Since 1950, the DGS-0.25 subscriber loudspeaker has been producing the Oktava Tula Plant. "DGS-0.25" stands for Dynamic Network Loudspeaker, with a power consumption of 0.25 watts. Subscriber loudspeakers were produced in various designs and from the factory were designed for a 30 volt radio broadcast network. If necessary, and using the taps at the transitional transformer, the loudspeaker could be switched to a voltage of 15 or 60 volts, and some instances to 120 volts.
