BOREA BR04 BOOKSHELF SPEAKER

The new BR04 was crafted to enhance the BR03, offering superior performance while maintaining a compact, affordable design. These efforts provide, 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 theater setups, ensuring a versatile and immersive listening experience.

COMPACT, HIGH-PERFORMANCE LOUDSPEAKERS

Extended Frequency Response

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.

DOUBLE BINDING POST

For Audiophile Set-up

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.

ADAPTED RUBBERS PADS FOR STANDS

IMPROVED SET-UP

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.

Overall Score 90/100

Nicely Roasted

The Borea BR04 pairs a reworked 16cm cellulose midwoofer and 25mm silk-dome tweeter to deliver notably deeper, controlled low end and airy, detailed highs. Triangle's DVAS and front bass-reflex port sharpen imaging and reduce coloration, yielding natural mids and confident dynamics. Reviewers like Robert Silva praise its clarity and bass that outperforms peers in its class.

Best of High End

"Triangle has once again pushed the envelope in audio excellence with the introduction of the BOREA BR04 bookshelf speaker."

ecoustics

"The Triangle BOREA BR04 appear well positioned to deliver on all of those items and when you consider the performance of the previous iteration — these could be a sleeper product below $600 that provide long-term listening enjoyment."

Pros

Deep, controlled bass extension for its size thanks to the 16cm midwoofer and front bass-reflex port.
Warm, natural midrange and clear vocal timbre from the natural cellulose pulp driver and reworked cone profile.
Refined treble and even dispersion courtesy of the 25mm silk-dome tweeter with EFS waveguide.
Solid engineering (DVAS, revised crossover, double binding posts) that reduces vibration, supports strong dynamics and offers bi‑wire/bi‑amp flexibility.

Cons

Front-mounted bass reflex improves bass control but can reduce perceived soundstage depth and imaging unless placement/toe-in is optimised.

Sound Quality

90/100

Bass

91/100

16 cm mid-woofer + front bass-reflex port and larger cabinet give extended, controlled low end down to ~44 Hz. Multiple reviews praise deeper, more controlled bass versus the BR03; for its size the BR04 is notably robust.

Mid

92/100

16cm natural cellulose pulp driver and reworked cone deliver warm, realistic vocal timbre with low coloration; reviewers consistently cite clear, natural midrange and strong vocal presence.

Treble

90/100

25 mm silk-dome tweeter with EFS waveguide yields precise, even high-frequency dispersion and a refined, non-harsh top end; comments note slightly softer treble but very controlled and detailed.

Soundstage Imaging

87/100

Waveguided tweeter reduces directivity and gives stable imaging, but the front port and cabinet tuning trade some depth for bass control; reviewers recommend toe-in experimentation to optimize depth/coherency.

Dynamics

89/100

Good sensitivity (90 dB) and power handling with cooling and motor design lead to strong micro/macro dynamics for the form factor; listeners report no shortage of headroom in typical rooms.

Build Quality

90/100

Solid engineering: DVAS driver integration, reworked cone profile and dual-function rubber pads reduce parasitic vibration and resonances; finish and construction repeatedly described as excellent.

Features Connectivity

82/100

Passive two-way with double binding posts supporting bi-wire/bi-amp (+2). Front port and binding-post design improve placement flexibility. (Passive baseline applied.)

Value for Money

88/100

Multiple reviewers call it affordable and a strong performer for the price (reports of €549–$599–$649 listings). Given performance vs peers in the sub-$700 bracket, it represents very good value.
