Now the translation of the article promised by me from magazine on English language. At once I ask to excuse for some possible errors of transfer
Everything has begun, really, with «a new radio tape recorder» if it is fair in relation to multimedia 2-din JVC with a multichannel sound. Time so - means, already both front, and back, and, if on that has gone, it is necessary to do the centre seriously. The subwoofer is is not discussed at all. The novel, the author and the main conductor of the project, told, that many ideas of installation came as though from air, on road to studio. For example, unusual dual acoustics of front. Here two complete sets componental Hertz HSK 165 are established, but... The different. One complete set - standard, there in a role of an acoustic column reproducing a range of an average bass - head HV 165 with the switching centre from synthetic polymer, and in the second a similar column have replaced on HV165 L is a version for three-lane systems, with "reaped" cellulose диффузором and the parametres optimised for area of the bottom frequencies.
Both mid-frequency columns work on the general for them door volume, a door for a compartment big, suffices both. Certainly, the door has been essentially finished: all available surfaces, and there where they lacked - in technological windows of the internal panel are strengthened, have been put new, from several layers of a rigid noise isolation. The unprofitable podiums supporting natural contours of upholsteries of doors, the Novel does not recognise, therefore upholsteries have been altered so that mid-frequency columns in them have sunk. Heads thus lean against the dual prorate from several layers MDF, and after assemblage a door upholstery, a flange dynamics, a plastic basic ring, the prorate and the door panel are pulled together in an indestructible sandwich. Logos on the lattices, not quite corresponding to mark of columns, have appeared during selection of the details optimum entered in a design. Basic rings too not "native", they - from acoustics Helix, it is simple on them it is not written. And where it has been written - have left in a gratitude sign to mark-donor.
High-frequency - too doubled, but identical. Them have established in the nonconventional image, having united in one system two classical variants of an arrangement of Vch-radiators. One steam of high-frequency columns - on the racks, the second - in corners of mirrors. It was (and is, it is not finished) experiment, by means of such configuration the Novel and Oleg wished to test possibility of adjustment of system by capacity redistribution between these acoustic elements, and without strengthening for each channel, one passive filters and devices lowering loudness of a sound. Both mid-frequency and high-frequency elements of acoustics of the car are included through regular crossovers and connected in a parallel on inputs of filters, forming loading in two ohms for each of two channels four-channel Helix Dark Blue. Pair which has remained with it of channels works on back (read - surround, on exhaust JVC - a high-grade multichannel sound). The back is made curiously. Four included parno-in parallel 13-centimetric coaxials Hertz HCX 130 are established in the such arch stretched between boards of the car. This arch - not simply support for acoustics of the car, but also an element of acoustic registration, from below to a relief composit surface volumes for mid-frequency back are attached. «The closed volumes», - other reader-pedant will correct us and will be not right. Half-opened. The novel already has for a long time estimated advantages seldom whom of applied similar loading, here it and is used: one of walls of acoustic boxing on each board is made punched and sewn up by several layers of a synthetic winterizer (the number of layers stole up by practical consideration).
Registration of acoustics of the central channel is similarly arranged also. Chronologically the centre even has acted as the first in application of the given loading if in back there were variants, here they were not. In the first version, still approximate, a 4-inch coaxial of the centre have put free air, it worked on all space of the instrument panel of the car. Also it has appeared, that it does not approach. At the levels of a signal proportional to return of front on especially intense places of a soundtrack, for example, when in «Pearl Harbor» the Japanese airplane flies by over a head, the central element of acoustics choked, as if being indignant with impudence of the Japanese soldiery. Have tried a classical way, but had not time to finish plainly at all test as it was found out, that the place in the instrument panel did not suffice under a little decent volume, and to fence the Egyptian pyramid - against principles of the designer of system and tastes of its customer. Has gained a known way: Central acoustics "breathes" under the instrument panel through the acoustic brake similar applied (then) in rear link.
Luggage carrier... It is separate history, probably, see. The novel and Oleg, to this phase of work on system - already a command of adherents, moved components this way and that while the idea has come to a head (they now cannot recollect at all to whose) to collect from audiosystem components as though the second motor. And too V6, certainly.
«The block of cylinders» if it is possible so to be expressed, is formed by the subwoofer case. It (the closed box in volume of 60 l on both heads) consists of two parts which are based on «the central frame» - a plate from MDF, leaning against a trunk floor. From it downwards goes powerful, with thickness of walls about 20 mm, a cover from fiber glass, it occupies all niche for a spare wheel (it have refused). At cover manufacturing in "Tuning fork" use firm reception, when at a finished article an external layer - not a rigid material from fiber glass, and extinguishing any parasitic additional sounds from contact to a body a layer vibration-isolation. Above there is a superstructure of oval section (flat surfaces - MDF, curvilinear - fibreglass) at which top there are two "tens« MTX of pathos "eight-thousand" series. On each side turned out «the air filter» - heads of cylinders of "the second motor», four-channel Helix Dark Blue. We have already attached one of them, the second same works on subwoofers, they are connected everyone to the pair channels by the bridge. As a result all eight channels work or on 2 Ohm, or the bridge on 4, what too as though on 2, feel unity of the concept? In total on two, even the Ohm in loading...
Eight... Wait a moment, and the centre? For it have put the separate amplifier - compact two-channel Thunder 202. It has hidden in the bottom part of the block of cylinders and works on acoustics only as one channel. How so? Concept infringement? However, apparently, the only thing: on the other hand the unit two buffer condensers restoring dual harmony are established.
Separate aspect of tuning of the car - light engineering. Regular optics, on Novel expression, «executed the first», headlights have collected from modules Hella, back - light-emitting diode rings, forward - manual work of a ruler from the brightest 4-crystal light-emitting diodes what can be found. The owner of the car guarantees it: searched on all city now does not remember how many, whether week, whether two. Probably, two - such concept...
If, suddenly, to you places the translation into English is not clear, quote me and I will try to explain differently...
