Thanks for this discussion - it's quite helpful. Sadly, I'm ignorant of even the grosser points of FIR v IIR filters, but I especially appreciate the practical pointers.

As it turns out, I *do* work with a bit of unusual electronic music (a holdover of my youth spent collecting early Tangerine Dream, etc) but I'm just as interested in preserving the gut-feel of acoustic bass drum in jazz and rock recordings.

With a little further experimenting, I've discovered the signature rumble (approx 12Hz, -49dB) from my SOTA Vacuum Star turntable is not purely out of phase; summing this signal only provides about -5dB reduction of the signal. Perhaps if I do this as a first step then apply a 7th or 8th order butterworth filter I'll get the best results with least disruption of the signal?
