Our SONIC signature
The TRIANGLE sound can be described as extremely dynamic, balanced and focusing on that bandwidth where the music really happens. With TRIANGLE speakers, you don’t listen to a concert, you feel it.
The woofers have a glass fiber membrane, with an inverted half-roll suspension, to assure the driver stops quickly and precisely. This technology prevents any unwanted resonance and produces top quality sound.
