The Triangle Borea BRS1 is a dedicated effects speaker designed to enhance your Home Theater setup. Featuring switchable bipolar/dipolar technology, it delivers 360° sound diffusion that immerses you in the heart of the action. With its dual 25 mm fabric dome tweeters and 16 cm midrange/woofer made of natural cellulose pulp, the BRS1 faithfully reproduces the sound effects and atmospheres of your favorite movies and series. Its simplified wall-mounting system and slim profile allow for discreet integration into your home, while its damping system decouples the speaker from the wall for optimal acoustics.
The BOREA BRS1 follows in the footsteps of TRIANGLE speakers, renowned for their exceptional sound quality. Its two-way design incorporates a 16 cm midrange/woofer with a natural cellulose pulp membrane, a material favored by TRIANGLE for its ability to reproduce voices with great fidelity. This membrane also provides wide sound coverage, essential for an effects speaker.
The 25 mm fabric dome dual tweeter EFS (Efficient Flow System) is the acoustic signature of this speaker. Unlike traditional speakers equipped with a single tweeter, this dual setup enables 360° sound diffusion throughout the room. This configuration ensures precise high-frequency reproduction while maintaining the characteristic warmth of TRIANGLE sound, creating an enveloping soundscape that transports you into the action.
The 91 dB/W/m sensitivity highlights the efficiency of these speakers, requiring relatively little power to deliver high sound levels. This feature makes them compatible with a wide range of amplifiers, even those with modest power output.
One of the key strengths of the BRS1 lies in its versatility. Thanks to the selector located on the back of each speaker, you can choose between two operating modes depending on your Home Theater configuration:
The bipolar mode ensures uniform sound diffusion, ideal for classic 5.1 setups. In this configuration, both tweeters emit in phase, creating a homogeneous sound environment that envelops the listener.
The dipolar mode, on the other hand, optimizes spatialization in more advanced configurations (7.1, 9.2, etc.). The tweeters operate in opposite phase, creating a diffuse sound field that enhances the perception of surround effects and reinforces the sense of space.
This flexibility allows the BRS1 to adapt to different room sizes and installation setups, always ensuring optimal sound reproduction. Whether you have a compact living room or a large dedicated Home Theater space, the BRS1 adjusts to your environment.
The BRS1 inherits the technologies developed for the entire BOREA range, ensuring perfect sound consistency when paired with other speakers from the same family. This homogeneity is crucial in a Home Theater system, where the transition of sound between different speakers must be smooth and natural.
The BOREA range has received numerous awards, including the prestigious EISA 2020-2021 “Best Value Home Theater Speaker” award. The BR03 bookshelf speakers earned 5 stars from What Hi-Fi magazine, while the BR08 floor-standing speakers won a Diapason d’Or. These accolades attest to the acoustic excellence of the range from which the BRS1 originates.
To create a complete Home Theater system, the BRS1 can be paired with BOREA floor-standing speakers (BR07, BR08, BR09, or BR10), bookshelf speakers (BR02 or BR03), and the BRC1 center channel. This modularity allows for configurations ranging from 2.0 to 9.2.4, suitable for all room sizes and budgets.
Despite their compact size, the BRS1 delivers impressive acoustic performance. Its frequency range of 55 Hz to 22 kHz (±3 dB) covers the majority of the audible spectrum, ensuring faithful reproduction of sound effects, atmospheres, and film music.
The 90-watt RMS power handling allows the BRS1 to reproduce the most dynamic scenes without distortion, even at high volumes. This power reserve is particularly appreciated during intense action scenes, where surround effects play a crucial role in the cinematic experience.
The variable impedance (4.6 to 8 ohms) facilitates pairing with most Home Theater amplifiers on the market. This technical feature, often overlooked, is essential for ensuring optimal compatibility between the speakers and the electronics driving them.
In bipolar mode, both tweeters emit in phase, creating uniform sound diffusion ideal for 5.1 configurations. Dipolar mode makes the tweeters operate in opposite phase, generating a more diffuse sound field that enhances spatialization in advanced configurations (7.1 and above). The choice of mode depends on your setup and room acoustics.
The BRS1 is specifically designed as an effects speaker for a Home Theater system. For stereo listening, it is better to opt for the BR02 or BR03 bookshelf speakers, or the floor-standing speakers from the BOREA range, which offer a more balanced soundstage and better bass extension.
The BRA1 are Atmos effects speakers designed to be placed on top of floor-standing speakers, projecting sound towards the ceiling to create a vertical dimension. The BRS1 are traditional surround speakers meant to be wall-mounted for lateral and rear effects. These two models complement each other in a complete Dolby Atmos setup.

Amazing surround speakers used with a Marantz 40 and only for home theater. With this amp, they reproduce all the surround effects perfectly, just like at the cinema.
Perfect for their size.

Works properly, but not easy to install because the template doesn't match the exact size of the speakers!
