Architettura Sonora

Spherina Air

Spherina goes back to the Architettura Sonora's roots, Sphere, an iconic image of High-End speakers, reworking and redisigning the shape into a new context, using new materials and refined details.
Characterized by a dual concentric 6" transducer, with coaxial mid-woofer and tweeter to create a virtual point source, linear and time coherent, providing a uniform omnidirectional coverage over the vertical axis
