380-2000 EXC LC FIELD-COIL Low frequency driver / 8 Ohms
380-2000 EXC LC FIELD-COIL Low frequency driver / 8 Ohms
EXC series
The goal of the EXC series, maintaining the philosophy of SUPRAVOX, high-efficiency full-range loudspeakers. With the EXC (Field-coil Loudspeaker) series, from 165 to 380 mm in diameter, the audiophile can satisfy his passion. The Supravox team, always looking to improve their products, offers four evolutions of these classic references equipped with a powerful electromagnet.
The moving parts benefits from our new exponential cone which, by the formulation of its paper, offers better damping, a guarantee of clarity and definition, while ensuring, by its profile, greater rigidity offering reduced distortion in the low register.
This brand new loudspeaker is a reference in high fidelity: bandwidth, linearity of response, clarity of sound, dynamic range, thermal and mechanical resistance, very low distortion.
This driver requires an external power supply from 6 to 12v at 5A max.
