ELAC BS123/ ELAC sub 111.2

Here one additional representative of German acoustic school, moreover recently appeared in sale. The novelty ELAC BS123 entirely does not approach under the determination of miniature - nevertheless the width of front panel in monitors 175 mm. then the form in it the most serious. Facade is painted silvery “metalized”, the long-stroke 140- millimeter midbass is remarkable by concave aluminum diffuser and by very powerful magnetic system. The tweeter has a metallic 25- millimeter cupola, but it appears uncommonly - its large part is covered by flange and aperture body, and entire driver is additionally protected by fine wire mesh. Phase inverter is located from behind, but in the complete set are applied the porolon tubular silencers, which make it possible to more accurately dispose basin it cannot be also not noted irreproachable manufacturing quality BS123 and excellent terminals for the two-wire connection. Columns are characterized by the average sensitivity (87 dB) and 4- ohm impedance.

The subwoofer with the 20- centimeter head, which by the construction is identical to [midbasam] (concave aluminum diffuser, powerful magnetic system), has the narrowed form. The large rounded off phase inverter is brought out to the frontal panel. The frequency of filtration can be changed from 40 to 180 Hz. low-level entrance is made monophonic, then high-level are by three entrances and three outputs - besides traditional L and R added also entrance for the signal from the central channel. Original and, perhaps, reasonable solution.

Sounding the second German complete set was pleased by the cleanliness and the coordination. A good agreement between subwoofer and monitors can be attain both with the low frequency of tuning and with that increased to 120 - 140 Hz. the sonic scene in execution OF BS123 is scale, with a little amalgamated sources. At the height and the detail of reproduction - the acoustics issues the mass of musical information in entire range. Dynamics seemed a little compressed, and tone balance - slightly inclined downward toward the high frequencies, why sound is comfortable, even affectionate. Then there is no hint for the painting. If measurements show AChKh without sharp local failures and takeoffs, I not a bit will not astonish. This is firm handwriting ELAC.

Dependence of the module of impedance on the frequency ELAC BS123 Very competent construction - nominal resistance 4 Ohm, but after 2 kHz it does not fall below 8 Ohm. This means that in the most complex, the Hf- range from the amplifier the increased current will not be required. Port is disposed on 60 Hz, filters - on 2600 Hz. in them, apparently, are located the phase correction chains, since the peak of impedance near the division is low. Accordingly, and the reactive component of load is minimum.
Total AChKh of the satellites ELAC BS123 and of sub 111.2. Satellites gears have unusually the flat characteristic over a wide range of frequencies with a good approach into the Lf- region. The decrease in the sound pressure on -3 dB in them is observed at the frequency of 50 Hz, almost as in floorstand speakers. Sensitivity average, on the order of 88 [dB]/2,83 [v], so that to the selection of amplifier one should relate [povnimatelnee]. Dispersion is splendid: the curves, taken with the deviations from axis 30 and 50 deg., completely repeat each other. There are the foundations for hope for the stable scene and the clear localization of sources. [Sabvufer] successfully supplements satellites gears, for the flat jointing to it is sufficient half of service band. Entirely accurately it is possible to be built by level regulator.
