The Borea tweeter is equipped with the EFS* (Efficient Flow System), which combines a 25mm silk dome with a specially designed waveguide for uniform high-frequency dispersion. This system significantly reduces directivity regardless of listening position.

The dome is placed within a horn-loaded part, reducing reflections and allowing clear high-frequency reproduction. The transducer is powered by a neodymium motor for high magnetic power in a compact size and features a cooling system for better power handling.

The midrange driver is made from 100% natural cellulose paper without surface treatment, avoiding any coloration of the mid frequencies. The cone profile has been redesigned to improve rigidity and provide extensive frequency response.

In three-way units, the midrange driver incorporates a small fold for motion control, ensuring natural voice reproduction.

The low frequencies are powerful and precise, aiming to deliver rich and dynamic sound without distortion. TRIANGLE engineers focus on fast and accurate drivers, housed in optimized enclosures.

TRIANGLE has used fiberglass membranes with excellent vibrational behavior to control low frequencies with a clean rhythmic result.

The DVAS (*Driver Vibration Absorption System) reduces internal vibrations using perforated internal MDF and EVA foam panels, increasing the rigidity of the combined transducer/enclosure structure.

The system isolates each speaker in the Borea series, with bookshelf and center channel models featuring suspended mounts to limit vibrations.

All speakers in the Borea series feature magnetic protective grilles without visible screws or retaining elements. It is recommended to remove the grilles during listening.
