285-EXC mk2 Field-coil Extended bass-midrange speaker 70W 93 to 102dB 8 Ohms

EXC series The goal of the EXC series, is to maintain the philosophy of SUPRAVOX, high-efficiency full-range loudspeakers. With the EXC (Field-coil Loudspeaker) series, from 165 to 380/400 mm in diameter, the audiophile can satisfy his passion. The Supravox team,always looking for improvements, offers four evolutions of these classic references equipped with a powerful electromagnet. The 285-EXC mk2 version benefits from the new ventilated field-coil motor, whose field has been optimized under FEA software, its high manufacturing quality is ensured by a CNC automatic winder. Its magnetic field is adjustable and therefore adaptable to many speakers, it requires an external power supply (ideal from 6 to 12V for 5A). Frequency response from 200Hz to 20 kHz on axis for 9V Frequency response of 200Hz to 20kHz at 30° for 9V Frequency response of 200Hz to 20kHz at 60° for 9V Frequency response in 1/3 octave for 9V Impulse response for 9V Waterfall pour 9V Impedance for 9V TECHNICAL CHARACTERISTICS Sensitivity 1 W/ 1 m at Fs: 93 to 102dB Bandwidth : 50Hz-7KHz Impedance: 8 ohms power max.
