[QUOTE="Ivan Beaver, post: 39992, member: 30"] Re: Here's the picture you ALL have been waiting for LEts say you want to use a 30hz highpass. so you are wanting to say cut 20Hz. Look at the attached graphs. At 20Hz, with a 24dB filter, it is much lower in level than with the 12dB slope. I agree-a 24dB Butterworth is my highpass (for subs) of choice. Other bands depends on what I am trying to do with the adjacent band. But the bottom end of subs have no adjacent band-so kill as much as you can. BUT using higer order filters will result in additional problems-so 24 dB is the max I usually use. [/QUOTE]
