![]() ![]() So far I haven't seen a textbook folter that does. One should not forget that the filter should suit the driver's requirements. He built a fine 24 dB/octave two-way using the correct values, and it includes improvements. I personally have a strong preference for more-damped-than-Butterworth filter profiles, but a lot of people don't - esp if they don't find out 'til later that that's what they're getting.Ĭheck member AndrewT's work on this. Attenuation an octave past the cutoff frequency is only around 9 dB two octaves away its only 17 - 19 dB down. A careful examination of the resulting FR shows a rounded corner, and a slope that never becomes straight. They produce a filter that is over-damped - more highly damped than even Bessel. But there is one thing I gotta point out, as this design continues to proliferate: The frequency-setting values are wrong. I like Boozhound and his philosophy, and don't want to publicly poop on his fine product. ![]() Now, I've read the manual and see that several issues are properly addressed, and won't give you trouble after all. ![]() I must have gotten my neurons crossed when I read your thread starter - somehow completely overlooking the 2nd link (with the Manual) and was imagining that you would build this up from just the schematic. ![]()
