This competition forces each company to produce not just good speaker systems, but also to pay attention to design. If you are indistinctive on the market, you simply wont be noticed.It is hard not to notice the products of Mordaunt-Short. Moreover, it is harder to confuse them with any other. Here are, for example, the monitor speakers MS912, which refers to Classic series. Well, how can it be the classic? It is a solid hi-tech if compare with others.An old-fashioned filter of the second order is used for the separation of bands and the frequency is chosen too low. A long-stroke 165mm driver with a spherical concave diffuser, made of aluminum with CPC cover, plays the middle and bass. High input power is worth mentioning among other its features. The tweeter is also with metallic dome.Rounded and quite well damped sidewalls of MS912 have wood grain vinyl finish. The front wall looks futuristic - the entire area is closed by the plate, stamped of aluminum. Only dustproof cover with a powerful frame of MDF on the face looks as classic design decision - like in expensive systems. On the back panel we see the bass-reflex port and jack block with two pairs of terminals.This system is able to destroy all the stereotypes. The most of music lovers thinks that in audio system compact monitors can provide bass, acceptable only by quality but not by quantity. Well, MS912 give basses of such depth and pressure, which the owners of floor acoustics cant dream of.However, everything is not very smooth with quality. In lower range MS912 has boomy side-tones. They appear not always but only on some instruments or frets of bass-guitar. The bass reflex also slightly whistles sometimes, but as it is put back, only whose owners of this acoustic should worry, who is going to place the speaker systems very close to the wall (it will act the role of a reflector and will make the whistle more noticeable).The dynamic possibilities of this pair earn a separate topic. The reproduced material is given expressively, in a big way, without any stiffness. This is a very good quality, which is important for music of any genre. But at the same time a retard is felt in each dynamic contrast and in each blow. The drive is turned out to be soft; the rhythmic structure loses its rigidity and is if macerates. Old, good rock-n-roll sounds not so crazy on MS9112 as desired. But modern at the dance-floor house bursts and sweeps over the room like a hurricane.Clearly localized scene, quite linear middle and the detailed top very attract at the playing of classic or acoustic genres. These speaker systems manage to play brass and strings and any vocal very truly (just perfect for its price) - from baritone to falsetto. So there are no serious limits, but the lovers of hard-rock or modern thrash-metal or any other adrenaline music may find this acoustics too intelligent
