Hello friends. For a long time already, about 5 years I had unfinished acoustic systems, but recently I decided to finish them all the same. The speakers consist of a bass segment, which in turn is built of a double membrane stack, each with 4 stators and 3 membranes, a total of 6 membranes and 8 stators composed by isobaric. As well as a high-frequency emitter. Everything that I do I will gradually spread here.
