The Mission 731i is two-way speaker system of bass reflex type with dimensions 175x315x200 mm. Plasticized paper cone of low-frequency speaker has a diameter of 130 mm, composite dome high-frequency head - 28 mm. Respect deserves a responsible approach of developers to acoustic clearance of speakers. Emitters are fixed in such a way that the low-frequency one is connected mechanically with the rear speaker and the tweeter - with faceplate. This solution is very useful for correct interaction of sub-bands. The reflex port, located on the front panel, is divided into two channels. Speakers Mission 731i looks very attractive and will look good on a shelf, and on the special firm stand, and on the wall. Recommended power range amplifier is 35-75 watts. Frequency response, of course, belongs to system of the high class. Very tight are look undersides, it is much of the credit bass reflex. The average frequencies are ironed in the best traditions of hi-fi, a conjunction of sub-bands is close to ideal. The uneven characteristics in the region from 1 to 4 kHz are bit more than +/- 1 dB. The high-frequency speaker organizes its sub range quite rationally - there is nothing superfluous, and at the same time has everything you need: high uniformity is necessary in the area of maximum sensitivity of the ear, there is easy lifting of characteristics from 7 to 16 kHz, and there is no wasteful desire to get into the ultrasonic region. The sensitivity of the system in accordance with the technical description is 89 dB at 2.83 V at one meter. Our measurements yielded a value of 3 dB less. The positive point is low directivity of speakers Mission 731i that provides wide area of robust stereo. At the time of placement, there is no need to strive to ensure that the acoustic axis of the emitters strictly crossed in the head of the listener. The system sounds full when listening to the whole genre diversity of musical works. Judging by the description module of input impedance, the frequency of the inverter is 50 to 60 Hz; nominal impedance, in accordance with technical description, - 8 Om.
