Outdated Product
High-quality two-way stereo speakers (2.0) with a built-in amplifier, a dense MDF cabinet, a convenient front volume control and an analog input. Positioned as a product of the middle price category of 2011. Designed for users who would like to purchase a high-quality sounding speaker system to output sound from a personal computer, monoblock, nettop or laptop. Provides a confident and loud sound, the tone of which can be further adjusted using the analog rotary controls. Microlab B-77 computer speakers are equipped with an analog input with 2xRCA connectors and are equipped with a 3-pin miniJack 3.5mm->2xRCA cable, with which you can get sound from any source equipped with an analog output, including TVs and game consoles. One of the two speakers is active and contains a power supply and...an audio frequency amplifier (based on the TDA7265 chip from ST Microelectronics). The second speaker is passive, connects to the active one and is equipped with only a speaker. 4-inch dynamic drivers with flexible polyurethane suspension and 0.75-inch tweeters provide correct reproduction of the frequency range from 55 Hz to 20,000 Hz, which is quite enough for listening to any music content (including classical and jazz), watching videos and acoustic design of computer games.

good model, I liked it
6 March 2017 
I use it for work (bioenergy sessions, chakra music, meditation), and rock during breaks. The sound - lows-middle-highs is very satisfactory (there is hearing). One speaker was quieter, and the wheezing was...through the wire, I didn’t change the wire, but I cleaned it, clamped it tighter in acidified, almost galvanized-looking clamps, and it became normal. But you need to change the wire, it would be even better, and the clamps, or solder. With the correct equalizer from the source and full bass and treble, the sound is good, at 80% volume, for this class what more could you want. Per room 16 sq.m. It’s enough if you’re not a music lover... If the source (my player) is normal, then there are no clicks, they are extinguished in mute mode, and if the player is so-so, then there are clicks.
Sound. View. Direction upward, standing on the windowsill goes exactly towards the head. No noise. They have been working every day (working days) for 8.5 years!!!!!!!!!!
He catches tips, it happens.
