Project of bringing back the old Soviet-era S-30 "Raditechnika" speakers 1983. It is a classic, one of the best in the USSR and the most widespread speaker systems, which is known by all.
Our team decided to make the desktop system "all together" with an amplifier and a power supply, plus a bluetooth. Also added battery inside.
Additionally, filters with the same components have been completely redesigned. The speakers were restored because they were in a terrible state.
As a result, we got a nice speaker system for home use.
