Srs Tru Bass

[pra3718]

I am looking for the circuit for SRS Tru Bass circuit with op-amp. Or any similar type of circuit which can deliver good bass from small driver or low power amp.
Regards

This may be a suitable off the shelf solution:

Reckhorn B-1

Only 59 Euros...

How effective it is will depend on the power of your amp and power handling of your speakers (other factors come into it as well though).

Thank you, I wish to develop the circuit myself

Google for 'frequency multiplier' and 'mixer'. With the frequency multiplier you double the frequencies of the input signal, which gives you the second harmonic. With the mixer you add that to the original signal.
