This is the simplest Subwoofer Low Pass filter Circuit using uA741 single op amp ic. The
circuit is very low cost with respect to their work. The cut off frequency of this circuit is 25Hz to 80Hz maximum. Using this circuit , you can easily design a 2.1 Sub-woofer Speaker System at your own Home. The circuit contains very few components.The cost of this circuit with PCB is Rs:45 The same circuit is working in my own hand made sub-woofer system. For power amplifier you can using this OCL subwoofer using 2N3055,  Suboower amplifier 40W, Simple 100W subwoofer amplifier
