Speaker pair ADAM S3A

ADAM German company specializes in professional studio monitors. But as an AC line and "Home". The model under consideration is the active monitor S3A medium action. Design patterns characteristic of many speakers ADAM: beveled corners of the front panel and metal protective grille characteristic square tweeter. The tweeter uses a technology all models ART, based on the use of the bellows as sound-emitting element. AC has two 186- mm speaker with HexaCone- diffuser (diffuser cell Kevlar). One of them acts as a mid / bass driver, while the latter is limited to low-pass filter at 150 Hz and is used to "seal" the bass part.

ADAM model gives a comprehensive view of what a high-end studio monitor. There is every reason to call sound systems sverhanalitichnym. Sure, it's a high-precision, sensitive, precision tools for professional work with phonograms. If we imagine the musical material in the form of a set of precisely calibrated scales, this active speaker provides guaranteed ear perfectly balanced, authentic way through instrumental exact values for each of them. Several in the background is the spatial aspect of the image. Of particular note is the perfect tonal neutrality, the highest timbre and a wide dynamic range. In detailing no deliberateness, exaggeration. Speakers fairly clean reproduce much of the lower case (upper and mid-bass). ADAM some sound may seem a little distant, dry or rational - probably the reverse side analytism.

Ribbon tweeter, made by technology ART, closed special protective grille. The power button is on the front panel.

Most active speakers fitted to our test only professional connector XLR. Only this connection method is, for example, ADAM S3A.

Fig. 1. Frequency Response.

Fig. 2. Nonlinear distortion factor.

Frequency response of German speakers is nearly linear, especially noticeable at the range from 400 Hz to 2 kHz, the curve graph almost turns into a straight line. At low frequencies seen a slight rise in the vicinity of 100 Hz, which is a bit "heavier" bass. Light from the low-frequency fluctuations, "hillock", and to the straight section as described above has a small amplitude and a noticeable effect on the sound does not have. After 2 kHz response tends to decline by approximately 5 dB to the border at 7 kHz. In the high frequencies from 10 kHz to 20 and you can see a small dip, too, by 5 dB. Despite all the fluctuations (I must admit that very slight), AC display very good unevenness. The maximum value reached in the main band from 1300 Hz to 20 kHz is 1.47 dB. The minimum value of our measurements - 0.77 dB in the range of 160 Hz - 1.3 kHz. Speakers start to play from 37 Hz, which is one of the best results on the test measurement. AFC shot from angles other than the axis listening suffer from severe failure (more than 10 dB) in the region of 1 to 2 kHz. Also suffer and treble. SOI column data is minimal when the average signal level in the frequency range, and generally is 0.29 %. With increasing levels of up to 94 dB distortion increase, but not much - to 0.41 %. In the low-frequency range speakers sound best when strong signals (THD is 2.16 %).
