Help Creating Bass boost filter.

[PaulHilgeman]

I have measured my room, and I have a horrid dip in bass from 35 Hz to 55 Hz. This is really affecting my bass response since I have now moved to an integraded amp with no bass adjustment. Could someone help me to build an active circuit that would boost bass in these frequencies, and possibly be adjustable via a 50K potentiometer?

Or, just point me to a source. I have a bunch of opa2134 opamps to spare and lots of filtering caps and resistors.

Thanks,
Paul Hilgeman

If the dip in your bass responce is caused by room acoustics then improving room acoustics or moving your speakers to a different spot might help more than a booster.
