Triangle Borea BR04

The BR04 Was Crafted to Enhance the BR03, Offering Superior Performance While Maintaining a Compact, Affordable Design

• High-fidelity passive bookshelf speaker pair
• EFS silk-dome tweeter and cellulose pulp midrange/bass driver
• Redesigned front bass-reflex port and expanded cabinet for optimized airflow
• Delivers clear vocals and natural warmth

Borea BR04

The BR04 integrates the EFS silk-dome tweeter and a cellulose pulp midrange/bass driver, ensuring clear vocals and natural warmth. The elegant design is available in six finishes, offering the flexibility to fit in any décor.

Additional improvements include a redesigned front bass-reflex port and an expanded cabinet, optimizing airflow for deeper, more controlled bass. The addition of double binding posts, combined with an upgraded crossover, enables bi-wiring and bi-amplification for enhanced sound precision.

With a frequency range from 44 to 22,000 Hz and a sensitivity of 90 dB, the BR04 is perfect for rooms from 10 to 40 m2. It offers rich, detailed sound for both Hi- Fi and home theater setups, ensuring a versatile and immersive listening experience.

High-Performance Loudspeakers

The BR04 is a two-way bookshelf loudspeaker that can be placed on a dedicated stand or placed on a bookshelf or counter. The 25mm silk dome tweeter combined with a waveguide (EFS Technology) ensures precise sound and even sound diffusion.

The 16cm-diameter bass-midrange with a natural cellulose pulp membrane for a warm, realistic reproduction of vocal timbre. The cone profile has been reworked to reduce distortion at high frequencies, for a clearer sound at high volumes. The new Borea BR04 is perfect for rooms ranging from 10 to 40m², delivering rich, detailed sound.

DVAS System

Triangle's exclusive DVAS (Driver Vibration Absorption System) reduces vibrations by cleverly integrating the drivers into the speaker structure. This improves the rigidity of the whole to attenuate any parasitic frequencies. This process attenuates vibrations generated by the movement of the midrange driver. The result: sound reproduction gains in clarity, detail and dynamics.

New Tubular Vent + Adapter Rubber Pads

The BR04 features a new bass-reflex port on the front, optimizing airflow for deep, controlled bass. This reduces turbulence and delivers more accurate sound reproduction. The larger cabinet size extends the frequency response in the bass range from 44 to 22,000 Hz, with a sensitivity of 90db/W. The front port allows the BR04 speaker to be positioned with more flexibility even against a wall without compromising sound quality.

The new dual-function rubber pad system effectively dampens vibrations generated by the speaker and reduces unwanted resonances, ensuring greater acoustic clarity. Its ingenious design holds the speaker firmly to your stand, preventing any slippage or imbalance.

Double Binding Post

The BR04 employs new double binding posts with a redesigned crossover architecture, separating mid-bass frequency processing from high frequencies. This configuration allows the speakers to be used in bi-wiring and bi-amplification. 

This approach guarantees more accurate and faithful sound reproduction. Ideal for audiophiles in search of the finest detail, it offers a sound experience of exceptional purity and precision.

Hi-Fi and Home Theatre

The BR04 stands out for its high fidelity reproduction of the timbre of the human voice, thanks to its cellulose pulp driver that offers real intensity to all vocal performances. It is ideal for both a stereo Hi-Fi installation and a home cinema system. Whether front or rear channel, the BR04 will give you an immersive audio-visual experience.
