Subwoofer 150W
Subwoofer that is otherwise known as a super woofer column was made on the basis of other projects on the portal elektroda.pl. Inside there is a subwoofer Crunch USA Pro Series with a power of about 250W.
The column amplifier is based on an old plate amplifier, which has been processed. Currently, there are four power transistors KD-502 at 2 per channel, then at the end are combined in one. On the input signal is active filter musical, which initially transmits only low tones. Active power draws about 150W, which at 250W speaker, extends the life of the column.
