Hydra SP 7.1 horn-loaded subwoofer with a circular cross section horn, is characterized by extreme sensitivity, dynamics and emission power, made with an incredibly rigid and light structure in durable composite materials.

Unlike all other alternatives currently available, this low frequency loudspeaker has been realized without technical and dimensional compromises, being fully developed both in terms of length and radiating surface. This it achieves maximum acoustic performance combined with an elegant design and personality, always keeping dynamics and control front and center.

Nearly scratch proof surfaces and resistance to atmospheric agents combined with extremely high efficiency and world class sensitivity allow the Hydra to perform favorably compared with any product from the main competing brands.
