Medium in natural cellulose:

The Borea range uses a midrange driver with a 100% natural cellulose pulp membrane that does not undergo any surface treatment. This avoids any coloring of the intermediate frequencies in order to reproduce voices with realism, while offering a characteristic grain of the most beautiful effect. The profile of the membrane has been reworked to increase the rigidity of the speaker and improve its frequency response.

Percussive bass:

Triangle focuses on fast and accurate bass drivers, using a large motorization and placed in a specially optimized cabinet. The result is a punchy and immediate bass that promotes a controlled rhythmic reproduction. The bass transducers integrated here use a glass fiber membrane. This material ensures a high impact force, without impinging on the vocal register and the overall coherence.

DVAS system:

Following extensive research to reduce internal vibrations related to the cabinet, the Borea range of loudspeakers incorporates openwork internal panels made of MDF and EVA foam to stiffen the transducer and cabinet assembly. This process reduces structural vibration while absorbing low frequency vibrations.

This proprietary system, developed by Triangle and named DVAS (Driver Vibration Absorption System), uses a high-density EVA foam gasket at the end of each internal bracing, ensuring perfect contact between the driver and the bracing, thus greatly attenuating the vibrations generated by the driver, which only transfers a small amount of vibration to the cabinet. This DVAS system ensures a high degree of neutrality and clarity, without sound coloration.

Decoupling :

Each speaker of the Borea range has its own decoupling system. The BR03s are delivered with rubber pads, protecting the underside of your speakers, but also limiting the transmission of vibrations.

Magnetic cover :

All Borea loudspeakers have a magnetic protective cover, leaving no screws or inserts visible.
