subwoofer filter circuit
Hi,
I have a subwoofer enclosure and I need to add some sort of filter for not to let pass audio signals from 25hz to 0hz since from 25hz to below the subwoofer exceeds the xmas.
Can you give me some suggestions like variable sybsonic filter circuits or excursion...
Can you help me step by step for this problem please ?
A filament lamp rated at 300W, at 100V is to be connected in series with a capacitor across a 230V, 50 Hz supply. Calculate the value of the capacitance, the current taken by the circuit and the phase angle.
thanks
