Hi all,
What would be the best op-amps, single and double, for use in bass filter, up to 150Hz ? I already have a low-pass filter with 24dB slope. As I only need 12dB slope, can I remove the resistors and caps in the second part of the filter, incert new values, and in this way make a hi-pass section for EQ-ing in the low bass(30Hz).
