All electrolytic capacitors must be rated 100v. Subwoofer amplifier circuit design. Here we designed a sallen key low pass filter using opamp lm7332.
This is circuit of active subwoofer circuit by using x4 ic tl082 or you can using equivalent ic 4558 jrc4558d jrc4558 tl072.
Select your woofer quantity and woofer impedance to see available wiring configurations. Here we designed a sallen key low pass filter using opamp lm7332. In stereo mode each half of the tl072 operates as a non inverting input amplifier with a gain of about 2 8 times as determined by feedback resistors r5 and r6. Use a 100w 12 inch sub woofer at the output.
