SOUND IS ONLY A LITTLE SOFTENED, THEN IT IS CLEARLY FOCUSED AND NOT PO- BUDGETARY, IT IS INFORMATIVE AND PURE
FS 58 - top- model in the newest budgetary rule of acoustics ELAC, which left at the end 2004. German developers understood, that “[pyatidesyatki]” will fall into the segment, where the competition is most sharp, and therefore they decided to be isolated. How? They forewent the standard diagrams and the finished dynamic loudspeakers and created their, for the special requirements (in this matter in ELAC experience enormous): both midbass and midrange, and tweeter with the neodymium cooled magnet. Still they included in filters the elements of overload protection. In remaining FS 58 they are traditional: housings from MDF bear on the pair of phase inverters from behind, they are closed from face with woven anthers and stand on the platforms with the shafts.
Remembering, as in the recent test of [monitorchki] BS 53 they literally tore to pieces rivals, I something special waited also from FS 58, but… By construction sonic scene and in the transfer of upper register they are identical: sound is only a little softened, then it is clearly focused and not on- budgetary it is informative and pure. Average register is also transferred opened, in a singing voice. But the region between bass and medium frequencies is frankly elevated: acoustic tools “bulked”, impact steels of [gulkovaty], low [vokal] swam in [zhirkom]. But the again complete order is below along the spectrum: up to deepest basses is energy, and the legibility.
Closed with metallic [grilem] of [pishchalka] - very crafty solution. It made it necessary correctly to sound the woven cupola of uncommonly small curvature.
Middle and upper ranges are transferred with the model accuracy and the cleanliness, but in this case they are not deprived of nuances. Legible and fundamental lower basin.
Musical balance is disrupted by noticeable to the rumor lift in the region between the low frequencies and by middle.
These columns will extract the maximum of musicality from [audiosistemy], which with other acoustics usually issues sound dry, “degreased”, with the sandy sopranos.

One additional example of correct design and thorough production of acoustics. Nominal and minimum resistance to 3,9 and 3,8 Ohm respectively; therefore the current, returned by the final stage in entire frequency band, will be constant. Thus, with these columns will be able to work any amplifier, calculated for the 4- ohm load.
Phase inverter is disposed for 42 Hz, frequencies of the division of crossovers to determine complicatedly, since at the points of inflection there are no explicit peaks of impedance. As consequence - flat phase response, which testifies about minimum reactive component of load.

Flat curve, and if not the wide saddle in the range 1 of 10 kHz, AChKh it would be possible to consider it model. But the depth of the decrease at the quite lower point only of 3 dB; therefore the tone balance this hardly will affect. Phase inverter catches relay race on 80 Hz, where the return of [vufera] only begins to fall. With the optimum installation in the room lower register will be reproduced with the minimum nonuniformity.
In these THE speakers is one additional unquestionable merit - excellent dispersion of the tweeter. With the turning of columns on 30 deg. his return falls in all to the pair decibel; the smooth decrease begins only after 15 kHz. As consequence - correct sonic scene will be even when column cannot be placed correctly. Sensitivity corresponds to that declared, 90 dB; therefore amplifier can be not very powerful.
