakers. This bass extension allows you to fully appreciate low-frequency instruments such as double basses or kick drums, with striking realism.

The high sensitivity of 90 dB/W is a major asset for these speakers. This feature allows them to deliver significant sound levels even with modestly powered amplifiers, while preserving dynamics and detail finesse. The BR04 is thus compatible with a wide range of electronics, from low-powered tube amplifiers to more powerful solid-state models.

One of the most remarkable qualities of the BR04 lies in its exceptional vocal timbre reproduction. Thanks to its cellulose pulp mid-bass driver, it renders voices with striking warmth and naturalness. This makes it particularly well-suited for vocal music lovers, from jazz to opera to chanson.

The soundstage produced by the BR04 impresses with its width and depth. Instruments are precisely positioned in space, creating a three-dimensional stereo image that transcends the physical dimensions of the speakers. This ability to “disappear” acoustically in favor of the music is a testament to the quality of these speakers’ design.

Outstanding Versatility

The BR04 stands out for its exceptional versatility. In a traditional stereo setup, it excels at reproducing all musical genres, from classical works to contemporary electronic productions. Its ability to faithfully render dynamic nuances and instrumental timbres makes it an ideal partner for discerning music lovers.

In a home theater system, the BR04 also demonstrates remarkable qualities. Used as front channels, it ensures precise reproduction of dialogue and sound effects, with perfect coherence between image and sound. As rear or surround channels, it helps create an immersive and realistic sound environment.

Compatibility with all ten models in the Borea range allows for a homogeneous and coherent multichannel system. Whether paired with the BRC1 and BRC2 center speakers, the BRS1 effect speakers, or the floorstanding models in the series, the BR04 integrates perfectly into a complete surround setup.

Thanks to its front-firing bass-reflex port, the BR04 adapts to various installation configurations. It can be placed on a shelf, furniture, or dedicated stands, even close to a wall, without compromising its acoustic performance. This positioning flexibility is a significant advantage over rear-ported models, which require more clearance.

Audiophile Configuration

The BR04 features dual binding posts, a feature usually reserved for high-end models. This configuration allows the speakers to be used in bi-wiring (using two pairs of cables from the same amplifier) or bi-amping (using two separate amplifiers for bass and treble).

The crossover design has been completely rethought to fully exploit this advanced connectivity. The processing of mid-bass frequencies is now separated from that of the high frequencies, allowing for more precise and faithful sound reproduction. This approach ensures better transient definition and clearer instrument separation.

For audiophiles seeking sonic perfection, the ability to bi-amp the BR04 opens up exciting possibilities. By dedicating one amplifier to the bass and another to the treble, it becomes possible to optimize the reproduction of each register and achieve even higher listening quality. This scalability is a major asset for these speakers, which can accompany the listener as their system evolves.

The binding posts themselves are of high quality, with gold-plated contacts ensuring optimal connection with speaker cables. They accept all common terminations (banana plugs, spades, or bare wire), offering great connection flexibility.

Frequently Asked Questions

What is the main difference between the BR04 and the BR03? The BR04 stands out with several significant improvements: a larger cabinet volume for deeper bass, a front-firing bass-reflex port for more flexible placement, dual binding posts allowing for bi-wiring and bi-amping, and an optimized mid-bass cone profile to reduce distortion at high volumes. These technical advances result in superior sound quality, especially in the low frequencies.

What type of amplifier is recommended for the BR04?
