The sotabeams filters are exceedingly good technically. It’s the flexibility and user interface that’s stinks. And, of course, it can’t be modified, even though the processor has plenty of resource for additional computational things like a nice display to graphically show you the filter contour.

The sofa beams Audio DPS boards...there are several models...are stand alone boards, no coach needed. Simply insert in your audio chain and add power. It works great. Far better than I had hoped. They are worth the investment.

That looks like a cool implementation. Is your audio bandpass filter stand alone or is it an add-on to the Sotabeams filter board?
