Try this link i hope you find the answer it is for subwoofer. Take note you have a Power amplifier to run a subwoofer speaker, this cicuit is driver only.

That Greek sub-woofer filter circuit is a nightmare. It is a project at Electronics-lab.
Its schematic does not agree with its parts list which does not agree with its parts layout because some capacitors are actually two capacitors in parallel.

The translation from Greek to English is a joke.

anyone please help me! i need an schematic diagram for an improvised microphone using a speaker..

 

[audioguru]

A speaker makes a poor microphone because it has a low frequency resonance that makes it sound "boomy".
An electret microphone has excellent sound and is inexpensive and small.

tl072 OP-AMP IC based low pass filters are common nowadays

You've hijacked someone else's thread. Poor netiquette.
Re the mic, have a look at this other thread :-
