TRIANGLE Borea BR04 Bookshelf Speakers
The TRIANGLE Borea BR04 Bookshelf Speakers were crafted to enhance the BR03, offering superior performance while maintaining a compact, affordable design.
The update provides upgraded performance, especially in the bass, while retaining the qualities that made the BOREA range successful.
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 theatre setups, ensuring a versatile and immersive listening experience.

PUSH THE LIMITES OF THE BR03
The BR04 was born of the desire to push the limits of the famous BR03, offering even better performance in a compact bookshelf speaker. With the BR04 TRIANGLE is continuing the tradition of offering affordable high performance in the BOREA speaker range.
The BR04 benefits from several improvements that enhance low-frequency sound reproduction, while gaining clarity.
COMPACT, 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.
NEW TUBULAR VENT
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
HI-FI & HOME THEATRE
TRIANGLE now offers 10 models in the BOREA range offering an affordable high performance for both Two Chanel and Home Theater. 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.
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.
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.
VINTAGE AND MODERN FINISHES
The new bookshelf loudspeaker is inspired by the aesthetics of the BOREA range, combining elegance, authenticity and a return to natural materials. It is distinguished by six unique finishes: Black, Chestnut, Light Oak, Oak Green, Light Oak Blue and White, allowing it to blend perfectly with any interior style.
Fabric grilles with magnetic fastenings add a touch of refinement while protecting the loudspeakers, combining meticulous design and functionality.
IMPROVED SET-UP – ADAPTED RUBBERS PADS FOR STANDS
The BR04 loudspeaker features a new dual-function rubber pad system:
- it effectively dampens vibrations generated by the speaker and reduces unwanted resonances, ensuring greater acoustic clarity.
- its ingenious design holds the speaker firmly to your speaker stand, whatever model you choose.
This added stability prevents any slippage or imbalance, guaranteeing an optimal experience.

Amplifier and Power Handling
- Recommended amplifier RMS power: 25 to 130 watts (8 Ohms).
- Power Handling : 110 Watts
* The power handling of a speaker is the average continuous power that the speaker can accept without damaging the drivers. You can use an amplifier more powerful than the permissible speaker power by limiting the volume to 70% of the maximum capacity. Conversely, an amplifier that is too underpowered will clip and create distortion, which can also damage the speakers if it is used beyond its capacity.
Features
Speaker Specifications
- Type: Bass Reflex Bookshelf with front bass reflex port
- Crossover: 2 Ways
- Sensitivity: 90 dB
- Bandwidth (+/- 3dB): 44 – 22,000 Hz
- Nominal impedance: 8Ω
- Minimum impedance: 4.6 Ω
* The impedance of a speaker can be simplified as an electrical resistance. The lower is the impedance of the speaker, the more current the amplifier will have to deliver.
- Nominal impedance is measured at a frequency of 1kHz
- Minimum impedance is measured at low frequencies.
TRIANGLE loudspeakers never fall below 3 Ohms, which means they can be used with almost all Hi-Fi and Home Cinema amplifiers.
