The Triangle Borea BRA1 are a clever solution to enhance an existing home theater setup. These effects speakers, sold in pairs, stand out for their dual function: they can serve as Dolby Atmos speakers in an upright position or as conventional surround speakers when wall-mounted. This versatility, combined with adjustable filtering and perfect integration within the Borea range, makes them a relevant choice for anyone looking to access current 3D audio formats without overhauling their system.
The trapezoidal shape of the BRA1, with its angled front baffle, serves a specific acoustic purpose. In Atmos mode, placed on top of the main speakers, they project sound toward the ceiling to create height effects via reflection. In a wall-mounted setup, this angle directs sound toward the listening area for traditional surround use.
The crossover selector at the binding post enables this dual use with two response curves: linear for direct emission, and treble-compensated for ceiling reflection. This technical detail, often overlooked elsewhere, reflects a thoughtful approach to the challenge of reflection speakers.
Triangle uses the proven transducers from the Borea line. The 25 mm EFS fabric-dome tweeter features the distinctive dual-finned diffuser, improving dispersion. The 16 cm mid-bass driver in cellulose pulp—a generous diameter for this category—extends down to 90 Hz.
The compact cabinet (206 x 180 x 300 mm) maintains Borea’s construction standards with four available finishes. Removable magnetic grilles protect the drivers while preserving aesthetics.
The BRA1 can be placed directly on the BR03, BR07, BR08, BR09 and BR10 models, with carefully designed stability. Possible configurations range from 3.1.2 to 9.2.4, allowing for progressive system upgrades.
Tonal coherence with other Boreas ensures pleasing uniformity as effects move through space, avoiding the sonic discontinuities that betray composite systems.
Founded in 1980 by Renaud de Vergnette in Soissons, Triangle has been developing its own drivers since 1985. This comprehensive command of design enables innovations such as the patented SPEC system.
After a period of partial offshoring, Triangle brought assembly of its mid- and high-end ranges back to Soissons. Launched in 2019 and awarded the 2020–2021 EISA prize, the Borea range successfully democratizes proven technologies.
Technically, the BRA1 can be used with any speakers that have a sufficiently flat surface on top (for Atmos mode) or mounted on a wall independently. However, aesthetic harmony and, above all, tonal coherence will be optimal with other Borea models that share the same transducers.
Use “reflection” mode when the BRA1 are oriented toward the ceiling (Atmos configuration on top of main speakers). “Direct” mode is suitable for wall-mounted surround installation. The selector automatically compensates for the acoustic characteristics of each configuration. An incorrect setting results in either an overly dull sound (direct mode in an Atmos setup) or an overly bright sound (reflection mode when wall-mounted).
Although equipped with an uncommon 16 cm woofer for their category, the BRA1 are still designed for effects reproduction. Their low-frequency bandwidth is limited to 90 Hz and their power handling of 80 watts makes them best suited as complementary speakers. For primary stereo use, even in a small space, the BR02 or BR03 from the same range are more appropriate choices.
