TRIANGLE Solstice 3 Hi-Fi Bookshelf Speaker

Product Description

The TRIANGLE Solstice 3 is a premium hi-fi bookshelf speaker designed to deliver spacious, expressive sound from a compact cabinet. As the successor to TRIANGLE’s iconic Comète bookshelf speaker, the Solstice 3 brings a refined 2-way acoustic design, an advanced 25mm magnesium alloy barrel-type horn tweeter, and a 16cm natural cellulose pulp midwoofer together for a balanced, detailed, and highly musical listening experience.

Built for rooms from 10 to 35 m², the Solstice 3 is equally impressive in a compact stereo system, desktop hi-fi setup, or immersive home theater configuration. Its open soundstage, realistic vocal reproduction, controlled low frequencies, and lively dynamics make it a versatile choice for music lovers and cinema enthusiasts alike. With SOLSTICE technologies such as the TZ2540MG horn tweeter, DVAS internal reinforcement, a hidden laminar bass-reflex port, and a 2° tilted vibration-damping base, the Solstice 3 pushes the performance expectations of a bookshelf speaker while maintaining elegant TRIANGLE design.
