EFS tweeter :
The tweeter equipped in the speakers of the Borea range benefits from a new generation system called EFS (Efficient Flow System). This system is based on the combination of a 25mm silk dome known for its neutrality, and a phasing piece, specifically developed to homogenize the diffusion of high frequencies. This system drastically reduces the directivity factor, regardless of where you are listening in the room. The driver's diaphragm is placed inside a horn cone, limiting edge effects for a clear high-frequency sound reproduction. This transducer is powered by a neodymium magnet motor, capable of generating a large magnetic power for a small footprint. It is associated with a heat sink to guarantee a better power handling.

Natural cellulose mid range driver :
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.

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 a perfect contact between the driver and the bracing, thus reducing the vibrations generated by the driver and transferring only 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 BR02s 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.
