RUBBERFILTER is a stereo filter which also allows you to process each channel seperately. A magnitude display bar at the bottom provides a preview of what is filtered out.
The plugin offers filters of up to 384dB/Oct and you can change the steepness in 6dB steps starting from 6dB/Oct. Here's a plot of 4 different filter orders (2nd, 4th, 8th and 64th order = 384dB/Oct):
