EFS Tweeter

Diffusion in the space

The tweeter of the Borea series is equipped with a next-generation system called EFS (Efficient Flow System). It is based on the combination of a 25mm silk dome, known for its neutrality, with a phase plug specifically developed to homogenize the high-frequency diffusion. This system significantly reduces directivity regardless of the listening position in the room.

Midrange in Natural Cellulose

Unique tonality

The Borea series, inheriting the technological innovations of Esprit Ez, also incorporates a midrange driver with a membrane made from 100% natural cellulose paper, without any surface treatment. This paper membrane, unique to TRIANGLE, avoids any coloration of the intermediate frequencies.

Powerful, Capable, and Accurate Low Frequencies

The mission of TRIANGLE's engineers is to deliver a rich and dynamic sound in the low frequencies, emphasizing rhythm without distorting the music. The DVAS (Driver Vibration Absorption System) reduces internal vibrations in the cabinet.

• The internal panels are braced with MDF & EVA foam to enhance the combined structure.
• Significant research has been conducted to reduce internal vibrations.
• Each speaker in the Borea series features its own decoupling system.
• All speakers come with a magnetic protective grille, without visible inserts or screws.
