I'd appreciate some feedback from you folks who've done this before. I feel a bit uncertain setting the bandwidth parameter. I find the peak of the freq. (dB), then see how wide the peak is (Hz), then convert from Hz to fractional octaves for the width. For instance: a peak at 46 hz with the valley to the left bottoming at 40 Hz.. I figure +/- 6 Hz... or 8/60ths octave. ((8/60)*46). Is this the way you guys figure the bandwidth? Anyway, using the right front corner since it gave the flattest response, I set up 3 filters and fumbled my way to this: If the graph doesn't come up, try this link. At this point, understanding that I'm expecting an improved sound, I am pleased with my first efforts. I was hoping to get less of a sawtooth effect, and probably can once I get comfy with adjusting the parameters of the BFD. Next up: eq for the LF corner.. and then decide which corner sounds best. Edit: corrected the corner placement to the RIGHT (not left) front corner. sheesh.
